Detecting Stance of Authorities Towards Rumors in Arabic Tweets: A Preliminary Study Fatima Haouari, Tamer Elsayed Qatar University A myriad of studies addressed the problem of rumor verification in Twitter by either utilizing evidence from the propagation networks or external evidence from the Web. However, none of these studies exploited evidence from trusted authorities. In this paper, we define the task of detecting the stance of authorities towards rumors in tweets, i.e., whether a tweet from an authority agrees, disagrees, or is unrelated to the rumor. We believe the task is useful to augment the sources of evidence utilized by existing rumor verification systems. We construct and release the first Authority STance towards Rumors (AuSTR) dataset, where evidence is retrieved from authority timelines in Arabic Twitter. Due to the relatively limited size of our dataset, we study the usefulness of existing datasets for stance detection in our task. We show that existing datasets are somewhat useful for the task; however, they are clearly insufficient, which motivates the need to augment them with annotated data constituting stance of authorities from Twitter. 众多研究曾通过利用传播网络中的证据或来自网络的外部证据来解决推特谣言验证问题。然而,这些研究均未充分挖掘权威机构的佐证信息。本文首次定义了"权威机构对推文谣言的立场检测"任务,即判定权威账号发布的推文对特定谣言是持支持、反对还是无关立场。我们认为该任务能有效扩充现有谣言验证系统的证据来源。为此,我们构建并发布了首个阿拉伯语推特权威机构谣言立场数据集(AuSTR),其中所有证据均采集自阿拉伯语推特权威账号的时间线。鉴于数据规模相对有限,我们系统评估了现有立场检测数据集对本任务的适用性。实验表明,现有数据集虽具有一定参考价值,但明显不足以支撑任务需求,这凸显了需要补充标注来自推特权威机构立场数据的重要性。

Nevertheless, recent works have raised concerns about fairness and potential biases in the recommendation landscape since unfair recommendations may harm the interests of Consumers and Producers (CP). Acknowledging that the literature lacks a careful evaluation of graph CF on CP-aware fairness measures, we initially evaluated the effects on CP-aware fairness measures of eight state-of-the-art graph models with four pure CF recommenders. Unexpectedly, the observed trends show that graph CF solutions do not ensure a large item exposure and user fairness. To disentangle this performance puzzle, we formalize a taxonomy for graph CF based on the mathematical foundations of the different approaches. The proposed taxonomy shows differences in node representation and neighbourhood exploration as dimensions characterizing graph CF. Under this lens, the experimental outcomes become clear and open the doors to a multi-objective CP-fairness analysis (Codes are available at: https://github.com/sisinflab/ECIR2023-Graph-CF .).|迄今为止,图协同过滤(CF)方法已被证明在生成精准推荐方面优于纯CF模型。然而近期研究指出推荐系统中存在公平性隐患与潜在偏见问题,因为不公正的推荐可能损害消费者与生产者(CP)双方利益。鉴于现有文献缺乏对图协同过滤在CP感知公平性指标上的系统评估,我们首次对八种前沿图模型与四种纯CF推荐器在CP感知公平性指标上的表现进行了对比分析。出人意料的是,观测数据显示图CF方案并不能显著提升商品曝光度与用户公平性。为解析这一性能谜题,我们根据不同方法的数学基础构建了图CF分类体系。该分类法揭示出节点表征与邻域探索机制是图CF的差异化特征维度。基于这一视角,实验结果得到了合理解释,并为多目标CP公平性分析开辟了新路径(代码已开源:https://github.com/sisinflab/ECIR2023-Graph-CF)。

To alleviate this, Query Performance Prediction (QPP) models have been developed to estimate the performance of a system without the need for human-made relevance judgements. Such models, usually relying on lexical features from queries and corpora, have been applied to traditional sparse IR methods – with various degrees of success. With the advent of neural IR and large Pre-trained Language Models, the retrieval paradigm has significantly shifted towards more semantic signals. In this work, we study and analyze to what extent current QPP models can predict the performance of such systems. Our experiments consider seven traditional bag-of-words and seven BERT-based IR approaches, as well as nineteen state-of-the-art QPPs evaluated on two collections, Deep Learning ’19 and Robust ’04. Our findings show that QPPs perform statistically significantly worse on neural IR systems. In settings where semantic signals are prominent (e.g., passage retrieval), their performance on neural models drops by as much as 10% compared to bag-of-words approaches. On top of that, in lexical-oriented scenarios, QPPs fail to predict performance for neural IR systems on those queries where they differ from traditional approaches the most.|信息检索(IR)领域的评估通常依赖于事后实证流程,这些流程耗时且成本高昂。为缓解这一问题,查询性能预测(QPP)模型应运而生,其可在无需人工相关性判断的情况下预估系统性能。此类模型通常基于查询与语料库的词汇特征,已被应用于传统稀疏信息检索方法中——取得的成功程度不一。随着神经信息检索与大规模预训练语言模型的出现,检索范式已显著转向更侧重语义信号的方向。本研究旨在探讨和分析当前QPP模型对这类系统性能的预测能力。我们的实验涵盖了七种传统词袋模型和七种基于BERT的检索方法,并在Deep Learning '19与Robust '04两个标准测试集上评估了十九种前沿QPP模型。研究发现:QPP模型在神经信息检索系统上的预测性能存在统计学意义上的显著下降。在语义信号占主导的场景(如段落检索)中,相比词袋方法,QPP对神经模型的预测性能降幅高达10%。更关键的是,在词汇导向的场景中,当神经检索系统与传统方法差异最大时,QPP模型完全无法有效预测其性能表现。|code|1| |Overview of Touché 2023: Argument and Causal Retrieval - Extended Abstract|Alexander Bondarenko, Maik Fröbe, Johannes Kiesel, Ferdinand Schlatt, Valentin Barrière, Brian Ravenet, Léo Hemamou, Simon Luck, Jan Heinrich Reimer, Benno Stein, Martin Potthast, Matthias Hagen||||code|1| |Probing BERT for Ranking Abilities|Jonas Wallat, Fabian Beringer, Abhijit Anand, Avishek Anand|L3S Research Center|Contextual models like BERT are highly effective in numerous text-ranking tasks. However, it is still unclear as to whether contextual models understand well-established notions of relevance that are central to IR. In this paper, we use probing , a recent approach used to analyze language models, to investigate the ranking abilities of BERT-based rankers. Most of the probing literature has focussed on linguistic and knowledge-aware capabilities of models or axiomatic analysis of ranking models. In this paper, we fill an important gap in the information retrieval literature by conducting a layer-wise probing analysis using four probes based on lexical matching, semantic similarity as well as linguistic properties like coreference resolution and named entity recognition. Our experiments show an interesting trend that BERT-rankers better encode ranking abilities at intermediate layers. Based on our observations, we train a ranking model by augmenting the ranking data with the probe data to show initial yet consistent performance improvements (The code is available at https://github.com/yolomeus/probing-search/ ).|像BERT这样的上下文模型在众多文本排序任务中表现出色。然而,目前仍不清楚这类模型是否真正理解信息检索(IR)中那些基础且关键的相关性概念。本文采用语言模型分析领域新兴的探测(probing)方法,对基于BERT的排序模型进行能力探究。现有探测研究多集中于模型的语言理解和知识感知能力,或是对排序模型进行公理化分析。我们通过分层探测分析填补了信息检索领域的重要空白——设计了基于词汇匹配、语义相似度,以及指代消解、命名实体识别等语言特性的四类探测任务。实验结果显示了一个有趣的现象:BERT排序模型在中间网络层能更有效地编码排序能力。基于这一发现,我们通过将探测数据与排序数据相结合来训练新模型,实验表明该方法能带来初步但稳定的性能提升(代码已开源:https://github.com/yolomeus/probing-search/)。

The system, called Visconde, uses a three-step pipeline to perform the task: decompose, retrieve, and aggregate. The first step decomposes the question into simpler questions using a few-shot large language model (LLM). Then, a state-of-the-art search engine is used to retrieve candidate passages from a large collection for each decomposed question. In the final step, we use the LLM in a few-shot setting to aggregate the contents of the passages into the final answer. The system is evaluated on three datasets: IIRC, Qasper, and StrategyQA. Results suggest that current retrievers are the main bottleneck and that readers are already performing at the human level as long as relevant passages are provided. The system is also shown to be more effective when the model is induced to give explanations before answering a question.

Images are of utmost importance since they represent a visual gist of the whole news article. For example, it is essential to identify the locations of natural disasters for crisis management or to analyze political or social events across the world. In some cases, verifying the location(s) claimed in a news article might help human assessors or fact-checking efforts to detect misinformation, i.e., fake news. Existing methods for geolocation estimation typically consider only a single modality, e.g., images or text. However, news images can lack sufficient geographical cues to estimate their locations, and the text can refer to various possible locations. In this paper, we propose a novel multimodal approach to predict the geolocation of news photos. To enable this approach, we introduce a novel dataset called Multimodal Geolocation Estimation of News Photos ( MMG-NewsPhoto ). MMG-NewsPhoto is, so far, the largest dataset for the given task and contains more than half a million news texts with the corresponding image, out of which 3000 photos were manually labeled for the photo geolocation based on information from the image-text pairs. For a fair comparison, we optimize and assess state-of-the-art methods using the new benchmark dataset. Experimental results show the superiority of the multimodal models compared to the unimodal approaches.|随着多模态新闻的广泛传播,需要采用先进方法来解析不同模态的内容及其关联。图像具有至关重要的意义,因为它承载着整篇新闻文章的视觉要旨。例如,确定自然灾害发生的位置对危机管理至关重要,分析全球政治或社会事件时也同样如此。在某些情况下,核实新闻文章中声称的地点可能有助于人工评估或事实核查工作识别错误信息(即虚假新闻)。现有的地理位置估计方法通常仅考虑单一模态(如图像或文本),但新闻图像可能缺乏足够的地理线索来推断位置,而文本又可能涉及多个潜在地点。为此,本文提出了一种预测新闻照片地理位置的新型多模态方法。为支撑该方法,我们构建了名为"多模态新闻照片地理位置估计"(MMG-NewsPhoto)的全新数据集。这是目前该任务领域规模最大的数据集,包含超过50万条新闻文本及对应图像,其中3000张照片基于图文对信息进行了人工地理位置标注。为确保公平比较,我们使用该新基准数据集对现有最先进方法进行了优化与评估。实验结果表明,多模态模型相比单模态方法具有显著优势。

Jose, Jan Breitsohl|Univ Glasgow, Sch Comp Sci, Glasgow, Scotland; Univ Glasgow, Adam Smith Business Sch, Glasgow, Scotland|Social media has become an essential daily feature of people's lives. Social media platforms provide individuals wishing to cause harm with an open, anonymous, and far-reaching channel. As a result, society is experiencing a crisis concerning hate and abuse on social media. This paper aims to provide a better method of identifying these instances of hate via a custom BERT classifier which leverages readily available metadata from Twitter alongside traditional text data. With Accuracy, F1, Recall and Precision scores of 0.85, 0.75, 0.76, and 0.74, the new model presents a competitive performance compared to similar state-of-the-art models.

However, the multi-modality, complexity, and diverse nature of social media data and their platforms limit the performance of inferring such fine-grained locations and their subsequent applications. To address this issue, we present a transformer-based general framework, which builds upon pre-trained language models and considers non-textual data, for social post geolocation at the POI level. To this end, inputs are categorized to handle different social data, and an optimal combination strategy is provided for feature representations. Moreover, a uniform representation of hierarchy is proposed to learn temporal information, and a concatenated version of encodings is employed to capture feature-wise positions better. Experimental results on various social media datasets demonstrate that the three variants of our proposed framework outperform multiple state-of-art baselines by a large margin in terms of accuracy and distance error metrics.|社交帖文的POI级地理位置信息对众多基于位置的服务与应用至关重要。然而,社交媒体数据及其平台的多模态性、复杂性和多样性特征,限制了此类细粒度位置推断及其后续应用的性能表现。为解决这一问题,我们提出一个基于Transformer的通用框架,该框架以预训练语言模型为基础并融合非文本数据,专门用于POI级别的社交帖文地理定位。具体而言,我们通过输入分类机制处理多样化的社交数据,并提供最优特征表示组合策略。此外,提出层级统一表示法以学习时序信息,并采用编码串联机制以更优捕捉特征维度位置关系。在多个社交媒体数据集上的实验表明,我们提出的三种框架变体在准确率和距离误差指标上均显著优于现有多种最先进的基线模型。|code|1| |Multivariate Powered Dirichlet-Hawkes Process|Gaël PouxMédard, Julien Velcin, Sabine Loudcher|Université de Lyon, Lyon 2, ERIC UR 3083|The publication time of a document carries a relevant information about its semantic content. The Dirichlet-Hawkes process has been proposed to jointly model textual information and publication dynamics. This approach has been used with success in several recent works, and extended to tackle specific challenging problems –typically for short texts or entangled publication dynamics. However, the prior in its current form does not allow for complex publication dynamics. In particular, inferred topics are independent from each other –a publication about finance is assumed to have no influence on publications about politics, for instance. In this work, we develop the Multivariate Powered Dirichlet-Hawkes Process (MPDHP), that alleviates this assumption. Publications about various topics can now influence each other. We detail and overcome the technical challenges that arise from considering interacting topics. We conduct a systematic evaluation of MPDHP on a range of synthetic datasets to define its application domain and limitations. Finally, we develop a use case of the MPDHP on Reddit data.

Most previous works model up to two of those jointly, or rely on heavily parametric approaches.

It infers dynamic topic-dependent underlying diffusion networks in a continuous-time setting along with said topics. It is unsupervised; it considers an unlabeled stream of triplets shaped as (time of publication, information’s content, spreading entity) as input data.

This change especially affects exploratory information-seeking contexts, where conversational search systems can guide the discovery of unfamiliar domains. In these scenarios, users find it often difficult to express their information goals due to insufficient background knowledge. Conversational interfaces can provide assistance by eliciting information needs and narrowing down the search space. However, due to the complexity of information-seeking behavior, the design of conversational interfaces for retrieving information remains a great challenge. Although prior work has employed user studies to empirically ground the system design, most existing studies are limited to well-defined search tasks or known domains, thus being less exploratory in nature. Therefore, we conducted a laboratory study to investigate open-ended search behavior for navigation through unknown information landscapes. The study comprised of 26 participants who were restricted in their search to a text chat interface. Based on the collected dialogue transcripts, we applied statistical analyses and process mining techniques to uncover general information-seeking patterns across five different domains. We not only identify core dialogue acts and their interrelations that enable users to discover domain knowledge, but also derive design suggestions for conversational search systems.|对话式搜索已发展为一种新兴的信息检索范式,标志着从传统搜索系统向智能搜索代理交互对话的转变。这一变革尤其影响探索性信息查询场景,在此类场景中对话式搜索系统能够引导用户发现陌生领域。由于背景知识不足,用户在这些情境中往往难以准确表达信息目标。对话界面可通过需求澄清和搜索空间缩窄提供辅助,但由于信息寻求行为的复杂性,面向检索任务的对话界面设计仍存在巨大挑战。尽管先前研究通过用户实验为系统设计提供实证基础,但多数现有研究局限于目标明确的搜索任务或已知领域,本质上缺乏探索性。为此,我们开展了一项实验室研究,旨在考察开放式搜索行为在未知信息领域的导航过程。研究招募26名参与者,将其搜索行为限制在文本聊天界面内。基于收集的对话文本,我们运用统计分析流程挖掘技术,揭示了跨五个不同领域的通用信息寻求模式。不仅识别出使用户发现领域知识的核心对话行为及其相互关系,更为对话式搜索系统提出了具体的设计建议。

A recent advance in neural IR, COIL, extends this approach with contextualized inverted lists from a deep language model backbone and performs retrieval by comparing contextualized query-document term representation, which is effective but computationally expensive. This paper explores the effectiveness-efficiency tradeoff in COIL-style systems, aiming to reduce the computational complexity of retrieval while preserving term semantics. It proposes COILcr, which explicitly factorizes COIL into intra-context term importance weights and cross-context semantic representations. At indexing time, COILcr further maps term semantic representations to a smaller set of canonical representations. Experiments demonstrate that canonical representations can efficiently preserve term semantics, reducing the storage and computational cost of COIL-based retrieval while maintaining model performance. The paper also discusses and compares multiple heuristics for canonical representation selection and looks into its performance in different retrieval settings.|基于倒排索引的词项精确匹配系统是文本检索的基础架构。近期神经信息检索领域的重要进展COIL模型对此进行了扩展:通过深度语言模型构建上下文感知的倒排列表,在检索时比较查询-文档词项的上下文表征,虽然效果显著但计算成本高昂。本文探究COIL类系统的效果-效率权衡问题,旨在保持词项语义的同时降低检索计算复杂度。我们提出COILcr模型,将COIL显式分解为上下文内词项权重与跨上下文语义表征两个因子。在索引阶段,COILcr进一步将词项语义表征映射到更小的规范表征集合。实验表明规范表征能高效保持词项语义,在维持模型性能的同时显著降低基于COIL的检索存储与计算成本。本文还比较了多种规范表征选择的启发式方法,并探究了其在不同检索场景下的性能表现。|code|0| |Item Graph Convolution Collaborative Filtering for Inductive Recommendations|Edoardo D'Amico, Khalil Muhammad, Elias Z. Tragos, Barry Smyth, Neil Hurley, Aonghus Lawlor|Insight Centre for Data Analytics|Graph Convolutional Networks (GCN) have been recently employed as core component in the construction of recommender system algorithms, interpreting user-item interactions as the edges of a bipartite graph. However, in the absence of side information , the majority of existing models adopt an approach of randomly initialising the user embeddings and optimising them throughout the training process. This strategy makes these algorithms inherently transductive , curtailing their ability to generate predictions for users that were unseen at training time. To address this issue, we propose a convolution-based algorithm, which is inductive from the user perspective, while at the same time, depending only on implicit user-item interaction data. We propose the construction of an item-item graph through a weighted projection of the bipartite interaction network and to employ convolution to inject higher order associations into item embeddings, while constructing user representations as weighted sums of the items with which they have interacted. Despite not training individual embeddings for each user our approach achieves state-of-the-art recommendation performance with respect to transductive baselines on four real-world datasets, showing at the same time robust inductive performance.|图卷积网络(GCN)近期已成为推荐系统算法构建的核心组件,其将用户-物品交互关系视为二分图的边。然而,在缺乏辅助信息的情况下,现有模型大多采用随机初始化用户嵌入向量并通过训练过程持续优化的策略。这种方法使得算法本质上仅具备转导学习能力,无法为训练阶段未出现的用户生成预测。针对这一局限,我们提出了一种基于卷积的算法,该算法从用户视角看具有归纳学习特性,且仅依赖隐式的用户-物品交互数据。我们通过二分交互网络的加权投影构建物品-物品关系图,利用卷积操作将高阶关联信息注入物品嵌入表示,同时将用户表征构建为已交互物品的加权聚合。尽管未针对每个用户训练独立嵌入向量,我们的方法在四个真实数据集上的推荐性能超越了转导式基线模型,同时展现出强大的归纳学习能力。

Late interactions popularized by ColBERT and recently compressed with clustering in ColBERTv2 deliver state-of-the-art quality on many benchmarks. ColBERTv2 uses centroids along with occurrence-specific delta vectors to approximate contextualized embeddings without reducing ranking effectiveness. Analysis of this work suggests that these centroids are “term-topic embeddings”. We examine whether term-topic embeddings can be created in a differentiable end-to-end way, finding that this is a viable strategy for removing the separate clustering step. We investigate the importance of local context for contextualizing these term-topic embeddings, analogous to refining centroids with delta vectors. We find this end-to-end approach is sufficient for matching the effectiveness of the original contextualized embeddings.|基于Transformer模型的上下文表征显著提升了神经排序模型的性能。ColBERT提出的延迟交互机制及后续ColBERTv2通过聚类压缩的改进方案,已在多个基准测试中实现了最先进的检索效果。ColBERTv2采用质心向量与位置特定增量向量的组合来近似上下文嵌入,同时保持排序效能不减。分析表明这些质心向量实质上是"词项-主题嵌入"。本研究探讨了是否可通过可微分的端到端方式生成此类词项-主题嵌入,实验证明该策略能有效消除独立聚类步骤。我们进一步验证了局部上下文对于词项-主题嵌入情境化的重要性——其作用类似于通过增量向量优化质心。研究发现,这种端到端方法完全能够达到原始上下文嵌入的检索效果。

We systematically de-bias gold standard relevance judgement datasets with a set of balanced and well-matched query pairs. Such a de-biasing process will expose neural rankers to comparable queries from across gender identities that have associated relevant documents with compatible degrees of gender bias. Therefore, neural rankers will learn not to associate varying degrees of bias to queries from certain gender identities. Our experiments show that our approach is able to (1) systematically reduces gender biases associated with different gender identities, and (2) at the same time maintain the same level of retrieval effectiveness.|本文旨在证明,无需修改排序损失函数(当前文献采用的主流方法)即可显著降低神经排序模型中的刻板性别偏见。我们采用一组平衡且严格匹配的查询对,系统性消除了黄金标准相关性判定数据集中的偏见。这种去偏过程使神经排序模型能够接触来自不同性别身份的等效查询,这些查询关联的相关文档具有可比较的性别偏见程度。因此,神经排序模型将学会不对特定性别身份的查询关联不同程度的偏见。实验结果表明,我们的方法能够:(1) 系统性降低与不同性别身份相关的性别偏见;(2) 同时保持同等水平的检索效果。|code|0| |ColBERT-FairPRF: Towards Fair Pseudo-Relevance Feedback in Dense Retrieval|Thomas Jänich, Graham McDonald, Iadh Ounis|Univ Glasgow, Glasgow, Scotland|Pseudo-relevance feedback mechanisms have been shown to be useful in improving the effectiveness of search systems for retrieving the most relevant items in response to a user's query. However, there has been little work investigating the relationship between pseudo-relevance feedback and fairness in ranking. Indeed, using the feedback from an initial retrieval to revise a query can in principle also allow to optimise objectives beyond relevance, such as the fairness of the search results. In this work, we show how a feedback mechanism based on the successful ColBERT-PRF model can be used for retrieving fairer search results. Therefore, we propose a novel fair feedback mechanism for multiple representation dense retrieval (ColBERT-FairPRF), which enhances the distribution of exposure over groups of documents in the search results by fairly extracting the feedback embeddings that are added to the user's query representation. To fairly extract representative embeddings, we apply a clustering approach since traditional methods based on counting are not applicable in the dense retrieval space. Our results on the 2021 TREC Fair Ranking Track test collection demonstrate the effectiveness of our method compared to ColBERT-PRF, with statistical significant improvements of up to similar to 19% in AttentionWeighted Ranked Fairness. To the best of our knowledge, ColBERT-FairPRF is the first query expansion method for fairness in multiple representation dense retrieval.|伪相关反馈机制已被证实能有效提升搜索系统返回与用户查询最相关条目的性能。然而,关于伪相关反馈与排序公平性之间关系的研究却鲜有涉及。事实上,利用初始检索获得的反馈来修正查询,理论上还可实现相关性之外的目标优化——例如搜索结果的公平性。本研究展示了如何基于成功的ColBERT-PRF模型构建反馈机制以实现更公平的搜索结果检索。据此,我们提出了一种面向多元表示稠密检索的新型公平反馈机制(ColBERT-FairPRF),该机制通过公平提取待添加到用户查询表示中的反馈嵌入向量,从而优化搜索结果中文档群体的曝光分布。由于传统基于计数的方法不适用于稠密检索空间,我们采用聚类方法来实现代表性嵌入向量的公平提取。在2021年TREC公平排序赛道测试集上的实验表明,相比ColBERT-PRF,我们的方法能显著提升注意力加权排序公平性指标(最高提升约19%,具有统计显著性)。据我们所知,ColBERT-FairPRF是首个面向多元表示稠密检索的、以公平性为目标的查询扩展方法。

Eduardo Ares, Javier Parapar|Linknovate Science; University of A Coruña|Nowadays, search engine users commonly rely on query suggestions to improve their initial inputs. Current systems are very good at recommending lexical adaptations or spelling corrections to users’ queries. However, they often struggle to suggest semantically related keywords given a user’s query. The construction of a detailed query is crucial in some tasks, such as legal retrieval or academic search. In these scenarios, keyword suggestion methods are critical to guide the user during the query formulation. This paper proposes two novel models for the keyword suggestion task trained on scientific literature. Our techniques adapt the architecture of Word2Vec and FastText to generate keyword embeddings by leveraging documents’ keyword co-occurrence. Along with these models, we also present a specially tailored negative sampling approach that exploits how keywords appear in academic publications. We devise a ranking-based evaluation methodology following both known-item and ad-hoc search scenarios. Finally, we evaluate our proposals against the state-of-the-art word and sentence embedding models showing considerable improvements over the baselines for the tasks.|当前,搜索引擎用户普遍依赖查询建议来优化初始输入。现有系统在推荐词汇调整或拼写修正方面表现优异,但面对用户查询时往往难以推荐语义相关的关键词。在诸如法律检索或学术搜索等任务中,构建精确查询至关重要,此时关键词推荐方法对引导用户完成查询表述具有关键作用。本文针对科学文献训练场景提出了两种新颖的关键词推荐模型。我们的技术通过改进Word2Vec和FastText架构,利用文档关键词共现关系生成关键词嵌入表示。配合这些模型,我们还提出了一种专门设计的负采样方法,该方法深度挖掘了学术出版物中关键词的分布特征。我们遵循已知项目搜索和即席搜索两种场景,设计了一套基于排序的评估方案。最终实验表明,相较于最先进的词嵌入和句嵌入基线模型,我们的方案在任务性能上实现了显著提升。

In this work, we focus on the pointwise learning setting to compare the theoretical differences of both approaches and present a thorough empirical comparison on the prevalent semi-synthetic evaluation setup in unbiased learning-to-rank. We show theoretically that neural click models, similarly to IPS rankers, optimize for the true document relevance when the position bias is known.

Most of the previous methods have focused on a multi-stage ranking approach relying on query reformulation, a critical intermediate step that might lead to a sub-optimal retrieval. Other approaches have tried to use a fully neural IR first-stage, but are either zero-shot or rely on full learning-to-rank based on a dataset with pseudo-labels. In this work, leveraging the CANARD dataset, we propose an innovative lightweight learning technique to train a first-stage ranker based on SPLADE.

Existing work has shown that the conversational search paradigm can improve users' search experience in legal case retrieval with humans as intermediary agents. To move further towards a practical system, it is essential to decide what action a computer agent should take in conversational legal case retrieval. Existing works try to finish this task through Transformer-based models based on semantic information in open-domain scenarios. However, these methods ignore search behavioral information, which is one of the most important signals for understanding the information-seeking process and improving legal case retrieval systems. Therefore, we investigate the conversational agent action in legal case retrieval from the behavioral perspective. Specifically, we conducted a lab-based user study to collect user and agent search behavior while using agent-mediated conversational legal case retrieval systems. Based on the collected data, we analyze the relationship between historical search interaction behaviors and current agent actions in conversational legal case retrieval. We find that, with the increase of agent-user interaction behavioral indicators, agents are increasingly inclined to return results rather than clarify users' intent, but the probability of collecting candidates does not change significantly. With the increase of the interactions between the agent and the system, agents are more inclined to collect candidates than clarify users' intent and are more inclined to return results than collect candidates. We also show that the agent action prediction performance can be improved with both semantic and behavioral features. We believe that this work can contribute to a better understanding of agent action and useful guidance for developing practical systems for conversational legal case retrieval.|案件检索是一项专业的信息检索任务,旨在根据查询案例检索出支持性案例。现有研究表明,在以人类作为中介代理的对话式检索模式下,能够提升用户在案件检索中的搜索体验。为推进实用系统开发,关键在于确定计算机代理在对话式法律案例检索中应采取何种操作。现有研究主要基于开放域场景中Transformer模型的语义信息来完成该任务,但这些方法忽略了搜索行为信息——而行为信息正是理解信息获取过程和改进法律检索系统最重要的信号之一。为此,我们从行为视角探究法律案例检索中的对话代理行为。具体而言,我们通过实验室用户研究收集了用户在使用代理中介的对话式法律案例检索系统时与代理的搜索行为数据。基于收集的数据,我们分析了对话式法律案例检索中历史搜索交互行为与当前代理操作之间的关联。研究发现:随着代理-用户交互行为指标的增多,代理更倾向于返回结果而非澄清用户意图,但收集候选案例的概率变化不显著;随着代理-系统交互次数的增加,代理更倾向于收集候选案例而非澄清意图,且返回结果的操作显著多于收集候选案例。我们还证明,结合语义特征和行为特征可提升代理行为预测性能。相信本研究成果有助于深化对代理行为的理解,并为开发实用的对话式法律案例检索系统提供有效指导。|code|0| |Entity Embeddings for Entity Ranking: A Replicability Study|Pooja Oza, Laura Dietz|University of New Hampshire|Knowledge Graph embeddings model semantic and structural knowledge of entities in the context of the Knowledge Graph.

Adapters are memory-efficient and scale well with downstream tasks by training small bottle-neck layers added between transformer layers while keeping the large pretrained language model (PLMs) frozen. In spite of showing promising results in NLP, these methods are under-explored in Information Retrieval. While previous studies have only experimented with dense retriever or in a cross lingual retrieval scenario, in this paper we aim to complete the picture on the use of adapters in IR. First, we study adapters for SPLADE, a sparse retriever, for which adapters not only retain the efficiency and effectiveness otherwise achieved by finetuning, but are memory-efficient and orders of magnitude lighter to train. We observe that Adapters-SPLADE not only optimizes just 2% of training parameters, but outperforms fully fine-tuned counterpart and existing parameter-efficient dense IR models on IR benchmark datasets. Secondly, we address domain adaptation of neural retrieval thanks to adapters on cross-domain BEIR datasets and TripClick. Finally, we also consider knowledge sharing between rerankers and first stage rankers. Overall, our study complete the examination of adapters for neural IR.

A personalized chatbot is considered to have a consistent personality. There are two types of methods to learn the personality. The first mainly model the personality from explicit user profiles ( e.g. , manually created persona descriptions). The second learn implicit user profiles from the user’s dialogue history, which contains rich, personalized information. However, a user’s dialogue history can be long and noisy as it contains long-time, multi-topic historical dialogue records. Such data noise and redundancy impede the model’s ability to thoroughly and faithfully learn a consistent personality, especially when applied with models that have an input length limit ( e.g. , BERT). In this paper, we propose deconstructing the long and noisy dialogue history into topic-dependent segments. We only use the topically related dialogue segment as context to learn the topic-aware user personality. Specifically, we design a Top ic-enhanced personalized R etrieval-based C hatbot, TopReC. It first deconstructs the dialogue history into topic-dependent dialogue segments and filters out irrelevant segments to the current query via a Heter-Merge-Reduce framework. It then measures the matching degree between the response candidates and the current query conditioned on each topic-dependent segment. We consider the matching degree between the response candidate and the cross-topic user personality. The final matching score is obtained by combining the topic-dependent and cross-topic matching scores. Experimental results on two large dataset show that TopReC outperforms all previous state-of-the-art methods.|构建个性化聊天机器人近来备受关注。一个优秀的个性化聊天机器人应当具备稳定的性格特征。目前学习用户性格的方法主要分为两类:第一类通过显式用户画像(如人工创建的人物描述)建模性格;第二类则从用户对话历史中学习隐式用户画像,这些历史对话蕴含丰富的个性化信息。然而,用户对话历史往往存在冗长和噪声问题,因其包含跨时段、多主题的历史对话记录。此类数据噪声与冗余会阻碍模型全面、准确地学习一致性人格特征,尤其当采用存在输入长度限制的模型(如BERT)时更为明显。

本文提出将冗长嘈杂的对话历史解构为基于主题的对话片段,仅使用主题相关的对话片段作为上下文来学习主题感知的用户性格。具体而言,我们设计了一种基于主题增强的个性化检索式聊天机器人TopReC。该系统首先通过异质融合-精简框架(Heter-Merge-Reduce)将对话历史解构为主题相关对话片段,并过滤与当前查询无关的片段;随后计算各候选回复在当前主题相关片段条件下与查询的匹配度;同时考量候选回复与跨主题用户性格特征的匹配程度。最终通过融合主题相关匹配分数与跨主题匹配分数获得综合评分。在两个大型数据集上的实验结果表明,TopReC超越了所有现有最优方法。

Specifically, we combine standard and transformer-based methods to extract entities (e.g., drugs, medical problems), disambiguate their meaning (e.g., family history, negations), or expand them with related medical concepts to synthesize diverse query representations. The empirical evaluation showed that certain query representations positively affect retrieval effectiveness for patient allocation in clinical trials, but no statistically significant improvements have been identified in medical literature retrieval. Across the queries, it has been found that removing negated entities using a domain-specific pre-trained transformer model has been more effective than a standard rule-based approach. In addition, our experiments have shown that removing information related to family history can further improve patient allocation in clinical trials.|本研究探讨了从非结构化临床笔记中提取的各类患者相关信息对两项不同任务的影响:临床试验患者分配和医学文献检索。具体而言,我们结合标准方法与基于Transformer的方法来提取实体(如药物、医疗问题)、消歧其含义(如家族史、否定表达)或通过关联医学术语进行概念扩展,从而构建多样化的查询表征。实证评估表明,特定查询表征能有效提升临床试验患者分配的检索效果,但在医学文献检索任务中未观察到统计学上的显著改进。通过跨查询分析发现,采用领域特定的预训练Transformer模型去除否定实体比传统基于规则的方法更为有效。此外,实验结果表明剔除家族史相关信息可进一步优化临床试验中的患者分配效果。

One way to alleviate this problem is to leverage knowledge from relevant domains. In this paper, we focus on an important real-world scenario in which some users overlap two different domains but items of the two domains are distinct. Although several studies leverage side information (e.g., user reviews) for cross-domain recommendation, side information is not always available or easy to obtain in practice. To this end, we propose cross-domain preference ranking (CPR) with a simple yet effective user transformation that leverages only user interactions with items in the source and target domains to transform the user representation. Given the proposed user transformation, CPR not only successfully enhances recommendation performance for users having interactions with target-domain items but also yields superior performance for cold-start users in comparison with state-of-the-art cross-domain recommendation approaches. Extensive experiments conducted on three pairs of cross-domain recommendation datasets demonstrate the effectiveness of the proposed method in comparison with existing cross-domain recommendation approaches.

They are, however, prone to inefficiency due to factors such as differing knowledge among participants. The research goal of this paper is to design a recommendation-based meeting assistant that can improve the efficiency of meetings by helping to contextualize the information being discussed and reduce distractions for listeners. Following a Wizard-of-Oz setup, we gathered user feedback by thematically analyzing focus group discussions and identifying this kind of system’s key challenges and requirements. The findings point to shortcomings in contextualization and raise concerns about distracting listeners from the main content.

While Neural Information Retrieval (IR) methods have provided state-of-the-art results for matching queries to documents, they have not been extended to the task of Reviewed-Item Retrieval (RIR), where query-review scores must be aggregated (or fused) into item-level scores for ranking. In the absence of labeled RIR datasets, we extend Neural IR methodology to RIR by leveraging self-supervised methods for contrastive learning of BERT embeddings for both queries and reviews. Specifically, contrastive learning requires a choice of positive and negative samples, where the unique two-level structure of our item-review data combined with meta-data affords us a rich structure for the selection of these samples. For contrastive learning in a Late Fusion scenario (where we aggregate query-review scores into item-level scores), we investigate the use of positive review samples from the same item and/or with the same rating, selection of hard positive samples by choosing the least similar reviews from the same anchor item, and selection of hard negative samples by choosing the most similar reviews from different items. We also explore anchor sub-sampling and augmenting with meta-data. For a more end-to-end Early Fusion approach, we introduce contrastive item embedding learning to fuse reviews into single item embeddings. Experimental results show that Late Fusion contrastive learning for Neural RIR outperforms all other contrastive IR configurations, Neural IR, and sparse retrieval baselines, thus demonstrating the power of exploiting the two-level structure in Neural RIR approaches as well as the importance of preserving the nuance of individual review content via Late Fusion methods.|随着自然语言界面使用户能够表达日益复杂的自然语言查询,用户评论内容也呈现出爆发式增长,这有助于用户更精准地匹配餐厅、书籍或电影等符合其复杂查询需求的条目。尽管神经信息检索(IR)方法在查询-文档匹配任务中已取得最先进的成果,但尚未推广至评论-条目检索(RIR)任务——该任务需要将查询-评论匹配分数聚合(或融合)为条目级评分以供排序。在缺乏标注RIR数据集的情况下,我们通过自监督方法扩展神经IR技术至RIR领域,采用对比学习机制分别训练查询和评论的BERT嵌入向量。

具体而言,对比学习需要选择正负样本,而我们的条目-评论数据特有的双层结构结合元数据,为此类样本选择提供了丰富的结构化基础。针对"延迟融合"场景(将查询-评论分数聚合为条目级分数)的对比学习,我们研究采用以下策略:选择同条目和/或同评分的评论作为正样本;通过选取锚点条目中最不相似的评论构建困难正样本;通过选择不同条目中最相似的评论构建困难负样本。同时我们还探索了锚点子采样及元数据增强技术。对于更端到端的"早期融合"方法,我们提出对比式条目嵌入学习,将多条评论融合为单一条目嵌入向量。

实验结果表明:神经RIR的延迟融合对比学习方案在性能上超越所有其他对比IR配置、传统神经IR以及稀疏检索基线方法。这既验证了利用双层结构特征对神经RIR方法的显著增益,也证明了通过延迟融合保留个体评论内容细微差异的重要性。|code|0| |Exploiting Graph Structured Cross-Domain Representation for Multi-domain Recommendation|Alejandro ArizaCasabona, Bartlomiej Twardowski, Tri Kurniawan Wijaya|UAB, Comp Vis Ctr, Barcelona, Spain; Univ Barcelona, Barcelona, Spain; Huawei Ireland Res Ctr, Dublin, Ireland|Multi-domain recommender systems benefit from cross-domain representation learning and positive knowledge transfer. Both can be achieved by introducing a specific modeling of input data (i.e. disjoint history) or trying dedicated training regimes. At the same time, treating domains as separate input sources becomes a limitation as it does not capture the interplay that naturally exists between domains. In this work, we efficiently learn multi-domain representation of sequential users' interactions using graph neural networks. We use temporal intra- and inter-domain interactions as contextual information for our method called MAGRec (short for Multi-domAin Graph-based Recommender). To better capture all relations in a multi-domain setting, we learn two graph-based sequential representations simultaneously: domain-guided for recent user interest, and general for long-term interest. This approach helps to mitigate the negative knowledge transfer problem from multiple domains and improve overall representation. We perform experiments on publicly available datasets in different scenarios where MAGRec consistently outperforms state-of-the-art methods. Furthermore, we provide an ablation study and discuss further extensions of our method.|多领域推荐系统受益于跨领域表征学习和正向知识迁移。这两种机制既可以通过对输入数据(即离散历史记录)进行特定建模来实现,也可以尝试采用专门的训练策略。然而,将不同领域视为独立输入源的做法存在局限性,因其无法捕捉领域间天然存在的交互关系。本研究创新性地利用图神经网络高效学习用户序列交互的多领域表征。我们提出的MAGRec(多领域图推荐系统)方法将时序性领域内与跨领域交互作为上下文信息。为了更好地捕捉多领域环境中的所有关联关系,我们同步学习两种基于图的序列表征:领域引导表征(反映近期用户兴趣)和通用表征(反映长期兴趣)。该方案能有效缓解多领域带来的负向知识迁移问题,并提升整体表征质量。我们在多种场景下的公开数据集上进行实验,结果表明MAGRec持续超越现有最优方法。此外,本文还提供了消融实验分析,并探讨了该方法的潜在扩展方向。|code|0| |Graph-Based Recommendation for Sparse and Heterogeneous User Interactions|Simone Borg Bruun, Kacper Kenji Lesniak, Mirko Biasini, Vittorio Carmignani, Panagiotis Filianos, Christina Lioma, Maria Maistro|FullBrain; University of Copenhagen|Recommender system research has oftentimes focused on approaches that operateon large-scale datasets containing millions of user interactions.

A popular approach for post-hoc interpretability text ranking models are based on locally approximating the model behavior using a simple ranker. Since rankings have multiple relevance factors and are aggregations of predictions, existing approaches that use a single ranker might not be sufficient to approximate a complex model, resulting in low fidelity. In this paper, we overcome this problem by considering multiple simple rankers to better approximate the entire ranking list from a black-box ranking model. We pose the problem of local approximation as a GENERALIZED PREFERENCE COVERAGE (GPC) problem that incorporates multiple simple rankers towards the listwise explanation of ranking models. Our method MULTIPLEX uses a linear programming approach to judiciously extract the explanation terms, so that to explain the entire ranking list. We conduct extensive experiments on a variety of ranking models and report fidelity improvements of 37%-54% over existing competitors.

Biased query suggestions can be especially problematic if a user’s information need is not set and the interaction with query suggestions is likely. Only recently, research has started to investigate the general assumption that biased search queries lead to biased search results, focusing on political stance bias [17].

It has been widely applied in a variety of downstream tasks, e.g., information retrieval and question answering. The most recent works of STM leverage Pre-trained Language Models (abbr., PLMs) due to their remarkable capacity for representation learning. Accordingly, significant improvements have been achieved. However, our findings show that PLMs fail to capture task-specific features that signal hardly-perceptible changes in semantics. To overcome the issue, we propose a two-channel Feature Differentiation and Fusion network (FDF). It utilizes a PLM-based encoder to extract features separately from the unabridged texts and those abridged by deduplication. On this basis, gated feature fusion and interaction are conducted across the channels to expand text representations with attentive and distinguishable features. Experiments on the benchmarks QQP, MRPC and BQ show that FDF obtains substantial improvements compared to the baselines and outperforms the state-of-the-art STM models.|语义文本匹配(简称STM)是指自动判定文本对之间语义相似度的任务。该技术已广泛应用于信息检索、问答系统等多种下游场景。当前最先进的STM方法主要采用预训练语言模型(PLM),因其具有卓越的表示学习能力,并由此取得了显著性能提升。然而本研究发现,PLM难以捕捉那些表征细微语义变化的任务特异性特征。为此,我们提出双通道特征分化融合网络(FDF):通过基于PLM的编码器分别从完整文本和经去重处理的精简文本中提取特征,在此基础上进行跨通道的门控特征融合与交互,利用具有注意力机制的可区分性特征来扩展文本表示。在QQP、MRPC和BQ基准数据集上的实验表明,FDF相较基线模型取得显著提升,其性能优于当前最先进的STM模型。

However, existing anomaly detection models on e-commerce platforms face the challenges of “cold-start” and heterogeneous graphs which contain multiple types of nodes and edges. The scarcity of labeled anomalous training samples on heterogeneous graphs hinders the training of reliable models for anomaly detection.

To this end, we propose a D omain A daptation method for heterogeneous GR aph A nomaly D etection in E -commerce ( DAGrade ).

The ItemKNN algorithm with conditional probability-inspired similarity function has a hyperparameter $$\alpha $$ that allows one to counteract this popularity bias. In this work, we perform a deep dive into the effects of this hyperparameter in both online and offline experiments, with regard to both accuracy metrics and equality of exposure. Our experiments show that the hyperparameter can indeed counteract popularity bias in a dataset. We also find that there exists a trade-off between countering popularity bias and the quality of the recommendations: Reducing popularity bias too much results in a decrease in click-through rate, but some counteracting of popularity bias is required for optimal online performance.|若不采取相应措施,协同过滤技术往往会放大训练数据中存在的流行度偏差。基于条件概率相似度函数的ItemKNN算法通过超参数$$\alpha$$提供了抑制这种流行度偏差的调节机制。本研究通过线上和线下实验,从推荐准确性指标和曝光均衡性两个维度深入探究了该超参数的影响机制。实验结果表明:该超参数能有效抑制数据集中的流行度偏差;同时发现抑制流行度偏差与推荐质量之间存在权衡关系——过度削弱流行度偏差会导致点击率下降,但适度的偏差抑制是实现最优线上性能的必要条件。

It was shown in prior work that interpolation between the relevance score of lexical and BERT-based re-rankers may not consistently result in higher effectiveness. Our idea is motivated by the finding that BERT models can capture numeric information. We compare several representations of the BM25 score and inject them as text in the input of four different cross-encoders. We additionally analyze the effect for different query types, and investigate the effectiveness of our method for capturing exact matching relevance. Evaluation on the MSMARCO Passage collection and the TREC DL collections shows that the proposed method significantly improves over all cross-encoder re-rankers as well as the common interpolation methods. We show that the improvement is consistent for all query types. We also find an improvement in exact matching capabilities over both BM25 and the cross-encoders. Our findings indicate that cross-encoder re-rankers can efficiently be improved without additional computational burden and extra steps in the pipeline by explicitly adding the output of the first-stage ranker to the model input, and this effect is robust for different models and query types.|本文提出了一种融合一阶段词汇检索模型与基于Transformer的重排序器的新颖方法:我们将词汇模型的相关性分数以标记形式注入到交叉编码器重排序器输入的中间位置。已有研究表明,词汇模型与基于BERT的重排序器的相关性分数插值法并不总能稳定提升效果。本方法的灵感来源于BERT模型能够捕获数值信息的发现。我们比较了BM25分数的多种表示形式,并将其作为文本注入四种不同交叉编码器的输入中。此外,我们分析了该方法对不同查询类型的影响,并探究了其在精确匹配相关性捕获方面的有效性。在MSMARCO段落数据集和TREC DL数据集上的实验表明,该方法显著优于所有交叉编码器重排序器及常见插值方法。实证结果显示,该改进对所有查询类型均具有一致性。我们还发现该方法在精确匹配能力上同时超越了BM25和交叉编码器。研究结果表明,通过将一阶段排序器的输出显式添加至模型输入端,无需额外计算负担或流程步骤即可有效提升交叉编码器重排序器的性能,且该效果在不同模型和查询类型间均保持稳健。|code|0| |Market-Aware Models for Efficient Cross-Market Recommendation|Samarth Bhargav, Mohammad Aliannejadi, Evangelos Kanoulas|University of Amsterdam|We consider the cross-market recommendation (CMR) task, which involves recommendation in a low-resource target market using data from a richer, auxiliary source market. Prior work in CMR utilised meta-learning to improve recommendation performance in target markets; meta-learning however can be complex and resource intensive. In this paper, we propose market-aware (MA) models, which directly model a market via market embeddings instead of meta-learning across markets. These embeddings transform item representations into market-specific representations. Our experiments highlight the effectiveness and efficiency of MA models both in a pairwise setting with a single target-source market, as well as a global model trained on all markets in unison. In the former pairwise setting, MA models on average outperform market-unaware models in 85% of cases on nDCG@10, while being time-efficient - compared to meta-learning models, MA models require only 15% of the training time. In the global setting, MA models outperform market-unaware models consistently for some markets, while outperforming meta-learning-based methods for all but one market. We conclude that MA models are an efficient and effective alternative to meta-learning, especially in the global setting.|我们研究跨市场推荐(CMR)任务,该任务旨在利用资源丰富的辅助源市场数据来提升资源匮乏目标市场的推荐效果。现有CMR研究多采用元学习方法来提升目标市场推荐性能,但元学习往往复杂度高且资源消耗大。本文提出市场感知(MA)模型,该方法通过市场嵌入向量直接建模市场特征,而非采用跨市场的元学习策略。这些嵌入向量能将项目表示转换为特定市场的表征形式。实验结果表明,无论是在单目标-源市场配对场景,还是在所有市场联合训练的全局模型中,MA模型均展现出卓越的效能与效率。在配对场景下,MA模型在85%的案例中nDCG@10指标优于无视市场差异的基准模型,同时具有显著时间效率优势——相较元学习模型,MA模型仅需15%的训练时间。在全局设置中,MA模型在某些市场持续优于无视市场差异的模型,且在除一个市场外的所有案例中都超越基于元学习的方法。我们得出结论:MA模型是替代元学习的高效方案,尤其在全局设置中表现尤为突出。

However, although GCN shows powerful feature extraction capability in user-item bipartite graphs, the GCN-based methods appear powerless for knowledge graph (KG) with complex structures and rich information. In addition, all of the existing GCN-based recommendation systems suffer from the over-smoothing problem, which results in the models not being able to utilize higher-order neighborhood information, and thus these models always achieve their best performance at shallower layers. In this paper, we propose a Deep Light Graph Convolution Network for Knowledge Graph (KDL-GCN) to alleviate the above limitations. Firstly, the User-Entity Bipartite Graph approach (UE-BP) is proposed to simplify knowledge graph, which leverages entity information by constructing multiple interaction graphs. Secondly, a Deep Light Graph Convolution Network (DLGCN) is designed to make full use of higher-order neighborhood information. Finally, experiments on three real-world datasets show that the KDL-GCN proposed in this paper achieves substantial improvement compared to the state-of-the-art methods.|近年来,基于图卷积网络(GCN)的推荐算法因其能学习更高效的节点嵌入而取得了诸多突破性成果。然而,尽管GCN在用户-项目二分图中展现出强大的特征提取能力,但面对结构复杂且信息丰富的知识图谱(KG)时,现有基于GCN的方法仍显乏力。此外,当前所有基于GCN的推荐系统都存在过度平滑问题,导致模型无法有效利用高阶邻域信息,因而这些模型通常在较浅层数时就达到性能峰值。本文提出面向知识图谱的深度轻量图卷积网络(KDL-GCN)以解决上述局限:首先设计用户-实体二分图方法(UE-BP)通过构建多重交互图来简化知识图谱并有效利用实体信息;其次构建深度轻量图卷积网络(DLGCN)以充分挖掘高阶邻域信息;最终在三个真实场景数据集上的实验表明,本文提出的KDL-GCN相较现有最优方法实现了显著性能提升。

While progress has been made on Cross Language IR (CLIR) where queries are expressed in one language and documents in another, the multilingual (MLIR) task to create a single ranked list of documents across many languages is considerably more challenging. This paper investigates whether advances in neural document translation and pretrained multilingual neural language models enable improvements in the state of the art over earlier MLIR techniques. The results show that although combining neural document translation with neural ranking yields the best Mean Average Precision (MAP), 98% of that MAP score can be achieved with an 84% reduction in indexing time by using a pretrained XLM-R multilingual language model to index documents in their native language, and that 2% difference in effectiveness is not statistically significant.

In structured document retrieval (SDR), BM25F could be considered the most established model. However, without optimization BM25F does not benefit from the document structure. The main contribution of this paper is a new field weighting method, denoted Information Content Field Weighting (ICFW). It applies weights over the structure without optimization and overcomes issues faced by some existing SDR models, most notably the issue of saturating term frequency across fields. ICFW is similar to BM25 and LM in its analytical grounding and transparency, making it a potential new candidate for a standard SDR model. For an optimised retrieval scenario ICFW does as well, or better than baselines. More interestingly, for a non-optimised retrieval scenario we observe a considerable increase in performance. Extensive analysis is performed to understand and explain the underlying reasons for this increase.|在原子检索领域,BM25和语言模型(LM)等概率模型已成为业界标准。对于结构化文档检索(SDR)而言,BM25F可被视为当前最成熟的模型。但未经优化时,BM25F无法有效利用文档结构信息。本文的核心贡献是提出了一种新型字段加权方法——信息量字段加权(ICFW)。该方法无需优化即可实现结构化加权,并解决了现有部分SDR模型(尤其是跨字段词频饱和问题)的固有缺陷。ICFW在理论基础和算法透明度方面与BM25及LM一脉相承,有望成为SDR领域的新基准模型。实验表明:在优化检索场景下,ICFW达到或超越基线性能;更值得注意的是,在非优化场景中其性能提升尤为显著。我们通过深入分析揭示了这一性能提升的内在机理。

Unfortunately, SRs are labor-intensive and unscalable with the exponential growth in literature. Automating evidence synthesis using machine learning models has been proposed but solely focuses on the text and ignores additional features like citation information. Recent work demonstrated that citation embeddings can outperform the text itself, suggesting that better network representation may expedite SRs. Yet, how to utilize the rich information in heterogeneous information networks (HIN) for network embeddings is understudied. Existing HIN models fail to produce a high-quality embedding compared to simply running state-of-the-art homogeneous network models. To address existing HIN model limitations, we propose SR-CoMbEr, a community-based multi-view graph convolutional network for learning better embeddings for evidence synthesis. Our model automatically discovers article communities to learn robust embeddings that simultaneously encapsulate the rich semantics in HINs.

However, it is still unclear to what extent such approaches generalize in zero-shot conditions. The recent BEIR benchmark provides partial answers to this question by comparing models on datasets and tasks that differ from the training conditions. We aim to address the same question by comparing models under more explicit distribution shifts. To this end, we build three query-based distribution shifts within MS MARCO (query-semantic, query-intent, query-length), which are used to evaluate the three main families of neural retrievers based on BERT: sparse, dense, and late-interaction - as well as a monoBERT re-ranker. We further analyse the performance drops between the train and test query distributions. In particular, we experiment with two generalization indicators: the first one based on train/test query vocabulary overlap, and the second based on representations of a trained bi-encoder. Intuitively, those indicators verify that the further away the test set is from the train one, the worse the drop in performance. We also show that models respond differently to the shifts - dense approaches being the most impacted. Overall, our study demonstrates that it is possible to design more controllable distribution shifts as a tool to better understand generalization of IR models. Finally, we release the MS MARCO query subsets, which provide an additional resource to benchmark zero-shot transfer in Information Retrieval.|预训练语言模型近来在信息检索领域崭露头角,成为新一代神经系统的核心架构,在多项任务中超越传统方法。然而,此类方法在零样本条件下的泛化能力仍不明确。近期推出的BEIR基准测试通过比较模型在不同于训练条件的数据集和任务上的表现,为该问题提供了部分答案。我们旨在通过更显式的分布偏移对比,进一步探究这一问题。为此,我们在MS MARCO数据集内构建了三种基于查询的分布偏移(查询语义偏移、查询意图偏移、查询长度偏移),用于评估基于BERT的三大神经检索模型家族:稀疏检索、稠密检索和延迟交互式检索,以及monoBERT重排序器。我们进一步分析了训练集与测试集查询分布间的性能落差,特别通过两种泛化指标进行实验验证:第一种基于训练/测试查询词汇重叠度,第二种基于训练好的双编码器表征。直观来看,这些指标证实测试集与训练集的偏离程度越大,性能下降越显著。我们还发现不同模型对分布偏移的响应存在差异——其中稠密检索方法受影响最大。总体而言,本研究证明通过设计更可控的分布偏移,可以将其作为理解信息检索模型泛化能力的有效工具。最后,我们发布了MS MARCO查询子集,为零样本迁移在信息检索中的基准测试提供了新的资源。|code|0| |Improving Video Retrieval Using Multilingual Knowledge Transfer|Avinash Madasu, Estelle Aflalo, Gabriela Ben Melech Stan, ShaoYen Tseng, Gedas Bertasius, Vasudev Lal|University of North Carolina at Chapel Hill; Intel Labs|Multi-modal retrieval has seen tremendous progress with the development of vision-language models. However, further improving these models require additional labelled data which is a huge manual effort. In this paper, we propose a framework MuMUR, that utilizes knowledge transfer from a multilingual model to boost the performance of multi-modal (image and video) retrieval. We first use state-of-the-art machine translation models to construct pseudo ground-truth multilingual visual-text pairs. We then use this data to learn a joint vision-text representation where English and non-English text queries are represented in a common embedding space based on pretrained multilingual models. We evaluate our proposed approach on a diverse set of retrieval datasets: five video retrieval datasets such as MSRVTT, MSVD, DiDeMo, Charades and MSRVTT multilingual, two image retrieval datasets such as Flickr30k and Multi30k . Experimental results demonstrate that our approach achieves state-of-the-art results on all video retrieval datasets outperforming previous models. Additionally, our framework MuMUR significantly beats other multilingual video retrieval dataset. We also observe that MuMUR exhibits strong performance on image retrieval. This demonstrates the universal ability of MuMUR to perform retrieval across all visual inputs (image and video) and text inputs (monolingual and multilingual).|多模态检索技术随着视觉-语言模型的进步取得了显著发展。然而,要进一步优化这些模型需要额外标注数据,这需要耗费巨大人工成本。本文提出MuMUR框架,通过迁移多语言模型的知识来提升多模态(图像与视频)检索性能。我们首先采用前沿机器翻译模型构建伪真实值的多语言视觉-文本配对数据,随后利用该数据学习联合视觉-文本表征,使英语与非英语文本查询能基于预训练多语言模型在统一嵌入空间中表示。我们在多样化检索数据集上评估该方法:包括MSRVTT、MSVD、DiDeMo、Charades和MSRVTT多语言版五个视频检索数据集,以及Flickr30k和Multi30k两个图像检索数据集。实验结果表明,我们的方法在所有视频检索数据集上都达到了最先进水平,超越了先前模型。特别值得注意的是,MuMUR框架在多语言视频检索数据集上的表现显著优于其他方法。同时我们发现MuMUR在图像检索任务中也展现出强劲性能,这证明了该框架具备跨视觉输入(图像与视频)和文本输入(单语与多语)的通用检索能力。

Nguyen, Cathal Gurrin|Dublin City University; VNU-HCM, University of Science|Many models have been proposed for vision and language tasks, especially the image-text retrieval task. State-of-the-art (SOTA) models in this challenge contain hundreds of millions of parameters. They also were pretrained on large external datasets that have been proven to significantly improve overall performance. However, it is not easy to propose a new model with a novel architecture and intensively train it on a massive dataset with many GPUs to surpass many SOTA models already available to use on the Internet. In this paper, we propose a compact graph-based framework named HADA, which can combine pretrained models to produce a better result rather than starting from scratch. Firstly, we created a graph structure in which the nodes were the features extracted from the pretrained models and the edges connecting them. The graph structure was employed to capture and fuse the information from every pretrained model. Then a graph neural network was applied to update the connection between the nodes to get the representative embedding vector for an image and text. Finally, we employed cosine similarity to match images with their relevant texts and vice versa to ensure a low inference time. Our experiments show that, although HADA contained a tiny number of trainable parameters, it could increase baseline performance by more than $$3.6%$$ in terms of evaluation metrics on the Flickr30k dataset. Additionally, the proposed model did not train on any external dataset and only required a single GPU to train due to the small number of parameters required.

We posit that a robust CMR model should generalize well across both dataset types. Despite recent advances in CMR, the reproducibility of the results and their generalizability across different dataset types has not been studied before. We address this gap and focus on the reproducibility of the state-of-the-art CMR results when evaluated on object-centric and scene-centric datasets. We select two state-of-the-art CMR models with different architectures: (i) CLIP; and (ii) X-VLM. Additionally, we select two scene-centric datasets, and three object-centric datasets, and determine the relative performance of the selected models on these datasets. We focus on reproducibility, replicability, and generalizability of the outcomes of previously published CMR experiments. We discover that the experiments are not fully reproducible and replicable. Besides, the relative performance results partially generalize across object-centric and scene-centric datasets. On top of that, the scores obtained on object-centric datasets are much lower than the scores obtained on scene-centric datasets.

The generation and exploitation of clarifying questions is an emerging area of research in information retrieval, especially in the context of conversational search. In this paper, we attempt to reproduce and analyse a milestone work in this area. Through close communication with the original authors and data sharing, we were able to identify a key issue that impacted the original experiments and our independent attempts at reproduction; this issue relates to data preparation. In particular, the clarifying questions retrieval task consists of retrieving clarifying questions from a question bank for a given query. In the original data preparation, such question bank was split into separate folds for retrieval – each split contained (approximately) a fifth of the data in the full question bank. This setting does not resemble that of a production system; in addition, it also was only applied to learnt methods, while keyword matching methods used the full question bank. This created inconsistency in the reporting of the results and overestimated findings.

In this reproducibility study, we revisit query batching in the context of large-scale conjunctive processing over inverted indexes, considering both on-disk and in-memory index arrangements.

Many LSR methods have been recently introduced, with Splade models achieving state-of-the-art performance on MSMarco. Despite similarities in their model architectures, many LSR methods show substantial differences in effectiveness and efficiency. Differences in the experimental setups and configurations used make it difficult to compare the methods and derive insights. In this work, we analyze existing LSR methods and identify key components to establish an LSR framework that unifies all LSR methods under the same perspective. We then reproduce all prominent methods using a common codebase and re-train them in the same environment, which allows us to quantify how components of the framework affect effectiveness and efficiency. We find that (1) including document term weighting is most important for a method’s effectiveness, (2) including query weighting has a small positive impact, and (3) document expansion and query expansion have a cancellation effect. As a result, we show how removing query expansion from a state-of-the-art model can reduce latency significantly while maintaining effectiveness on MSMarco and TripClick benchmarks.

In this paper we analyze with a replicability study if the lessons learned generalize to the retrieval of responses for dialogues, an important task for the increasingly popular field of conversational search. Unlike passage and document retrieval where documents are usually longer than queries, in response ranking for dialogues the queries (dialogue contexts) are often longer than the documents (responses). Additionally, dialogues have a particular structure, i.e. multiple utterances by different users. With these differences in mind, we here evaluate how generalizable the following major findings from previous works are: (F1) query expansion outperforms a no-expansion baseline; (F2) document expansion outperforms a no-expansion baseline; (F3) zero-shot dense retrieval underperforms sparse baselines; (F4) dense retrieval outperforms sparse baselines; (F5) hard negative sampling is better than random sampling for training dense models.

While these methods, such as the Dense Passage Retriever (DPR), work well on datasets or domains they have been trained on, there is a noticeable loss in accuracy when tested on out-of-distribution and out-of-domain datasets. We hypothesize that this may be, in large part, due to the mismatch in the information available to the context encoder and the query encoder during training. Most training datasets commonly used for training dense retrieval models contain an overwhelming majority of passages where there is only one query from a passage. We hypothesize that this imbalance encourages dense retrieval models to overfit to a single potential query from a given passage leading to worse performance on out-of-distribution and out-of-domain queries. To test this hypothesis, we focus on a prominent dense retrieval method, the dense passage retriever, build generated datasets that have multiple queries for most passages, and compare dense passage retriever models trained on these datasets against models trained on single query per passage datasets. Using the generated datasets, we show that training on passages with multiple queries leads to models that generalize better to out-of-distribution and out-of-domain test datasets.|在开放域检索任务中,密集检索方法已超越传统稀疏检索方法。尽管如密集段落检索器(DPR)等方法在训练数据集或领域内表现良好,但当测试数据来自分布外(out-of-distribution)或跨域(out-of-domain)时,其准确率会出现显著下降。我们认为这种现象很大程度上源于训练阶段上下文编码器与查询编码器可用信息的不匹配。当前用于训练密集检索模型的数据集中,绝大多数段落仅对应单一查询,这种不平衡性会促使模型过度拟合段落与特定查询的单一映射关系,从而导致对分布外和跨域查询的泛化性能下降。为验证该假设,我们选取代表性密集检索方法DPR作为研究对象,构建了多数段落对应多重查询的生成数据集,并将基于此训练的模型与单查询数据集训练的模型进行对比。实验结果表明,采用多查询段落进行训练能使模型在分布外和跨域测试数据集上展现出更强的泛化能力。

However, such spatio-temporal data are typically extracted in the form of a continuous skeleton sequence without any information about semantic segmentation or annotation. To make the extracted data reusable for further processing, there is a need to access them based on their content. In this paper, we introduce a universal retrieval approach that compares any two skeleton sequences based on temporal order and similarities of their underlying segments. The similarity of segments is determined by their content-preserving low-dimensional code representation that is learned using the Variational AutoEncoder principle in an unsupervised way. The quality of the proposed representation is validated in retrieval and classification scenarios; our proposal outperforms the state-of-the-art approaches in effectiveness and reaches speed-ups up to 64x on common skeleton sequence datasets.|近期姿态估计方法的进展使得从普通视频中提取高精度三维人体骨骼数据成为可能,这为广泛的应用场景带来了巨大机遇。然而,这类时空数据通常以连续骨骼序列的形式提取,缺乏语义分割或标注信息。为使提取的数据能有效复用,需要建立基于内容的检索机制。本文提出一种通用检索方法,通过比较骨骼序列的时间顺序及其组成片段的相似度来实现序列匹配。其中片段相似度由内容保持的低维编码表示决定,该编码采用变分自编码器(VAE)原理以无监督方式学习得到。我们通过检索和分类任务验证了所提表征方法的有效性:在主流骨骼序列数据集上,本方案不仅检索效果优于现有最优方法,更实现了最高达64倍的检索速度提升。|code|0| |DeCoDE: Detection of Cognitive Distortion and Emotion Cause Extraction in Clinical Conversations|Gopendra Vikram Singh, Soumitra Ghosh, Asif Ekbal, Pushpak Bhattacharyya|Indian Institute of Technology Bombay; Indian Institute of Technology Patna|Despite significant evidence linking mental health to almost every major development issue, individuals with mental disorders are among those most at risk of being excluded from development programs.

This work introduces a novel multi-modal mental health conversational corpus manually annotated with emotion , emotion causes , and the presence of cognitive distortion at the utterance level.

Complementary to these language models are probabilistic topic models that learn thematic patterns from the text. Recent work has demonstrated that conducting clustering on the word-level contextual representations from a language model emulates word clusters that are discovered in latent topics of words from Latent Dirichlet Allocation. The important question is how such topical word clusters are automatically formed, through clustering, in the language model when it has not been explicitly designed to model latent topics. To address this question, we design different probe experiments. Using BERT and DistilBERT, we find that the attention framework plays a key role in modelling such word topic clusters.

While effective, this can lead to local “hill climbing” rather than a more radical and innovative departure from standard methods. Moreover, if many participants build on similar baselines, the overall diversity of approaches considered may be limited. In this work, we propose a new class of IR evaluation metrics intended to promote greater diversity of approaches in evaluation campaigns. Whereas traditional IR metrics focus on user experience, our two “innovation” metrics instead reward exploration of more divergent, higher-risk strategies finding relevant documents missed by other systems. Experiments on four TREC collections show that our metrics do change system rankings by rewarding systems that find such rare, relevant documents. This result is further supported by a controlled, synthetic data experiment, and a qualitative analysis. In addition, we show that our metrics achieve higher evaluation stability and discriminative power than the standard metrics we modify.

However, a major issue with the user-item interaction graph in recommendation is the absence of the positional information of users/items, which limits the expressive power of graph recommenders in distinguishing the users/items with the same neighbours after propagating several graph convolution layers. Such a phenomenon further induces the well-known over-smoothing problem. We hypothesise that we can obtain a more expressive graph recommender through graph positional encoding (e.g., Laplacian eigenvector) thereby also alleviating the over-smoothing problem. Hence, we propose a novel model named Positional Graph Contrastive Learning (PGCL) for top-K recommendation, which aims to explicitly enhance graph representation learning with graph positional encoding in a contrastive learning manner. We show that concatenating the learned graph positional encoding and the pre-existing users/items' features in each feature propagation layer can achieve significant effectiveness gains. To further have sufficient representation learning from the graph positional encoding, we use contrastive learning to jointly learn the correlation between the pre-exiting users/items' features and the positional information. Our extensive experiments conducted on three benchmark datasets demonstrate the superiority of our proposed PGCL model over existing state-of-the-art graph-based recommendation approaches in terms of both effectiveness and alleviating the over-smoothing problem.|近年来,图神经网络已成为协同过滤领域的最先进技术,因为用户与项目之间的交互本质上具有图结构。然而,推荐系统中的用户-项目交互图存在一个关键缺陷:缺乏用户/项目的位置信息,这限制了图推荐模型在多层图卷积传播后区分具有相同邻居的用户/项目的能力。该现象进一步引发了众所周知的过平滑问题。我们假设通过图位置编码(如拉普拉斯特征向量)可以构建更具表达力的图推荐模型,从而缓解过平滑问题。为此,我们提出了一种名为"位置图对比学习"(PGCL)的新型Top-K推荐模型,其核心思想是通过对比学习方式显式增强图位置编码的表示学习能力。研究表明,在每个特征传播层将学习到的图位置编码与用户/项目的固有特征进行拼接,能显著提升模型效果。为了从图位置编码中获取更充分的表示学习,我们采用对比学习联合建模用户/项目固有特征与位置信息之间的关联。在三个基准数据集上的大量实验证明,相较于现有最先进的基于图的推荐方法,我们提出的PGCL模型在推荐效果和缓解过平滑问题方面均具有显著优势。|code|0| |Is Cross-Modal Information Retrieval Possible Without Training?|Hyunjin Choi, Hyunjae Lee, Seongho Joe, Youngjune Gwon|Samsung SDS|Encoded representations from a pretrained deep learning model (e.g., BERT text embeddings, penultimate CNN layer activations of an image) convey a rich set of features beneficial for information retrieval. Embeddings for a particular modality of data occupy a high-dimensional space of its own, but it can be semantically aligned to another by a simple mapping without training a deep neural net. In this paper, we take a simple mapping computed from the least squares and singular value decomposition (SVD) for a solution to the Procrustes problem to serve a means to cross-modal information retrieval. That is, given information in one modality such as text, the mapping helps us locate a semantically equivalent data item in another modality such as image. Using off-the-shelf pretrained deep learning models, we have experimented the aforementioned simple cross-modal mappings in tasks of text-to-image and image-to-text retrieval. Despite simplicity, our mappings perform reasonably well reaching the highest accuracy of 77% on recall@10, which is comparable to those requiring costly neural net training and fine-tuning. We have improved the simple mappings by contrastive learning on the pretrained models. Contrastive learning can be thought as properly biasing the pretrained encoders to enhance the cross-modal mapping quality. We have further improved the performance by multilayer perceptron with gating (gMLP), a simple neural architecture.|预训练深度学习模型生成的编码表示(如BERT文本嵌入、CNN倒数第二层图像激活特征)蕴含了丰富特征,对信息检索具有显著价值。特定模态数据的嵌入向量虽分布于各自高维空间,但通过简单映射即可实现跨模态语义对齐,而无需训练深度神经网络。本文采用最小二乘法与奇异值分解(SVD)求解Procrustes问题,构建跨模态信息检索的映射桥梁:当给定文本等单模态信息时,该映射可定位图像等目标模态中的语义等价项。基于现成的预训练模型,我们在文本-图像双向检索任务中验证了上述简单映射方案。尽管方法简洁,其表现却颇具竞争力——在recall@10指标上最高达到77%准确率,与需要昂贵神经网络训练调优的方案相当。我们进一步通过对比学习优化预训练模型,可视为对编码器施加恰当偏置以提升跨模态映射质量。此外,采用带门控的多层感知器(gMLP)这一简易神经架构,检索性能获得了进一步提升。

However, sequence-to-sequence models are known to be prone to “hallucinating” content that is not present in the source text. We argue that Doc2Query is indeed prone to hallucination, which ultimately harms retrieval effectiveness and inflates the index size. In this work, we explore techniques for filtering out these harmful queries prior to indexing. We find that using a relevance model to remove poor-quality queries can improve the retrieval effectiveness of Doc2Query by up to 16%, while simultaneously reducing mean query execution time by 30% and cutting the index size by 48%.

In this paper, we design a novel code summarization model CodeFiD to address this laborious challenge. Inspired by retrieval-augmented methods for open-domain question answering, CodeFiD first retrieves a set of relevant comments from code collections for a given code, and then aggregates presentations of code and these comments to produce a natural language sentence that summarizes the code behaviors. Different from current code summarization works that focus on improving code representations, our model resorts to external knowledge to enhance code summarizing performance. Extensive experiments on public code collections demonstrate the effectiveness of CodeFiD by outperforming state-of-the-art counterparts across all programming languages.|开源代码常面临注释缺失或描述不匹配的问题,导致代码理解困难,增加了软件开发和维护的负担。本文提出了一种新颖的代码摘要模型CodeFiD来解决这一难题。受开放域问答中检索增强方法的启发,CodeFiD首先从代码库中检索出与目标代码相关的一组注释,然后融合代码本身与这些注释的语义表示,最终生成描述代码行为的自然语言摘要。与当前主要聚焦于优化代码表征的摘要方法不同,本模型通过引入外部知识来提升代码摘要性能。在公开代码库上的大量实验表明,CodeFiD在所有编程语言中均超越现有最优模型,验证了其有效性。

Nevertheless, thosemodelsmay be brittle when faced to typos, distribution shifts or vulnerable to malicious attacks. For instance, several recent papers demonstrated that such variations severely impacted models performances, and then tried to train more resilient models. Usual approaches include synonyms replacements or typos injections - as data-augmentation - and the use of more robust tokenizers (characterBERT, BPE-dropout). To further complement the literature, we investigate in this paper adversarial training as another possible solution to this robustness issue. Our comparison includes the two main families of BERT-based neural retrievers, i.e. dense and sparse, with andwithout distillation techniques. We then demonstrate that one of the most simple adversarial training techniques - the Fast Gradient Sign Method (FGSM) - can improve first stage rankers robustness and effectiveness. In particular, FGSM increases models performances on both in-domain and out-of-domain distributions, and also on queries with typos, for multiple neural retrievers.|与基于术语的传统检索方法相比,神经检索模型近年来在效能上取得了显著提升。然而这类模型在面对拼写错误、分布偏移时可能表现脆弱,甚至容易受到恶意攻击。例如,多项最新研究表明此类数据变异会严重影响模型性能,随后学界开始尝试训练更具韧性的模型。常规方法包括采用同义词替换或拼写错误注入等数据增强策略,以及使用更鲁棒的标记器(如characterBERT、BPE-dropout)。为丰富现有研究体系,本文探索将对抗训练作为解决鲁棒性问题的另一种潜在方案。我们的对比实验涵盖基于BERT的两大类神经检索器——稠密检索与稀疏检索,并同时考虑是否采用知识蒸馏技术。研究结果表明,最简单的对抗训练技术之一——快速梯度符号法(FGSM)能够有效提升第一阶段排序器的鲁棒性与检索效能。具体而言,对于多种神经检索模型,FGSM在域内分布、域外分布以及含拼写错误的查询场景下均能提升模型性能。

However, most existing work focuses on a static setting or over a short-time window, leaving open questions about the long-term and dynamic impacts of news recommendations. In this paper, we explore these dynamic impacts through a systematic study of three research questions: 1) How do the news reading behaviors of users change after repeated long-term interactions with recommenders? 2) How do the inherent preferences of users change over time in such a dynamic recommender system? 3) Can the existing SOTA static method alleviate the problem in the dynamic environment? Concretely, we conduct a comprehensive data-driven study through simulation experiments of political polarization in news recommendations based on 40,000 annotated news articles. We find that users are rapidly exposed to more extreme content as the recommender evolves. We also find that a calibration-based intervention can slow down this polarization, but leaves open significant opportunities for future improvements|近期关于新闻推荐系统的研究表明,推荐算法可能导致用户过度接触强化其固有观点的内容。然而现有研究多聚焦于静态场景或短期观测窗口,对于新闻推荐产生的长期动态影响仍存在诸多未解之问。本文通过系统研究三个核心问题来探索这种动态影响:1) 用户在与推荐系统长期反复交互后,其新闻阅读行为如何演变?2) 在此类动态推荐系统中,用户固有偏好会随时间发生怎样的变化?3) 现有静态最优方法能否缓解动态环境下的问题?基于40,000篇标注新闻文章的政治极化模拟实验,我们开展了全面的数据驱动研究。研究发现随着推荐系统的演化,用户会快速接触到更极端的内容。同时发现基于校准的干预措施虽能延缓极化进程,但仍存在显著的改进空间以待未来探索。

Indeed, NLP performance highly depends upon the effectiveness of the preprocessing pipeline that builds the data representation. Many representation learning frameworks, such as Word2Vec, encode input data based on local contextual information that interconnects words. Such approaches can be computationally intensive, and their encoding is hard to explain. We here propose an interpretable representation learning framework utilizing Tsetlin Machine (TM). The TM is an interpretable logic-based algorithm that has exhibited competitive performance in numerous NLP tasks. We employ the TM clauses to build a sparse propositional (boolean) representation of natural language text. Each clause is a class-specific propositional rule that links words semantically and contextually. Through visualization, we illustrate how the resulting data representation provides semantically more distinct features, better separating the underlying classes. As a result, the following classification task becomes less demanding, benefiting simple machine learning classifiers such as Support Vector Machine (SVM). We evaluate our approach using six NLP classification tasks and twelve domain adaptation tasks. Our main finding is that the accuracy of our proposed technique significantly outperforms the vanilla TM, approaching the competitive accuracy of deep neural network (DNN) baselines. Furthermore, we present a case study showing how the representations derived from our framework are interpretable. (We use an asynchronous and parallel version of Tsetlin Machine: available at https://github.com/cair/PyTsetlinMachineCUDA ).|数据表示在自然语言处理(NLP)中扮演着关键角色,构成了大多数NLP任务的基础。事实上,NLP性能高度依赖于构建数据表示的预处理流程的有效性。许多表示学习框架(如Word2Vec)基于词语间相互关联的局部上下文信息对输入数据进行编码。这类方法通常计算密集,且其编码机制难以解释。本文提出了一种基于可解释性Tsetlin机(TM)的表示学习框架。TM是一种基于可解释逻辑的算法,已在多项NLP任务中展现出卓越性能。我们运用TM子句构建自然语言文本的稀疏命题(布尔)表示,每个子句都是连接语义与上下文信息的类别特定命题规则。通过可视化分析,我们展示了该方法生成的表示能提供语义区分度更高的特征,从而更好地区分潜在类别。这使得后续分类任务复杂度降低,有利于支持向量机(SVM)等简单分类器的性能提升。我们在六项NLP分类任务和十二项领域适应任务上评估了该方法,主要发现表明:所提技术的准确率显著优于基础TM,接近深度神经网络(DNN)基线模型的竞争力水平。此外,我们通过案例研究展示了该框架生成表示的强可解释性。(本研究采用异步并行版Tsetlin机实现,代码已开源:https://github.com/cair/PyTsetlinMachineCUDA)

Yet, a fair evaluation of new systems that retrieve documents outside the original judgment pool is not straightforward. Two common ways of dealing with unjudged documents are to remove them from a ranking (condensed lists), or to treat them as non- or highly relevant (naïve lower and upper bounds). However, condensed list-based measures often overestimate the effectiveness of a system, and naïve bounds are often very “loose”—especially for nDCG when some top-ranked documents are unjudged. As a new alternative, we employ bootstrapping to generate a distribution of nDCG scores by sampling judgments for the unjudged documents using run-based and/or pool-based priors. Our evaluation on four TREC collections with real and simulated cases of unjudged documents shows that bootstrapped nDCG scores yield more accurate predictions than condensed lists, and that they are able to strongly tighten upper bounds at a negligible loss of accuracy.|检索研究经常在TREC评测任务结束后复用其文档集。然而,当新系统检索到原始相关性判断池之外的文档时,如何进行公正评估并非易事。处理未判断文档的两种常见方法是:将其从排序结果中剔除(生成浓缩列表),或直接将其视为不相关/高度相关(朴素下限与上限)。但浓缩列表的评估指标往往会高估系统效果,而朴素边界通常过于"宽松"——特别是当排名靠前的文档未被判断时,对nDCG指标的影响尤为明显。我们提出一种基于自助法(bootstrapping)的新方案:通过运行结果或检索池的先验分布,为未判断文档采样生成相关性判断,进而构建nDCG得分的概率分布。在四个TREC文档集上的实验表明(包含真实和模拟的未判断文档场景),自助法生成的nDCG得分比浓缩列表更准确,且能在精度损失可忽略的前提下显著收紧评估上限。

It is challenging to identify the distinctive instances which are similar in semantics though holding different intentions. In this paper, we propose an intention-aware neural model for QPI. Question words (e.g., “when”) and blocks (e.g., “what time”) are extracted as features for revealing intentions. They are utilized to regulate pairwise question encoding explicitly and implicitly, within Conditional Variational AutoEncoder (CVAE) and multi-task VAE frameworks, respectively. We conduct experiments on the benchmark corpora QQP, LCQMC and BQ, towards both English and Chinese QPI tasks. Experimental results show that our method yields generally significant improvements compared to a variety of PLM-based baselines (BERT, RoBERTa and ERNIE), and it outperforms the state-of-the-art QPI models. It is also proven that our method doesn’t severely reduce the overall efficiency, which merely extends the training time by 12.5% on a RTX3090. All the models and source codes will be made publicly available to support reproducible research.|我们针对问题复述识别(Question Paraphrasing Identification, QPI)任务展开研究,该任务旨在判断一对疑问句(即问题)是否互为复述,在信息检索和问答系统中具有广泛应用。当语义相似但意图不同的特殊实例出现时,准确识别面临重大挑战。本文提出一种面向QPI的意图感知神经网络模型。通过提取疑问词(如"when")和疑问块(如"what time")作为揭示意图的特征,分别在条件变分自编码器(CVAE)框架和多任务VAE框架中实现显式和隐式的成对问题编码调控。我们在QQP、LCQMC和BQ基准语料库上开展了中英文QPI任务的对比实验,结果表明:相比基于预训练语言模型(BERT、RoBERTa和ERNIE)的各类基线方法,我们的方法普遍取得显著提升,并优于当前最先进的QPI模型。实验同时证实该方法不会严重降低整体效率,在RTX3090显卡上仅使训练时间延长12.5%。所有模型与源代码将公开以支持可复现研究。|code|0| |Document-Level Relation Extraction with Distance-Dependent Bias Network and Neighbors Enhanced Loss|Hao Liang, Qifeng Zhou|Xiamen Univ, Dept Automat, Xiamen 361005, Peoples R China|Document-level relation extraction (DocRE), in contrast to sentence-level, requires additional context to be considered. Recent studies, when extracting contextual information about entities, treat information about the whole document equally, which inevitably suffers from irrelevant information. This has been demonstrated to make the model not robust: it predicts correctly when an entire document is fed but errs when non-evidence sentences are removed. In this work, we propose three novel components to improve the robustness of the model by selectively considering the context of the entities. Firstly, we propose a new method for computing the distance between tokens that reduces the distance between evidence sentences and entities. Secondly, we add a distance-dependent bias network to each self-attention building block to exploit the distance information between tokens. Finally, we design an auxiliary loss for entities with higher attention to close tokens in the attention mechanism. Experimental results on three DocRE benchmark datasets show that our model not only outperforms existing models but also has strong robustness.|与句子级关系抽取不同,文档级关系抽取(DocRE)需要考虑更广泛的上下文信息。近期研究在提取实体上下文信息时,对整篇文档信息采取均等处理方式,这不可避免地会引入无关信息干扰。研究表明这种做法会导致模型鲁棒性不足:当输入完整文档时预测正确,但移除非证据句子后就会出现错误。针对这一问题,我们提出三个创新组件来通过选择性关注实体上下文提升模型鲁棒性。首先,我们提出新的词元距离计算方法,通过缩短证据句子与实体之间的距离来优化上下文选择。其次,我们在每个自注意力模块中融入距离依赖偏置网络,以有效利用词元间的距离信息。最后,我们设计辅助损失函数,促使注意力机制中实体对邻近词元给予更高关注。在三个DocRE基准数据集上的实验结果表明,我们的模型不仅性能优于现有模型,还具有更强的鲁棒性。

Ruggero|Sease Ltd, London, England|Interleaving is an online evaluation approach for information retrieval systems that compares the effectiveness of ranking functions in interpreting the users' implicit feedback. Previous work such as Hofmann et al. (2011) [11] has evaluated the most promising interleaved methods at the time, on uniform distributions of queries. In the real world, usually, there is an unbalanced distribution of repeated queries that follows a long-tailed users' search demand curve. This paper first aims to reproduce the Team Draft Interleaving accuracy evaluation on uniform query distributions [11] and then focuses on assessing how this method generalises to long-tailed real-world scenarios. The replicability work raised interesting considerations on how the winning ranking function for each query should impact the overall winner for the entire evaluation. Based on what was observed, we propose that not all the queries should contribute to the final decision in equal proportion. As a result of these insights, we designed two variations of the Delta(AB) score winner estimator that assign to each query a credit based on statistical hypothesis testing. To reproduce, replicate and extend the original work, we have developed from scratch a system that simulates a search engine and users' interactions from datasets from the industry. Our experiments confirm our intuition and show that our methods are promising in terms of accuracy, sensitivity, and robustness to noise.|交错排列法(Interleaving)是一种用于信息检索系统的在线评估方法,它通过解读用户的隐式反馈来比较不同排序函数的效果。先前的研究(如Hofmann等人2011年发表的论文[11])曾在均匀分布的查询条件下评估了当时最具潜力的交错排列方法。但在现实场景中,重复查询往往呈现非均衡分布,遵循用户搜索需求的长尾曲线。本文首先旨在复现团队草拟交错法(Team Draft Interleaving)在均匀查询分布下的准确度评估[11],继而重点研究该方法如何推广至长尾分布的现实场景。在复现过程中,我们发现每个查询的优胜排序函数对整体评估结果的影响机制值得深入探讨。基于观察结果,我们认为并非所有查询都应以同等权重参与最终决策。基于这些发现,我们设计了两种改进版Delta(AB)分数胜出评估器,通过统计假设检验为每个查询分配权重值。为完整复现、验证并拓展原始研究,我们自主开发了模拟搜索引擎的系统,并使用工业级数据集模拟用户交互行为。实验结果表明,我们的改进方法在准确度、敏感度和抗噪性方面均展现出显著优势,验证了理论设想的有效性。

Improvements to both sparse and dense models have also been noted, in the context of open-domain question answering. However, the increasing sophistication of proposed techniques places a growing strain on the reproducibility of results. Our work aims to tackle this challenge. In Generation Augmented Retrieval (GAR), a sequence-to-sequence model was used to generate candidate answer strings as well as titles of documents and actual sentences where the answer string might appear; this query expansion was applied before traditional sparse retrieval. Distilling Knowledge from Reader to Retriever (DKRR) used signals from downstream tasks to train a more effective Dense Passage Retrieval (DPR) model. In this work, we first replicate the results of GAR using a different codebase and leveraging a more powerful sequence-to-sequence model, T5. We provide tight integration with Pyserini, a popular IR toolkit, where we also add support for the DKRR-based DPR model: the combination demonstrates state-of-the-art effectiveness for retrieval in open-domain QA. To account for progress in generative readers that leverage evidence fusion for QA, so-called fusion-in-decoder (FiD), we incorporate these models into our PyGaggle toolkit. The result is a reproducible, easy-to-use, and powerful end-to-end question-answering system that forms a starting point for future work. Finally, we provide evaluation tools that better gauge whether models are generalizing or simply memorizing.|在信息检索领域,稠密-稀疏混合模型因其卓越效能而日益受到青睐。特别是在开放域问答场景中,稀疏模型与稠密模型的性能提升已有显著成果。然而,随着技术方案的日趋复杂,研究成果的可复现性正面临严峻挑战。本项研究致力于解决这一关键问题。

在生成增强检索(GAR)方法中,研究者采用序列到序列模型同时生成候选答案字符串、可能包含答案的文档标题及实际句子;这种查询扩展技术被应用于传统稀疏检索之前。而"从阅读器到检索器的知识蒸馏"(DKRR)则通过下游任务信号来训练更高效的稠密段落检索(DPR)模型。本研究首先基于不同代码库复现了GAR的实验结果,并采用性能更强的T5序列到序列模型。我们实现了与主流信息检索工具包Pyserini的深度集成,同时新增了对DKRR-DPR模型的支持:实验表明该组合在开放域问答检索任务中达到了最先进的效能水平。

为适应生成式阅读器的最新进展(如利用证据融合进行问答的解码器融合技术FiD),我们将这些模型整合至PyGaggle工具包。最终构建出一个具备可复现性、易用性强且性能优异的端到端问答系统,为后续研究提供了基准框架。特别值得指出的是,我们还开发了新型评估工具,可更精准地判别模型是真正实现了泛化能力还是仅进行数据记忆。|code|0| |Pre-processing Matters! Improved Wikipedia Corpora for Open-Domain Question Answering|Manveer Singh Tamber, Ronak Pradeep, Jimmy Lin|Univ Waterloo, David R Cheriton Sch Comp Sci, Waterloo, ON, Canada|One of the contributions of the landmark Dense Passage Retriever (DPR) work is the curation of a corpus of passages generated from Wikipedia articles that have been segmented into non-overlapping passages of 100 words. This corpus has served as the standard source for question answering systems based on a retriever–reader pipeline and provides the basis for nearly all state-of-the-art results on popular open-domain question answering datasets. There are, however, multiple potential drawbacks to this corpus. First, the passages do not include tables, infoboxes, and lists. Second, the choice to split articles into non-overlapping passages results in fragmented sentences and disjoint passages that models might find hard to reason over. In this work, we experimented with multiple corpus variants from the same Wikipedia source, differing in passage size, overlapping passages, and the inclusion of linearized semi-structured data. The main contribution of our work is the replication of Dense Passage Retriever and Fusion-in-Decoder training on our corpus variants, allowing us to validate many of the findings in previous work and giving us new insights into the importance of corpus pre-processing for open-domain question answering. With better data preparation, we see improvements of over one point on both the Natural Questions dataset and the TriviaQA dataset in end-to-end effectiveness over previous work measured using the exact match score. Our results demonstrate the importance of careful corpus curation and provide the basis for future work.|具有里程碑意义的《密集段落检索器(DPR)》研究的重要贡献之一,是构建了一个基于维基百科文章的段落语料库——这些文章被分割为每段100词且互不重叠的文本单元。该语料库已成为基于检索-阅读器架构的问答系统标准数据源,并为当前主流开放域问答数据集上几乎所有最先进成果提供了基准。然而,该语料库存在若干潜在缺陷:首先,其段落未包含表格、信息框及列表等半结构化数据;其次,采用非重叠式文章分割策略会导致句子碎片化,产生语义割裂的段落,可能影响模型的推理能力。本研究针对同一维基百科源数据,实验了多种语料变体方案,包括调整段落长度、采用重叠段落策略以及引入线性化半结构化数据。我们的核心贡献在于:基于这些语料变体复现了密集段落检索器与解码器融合训练过程,既验证了前人研究的诸多结论,又揭示了语料预处理对开放域问答的重要影响。通过优化数据预处理方法,我们在Natural Questions和TriviaQA数据集上实现了端到端性能提升——以精确匹配分数衡量,较前人工作均超过1个百分点的进步。这些结果不仅证明了精细语料构建的关键价值,更为后续研究奠定了基础。

Investigating data as networks requires pre-processing, retrieval or filtering, conversion of data into networks, and application of various network analysis approaches. These processes are usually complex and hard to perform without some programming knowledge and resources. To the best of our knowledge, most solutions attempting to make these functionalities accessible to users focus on particular processes in isolation without exploring how these processes could be further abstracted or combined in a real-world application to assist users in their data exploration and knowledge extraction journey. Furthermore, most applications focusing on such approaches tend to be closed-source. This paper introduces a solution that combines the approaches above as part of Collaboration Spotting X (CSX), an open-source network-based visual analytics tool for retrieving, modeling, and exploring or analyzing data as networks. It abstracts the concepts above through the use of multiple interactive visualizations. In addition to being an easily accessible open-source platform for data exploration and analysis, CSX can also serve as a real-world evaluation platform for researchers in related computer science areas who wish to test their solutions and approaches to machine learning, visualizations, interactions, and more in a real-world system.|将数据以网络形式表示和可视化是一种广泛应用于医学、社会科学和信息检索等高度关联数据领域的分析方法。将数据作为网络进行研究需要经过预处理、检索或过滤、数据网络化转换以及应用各类网络分析技术等步骤。这些流程通常较为复杂,若不具备编程知识和资源则难以实施。据我们所知,当前大多数旨在降低使用门槛的解决方案都只聚焦于特定环节的独立功能,未能探索如何在实际应用中进一步抽象或整合这些流程,从而协助用户完成数据探索与知识挖掘的全过程。此外,专注于此类方法的应用程序多数为闭源系统。本文提出的解决方案将上述方法整合到协作发现平台X(CSX)中——这是一个基于网络的开源可视化分析工具,支持数据的检索、建模、探索及网络化分析。该平台通过多重交互式可视化实现了对上述概念的抽象化处理。除作为便捷开源的数据探索分析平台外,CSX还可作为现实场景的评估平台,供相关计算机科学领域的研究者测试机器学习、可视化技术、交互设计等解决方案在真实系统中的应用效果。|code|0| |TweetStream2Story: Narrative Extraction from Tweets in Real Time|Mafalda Castro, Alípio Jorge, Ricardo Campos|INESC TEC|The rise of social media has brought a great transformation to the way news are discovered and shared.

However, its large volume of tweets also makes it impossible for a user to keep up with an event. In this work, we present TweetStream2Story, a web app for extracting narratives from tweets posted in real time, about a topic of choice.

Distribution of visual attention is studied in a controlled experiment, wherein eye-tracking data and web logs are collected for 18 participants exploring newsfeeds in a single- and multi-column layout. Behavior is modeled using Weibull analysis of item (article) visit times, which describes these visits via quantities like durations and frequencies of switching focused item.

However, the generated data can be of subpar quality and struggle to maintain the same characteristics as the original dataset. To this end, we propose a Data Augmentation method for low-resource and imbalanced datasets, by aligning Language Models to in-domain data prior to generating synthetic examples. In particular, we propose the alignment of existing generic models in task-specific unlabeled data, in order to create better synthetic examples and boost performance in Text Classification tasks. We evaluate our approach on three diverse and well-known Language Models, four datasets, and two settings (i.e. imbalance and low-resource) in which Data Augmentation is usually deployed, and study the correlation between the amount of data required for alignment, model size, and its effects in downstream in-domain and out-of-domain tasks.

Multi-armed bandit, which has been widely applied to various online systems, is quite capable of delivering such efficient recommendation services. To further enhance online recommendations, many works have introduced clustering techniques to fully utilize users’ information. These works consider symmetric relations between users, i.e., users in one cluster share equal weights. However, in practice, users usually have different interaction frequency (i.e., activeness) in one cluster, and their collaborative relations are unsymmetrical. This brings a challenge for bandit clustering since inactive users lack the capability of leveraging these interaction information to mitigate the cold-start problem, and further affect active ones belonging to one cluster.

Recent approaches to topic modeling use pretrained contextualized language models and variational autoencoders. However, large neural topic models have a considerable memory footprint. In this paper, we propose a knowledge distillation framework to compress a contextualized topic model without loss in topic quality. In particular, the proposed distillation objective is to minimize the cross-entropy of the soft labels produced by the teacher and the student models, as well as to minimize the squared 2-Wasserstein distance between the latent distributions learned by the two models. Experiments on two publicly available datasets show that the student trained with knowledge distillation achieves topic coherence much higher than that of the original student model, and even surpasses the teacher while containing far fewer parameters than the teacher. The distilled model also outperforms several other competitive topic models on topic coherence.|主题建模是探索网络及数字图书馆文档集合的主流方法。当前的主题建模技术采用预训练的上下文感知语言模型与变分自编码器。然而,大型神经主题模型存在显著的内存占用问题。本文提出一种知识蒸馏框架,可在保证主题质量无损的前提下压缩上下文主题模型。具体而言,该蒸馏目标旨在最小化师生模型生成软标签的交叉熵,同时最小化两模型所学潜在分布之间的2-Wasserstein平方距离。在两个公开数据集上的实验表明:通过知识蒸馏训练的学生模型,其主题连贯性显著优于原始学生模型,甚至在参数量远少于教师模型的情况下实现反超。经蒸馏的模型在主题连贯性指标上也优于其他多个竞争性主题模型。

We propose to construct heterogeneous social context graphs around news articles and reformulate the problem as a graph classification task.

In this context, the classification of a word is based on the similarity of its representation to the prototypes built for each event type and for the “non-event” class (also named null class). However, the “non-event” prototype aggregates by definition a set of semantically heterogeneous words, which hurts the discrimination between trigger and non-trigger words. We address this issue by handling the detection of non-trigger words as an out-of-domain (OOD) detection problem and propose a method for dynamically setting a similarity threshold to perform this detection.

We specifically combined multiple annotated datasets from previous studies, corresponding to either emotional lexica or short text documents, and evaluated models of multiple sizes and trained under different settings.

The ubiquitous use of social media platforms lays out the perfect avenue for exploring mental health manifestations in posts and interactions with other users. Current methods for depression detection from social media mainly focus on text processing, and only a few also utilize images posted by users. In this work, we propose a flexible time-enriched multimodal transformer architecture for detecting depression from social media posts, using pretrained models for extracting image and text embeddings. Our model operates directly at the user-level, and we enrich it with the relative time between posts by using time2vec positional embeddings. Moreover, we propose another model variant, which can operate on randomly sampled and unordered sets of posts to be more robust to dataset noise.

Recent studies dedicate to catching the relationships within the triplet of passage, question, and option. Nevertheless, one limitation in current approaches relates to the fact that confusing distractors are often mistakenly judged as correct, due to the fact that models do not emphasize the differences between the answer alternatives. Motivated by the way humans deal with multi-choice questions by comparing given options, we propose CoLISA (Contrastive Learning and In-Sample Attention), a novel model to prudently exclude the confusing distractors. In particular, CoLISA acquires option-aware representations via contrastive learning on multiple options. Besides, in-sample attention mechanisms are applied across multiple options so that they can interact with each other. The experimental results on QuALITY and RACE demonstrate that our proposed CoLISA pays more attention to the relation between correct and distractive options, and recognizes the discrepancy between them. Meanwhile, CoLISA also reaches the state-of-the-art performance on QuALITY (Our code is available at https://github.com/Walle1493/CoLISA. .).|多选阅读理解任务(MC-RC)要求通过阅读并理解给定篇章和问题,从多个候选选项中选出最恰当的答案。近期研究致力于捕捉篇章、问题与选项三者间的关联关系。然而,现有方法存在一个显著局限:由于模型未能充分强调备选答案之间的差异,常将干扰性错误选项误判为正确答案。受人类通过对比给定选项来处理多选题的思维模式启发,我们提出CoLISA模型(对比学习与样本内注意力机制),旨在审慎排除混淆性干扰项。具体而言,CoLISA通过多选项的对比学习获取选项感知表征,并采用跨选项的样本内注意力机制实现选项间交互。在QuALITY和RACE数据集上的实验表明,我们提出的CoLISA能更聚焦于正确答案与干扰项之间的关系,有效识别二者差异。同时,CoLISA在QuALITY数据集上达到了当前最先进的性能水平(代码已开源:https://github.com/Walle1493/CoLISA)。

Bridge|Univ Coll Cork, Sch Comp Sci & IT, Insight Ctr Data Analyt, Cork, Ireland|Playlists are a major way of interacting with music, as evidenced by the fact that streaming services currently host billions of playlists. In this content overload scenario, it is crucial to automatically characterise playlists, so that music can be effectively organised, accessed and retrieved. One way to characterise playlists is by their listening context. For example, one listening context is “workout”, which characterises playlists suited to be listened to by users while working out. Recent work attempts to predict the listening contexts of playlists, formulating the problem as multi-label classification. However, current classifiers for listening context prediction are limited in the input data modalities that they handle, and on how they leverage the inputs for classification. As a result, they achieve only modest performance. In this work, we propose to use knowledge graphs to handle multi-modal inputs, and to effectively leverage such inputs for classification. We formulate four novel classifiers which yield approximately 10% higher performance than the state-of-the-art. Our work is a step forward in predicting the listening contexts of playlists, which could power important real-world applications, such as context-aware music recommender systems and playlist retrieval systems.|播放列表是用户与音乐互动的主要方式,流媒体服务平台上现存数十亿播放列表便是明证。在这种内容过载的场景下,自动识别播放列表特征对于有效组织、访问和检索音乐至关重要。其中一种特征识别方式是通过收听场景进行分类,例如"健身"场景就对应适合用户在运动时收听的播放列表。近期研究尝试将播放列表场景预测构建为多标签分类问题,但现有分类器在输入数据处理模态和特征利用方式上存在局限,导致预测性能仅达到中等水平。本研究提出采用知识图谱来处理多模态输入数据并高效利用这些数据进行分类,构建了四种新型分类器,其性能较现有最优技术提升约10%。本成果推动了播放列表场景预测领域的发展,可为上下文感知音乐推荐系统和播放列表检索系统等重要实际应用提供技术支持。

Moreno, Antoine Doucet|University of La Rochelle, L3i|In this paper, we address the detection of named entities in multilingual historical collections. We argue that, besides the multiple challenges that depend on the quality of digitization (e.g., misspellings and linguistic errors), historical documents can pose another challenge due to the fact that such collections are distributed over a long enough period of time to be affected by changes and evolution of natural language. Thus, we consider that detecting entities in historical collections is time-sensitive, and explore the inclusion of temporality in the named entity recognition (NER) task by exploiting temporal knowledge graphs. More precisely, we retrieve semantically-relevant additional contexts by exploring the time information provided by historical data collections and include them as mean-pooled representations in a Transformer-based NER model. We experiment with two recent multilingual historical collections in English, French, and German, consisting of historical newspapers (19C-20C) and classical commentaries (19C).

Then we propose an effective method for learning information from an external knowledge base that gives hints on temporal commonsense knowledge. Using prepared dataset, we introduce a new machine learning model that incorporates the information from the knowledge base and demonstrate that our model outperforms state-of-the-art approaches in the proposed task.|在故事理解、信息检索、微博用户状态追踪及聊天机器人对话等应用中,判断文本信息是否持续有效具有重要意义。这种能力不仅有助于深入理解叙事内容,但计算机执行此类推断仍存在困难,因其需要时间常识的支撑。受传统自然语言推理启发,我们提出"时序自然语言推理"这一新任务,旨在判定文本内容的时效有效性。该任务要求根据补充内容,推断并判断句子描述的动作是持续进行还是已经完成,进而确定该句子是否仍然有效。我们首先构建了专用数据集并训练多个机器学习模型,随后提出一种从外部知识库中学习时序常识线索的有效方法。基于该数据集,我们引入融合知识库信息的新型机器学习模型,实验证明该模型在当前任务中优于最先进的基线方法。

Kato|Univ Tsukuba, Tsukuba, Ibaraki, Japan; Gunosy Inc, Shibuya, Japan|This study presents a theoretical analysis on the efficiency of interleaving, an efficient online evaluation method for rankings. Although interleaving has already been applied to production systems, the source of its high efficiency has not been clarified in the literature. Therefore, this study presents a theoretical analysis on the efficiency of interleaving methods. We begin by designing a simple interleaving method similar to ordinary interleaving methods. Then, we explore a condition under which the interleaving method is more efficient than A/B testing and find that this is the case when users leave the ranking depending on the item's relevance, a typical assumption made in click models. Finally, we perform experiments based on numerical analysis and user simulation, demonstrating that the theoretical results are consistent with the empirical results.|本研究针对交错排名(interleaving)这一高效的在线排序评估方法进行了理论效率分析。尽管交错法已应用于生产系统,但其高效性的来源在现有文献中尚未得到明确阐释。为此,本研究系统分析了交错法的效率机制:首先设计了一种与常规交错法类似的简化方法;随后通过理论推导发现,当用户基于条目相关性决定是否退出排名(点击模型中普遍采用的典型假设)时,该方法的评估效率显著优于传统的A/B测试;最后通过数值分析和用户模拟实验验证了理论结论与实证结果的一致性。|code|0| |An Experimental Study on Pretraining Transformers from Scratch for IR|Carlos Lassance, Hervé Déjean, Stéphane Clinchant|Naver Labs Europe|Finetuning Pretrained Language Models (PLM) for IR has been de facto the standard practice since their breakthrough effectiveness few years ago. But, is this approach well understood? In this paper, we study the impact of the pretraining collection on the final IR effectiveness. In particular, we challenge the current hypothesis that PLM shall be trained on a large enough generic collection and we show that pretraining from scratch on the collection of interest is surprisingly competitive with the current approach. We benchmark first-stage ranking rankers and cross-encoders for reranking on the task of general passage retrieval on MSMARCO, Mr-Tydi for Arabic, Japanese and Russian, and TripClick for specific domain. Contrary to popular belief, we show that, for finetuning first-stage rankers, models pretrained solely on their collection have equivalent or better effectiveness compared to more general models. However, there is a slight effectiveness drop for rerankers pretrained only on the target collection. Overall, our study sheds a new light on the role of the pretraining collection and should make our community ponder on building specialized models by pretraining from scratch. Last but not least, doing so could enable better control of efficiency, data bias and replicability, which are key research questions for the IR community.|微调预训练语言模型(PLM)用于信息检索(IR)自几年前其突破性效果显现以来,已成为实际上的标准实践。但这种方法是否被充分理解?本文研究了预训练数据集对最终IR效果的影响。我们特别挑战了当前"PLM应在足够大的通用语料库上训练"的假设,并证明直接在目标数据集上从头预训练的模型竟能与现有方法媲美。我们在MSMARCO通用段落检索任务、阿拉伯语/日语/俄语的Mr-Tydi数据集以及特定领域的TripClick数据集上,对第一阶段排序模型和重排序交叉编码器进行了基准测试。与普遍认知相反,研究表明:对于第一阶段排序模型的微调,仅用目标数据集预训练的模型效果与通用模型相当或更优;但仅用目标数据预训练的重排序模型会出现轻微效果下降。总体而言,本研究为预训练数据集的作用提供了新视角,促使学界重新思考通过从头预训练构建专用模型的价值。更重要的是,这种方法能更好地控制模型效率、数据偏差和可复现性——这些正是IR领域的核心研究议题。|code|0| |Multimodal Inverse Cloze Task for Knowledge-Based Visual Question Answering|Paul Lerner, Olivier Ferret, Camille Guinaudeau|Université Paris-Saclay, CEA, List; Université Paris-Saclay, CNRS, LISN|We present a new pre-training method, Multimodal Inverse Cloze Task, for Knowledge-based Visual Question Answering about named Entities (KVQAE).

Towards Aspect Based Sentiment Intensity Analysis|Mamta, Asif Ekbal|IIT Patna|Aspect-based sentiment analysis (ABSA) is a fast-growing research area in natural language processing (NLP) that provides more fine-grained information, considering the aspect as the fundamental item. The ABSA primarily measures sentiment towards a given aspect, but does not quantify the intensity of that sentiment. For example, intensity of positive sentiment expressed for service in service is good is comparatively weaker than in service is excellent. Thus, aspect sentiment intensity will assist the stakeholders in mining user preferences more precisely. Our current work introduces a novel task called aspect based sentiment intensity analysis (ABSIA) that facilitates research in this direction. An annotated review corpus for ABSIA is introduced by labelling the benchmark SemEval ABSA restaurant dataset with the seven (7) classes in a semi-supervised way. To demonstrate the effective usage of corpus, we cast ABSIA as a natural language generation task, where a natural sentence is generated to represent the output in order to utilize the pre-trained language models effectively. Further, we propose an effective technique for the joint learning where ABSA is used as a secondary task to assist the primary task, i.e. ABSIA. An improvement of 2 points is observed over the single task intensity model. To explain the actual decision process of the proposed framework, model explainability technique is employed that extracts the important opinion terms responsible for generation (Source code and the dataset has been made available on https://www.iitp.ac.in/~ai-nlp-ml/resources.html#ABSIA , https://github.com/20118/ABSIA )|基于方面的情感分析(ABSA)作为自然语言处理(NLP)领域快速发展的研究方向,以方面项为基本单元提供细粒度情感信息。传统ABSA主要检测给定方面的情感倾向,但未量化情感强度。例如"服务不错"中表达的正面情感强度明显弱于"服务极佳"。因此,方面情感强度分析将帮助利益相关方更精准地挖掘用户偏好。本研究创新性地提出了"基于方面的情感强度分析(ABSIA)"任务以推动该方向研究,通过半监督方式在SemEval ABSA餐厅评论基准数据集上标注七级强度标签构建首个ABSIA标注语料库。为验证语料库的有效性,我们将ABSIA重构为自然语言生成任务,通过生成自然语句作为输出来充分利用预训练语言模型。进一步提出联合学习框架,以ABSA作为辅助任务提升主要任务ABSIA的性能,实验表明该框架相较单一任务强度模型提升2个性能点。采用模型可解释性技术揭示了框架生成决策的关键意见词。(源代码与数据集已公开于:https://www.iitp.ac.in/~ai-nlp-ml/resources.html#ABSIAhttps://github.com/20118/ABSIA)

In this work, we propose a novel unsupervised approach, called HINT, which identifies coherent Hierarchical Information Threads. These threads can enable users to easily interpret a hierarchical association of diverse evolving information about an event or discussion. In particular, HINT deploys a scalable architecture based on network community detection to effectively identify hierarchical links between documents based on their chronological relatedness and answers to the 5W1H questions (i.e., who, what, where, when, why & how). On the NewSHead collection, we show that HINT markedly outperforms existing state-of-the-art approaches in terms of the quality of the identified threads. We also conducted a user study that shows that our proposed network-based hierarchical threads are significantly ( $$p &lt; 0.05$$ ) preferred by users compared to cluster-based sequential threads.|随着每日在线信息量(如新闻文章)的急剧增长,亟需自动化方法来追踪事件动态演变过程中相关联的信息(即信息脉络)。本研究提出一种名为HINT的新型无监督方法,用于识别具有层次结构的连贯信息脉络(Hierarchical Information Threads)。这些脉络能帮助用户直观理解事件或讨论中多样化演进信息的层级关联。具体而言,HINT采用基于网络社区检测的可扩展架构,通过分析文档的时间关联性及其对5W1H要素(何人、何事、何地、何时、为何及如何)的回应,有效识别文档间的层次化关联。在NewSHead数据集上的实验表明,HINT在信息脉络识别质量上显著优于现有最优方法。通过用户调研进一步证实,与基于聚类的线性脉络相比,本方法提出的网络化层次脉络获得用户显著偏好($$p < 0.05$$)。

Cao et al. [8] proposed a data- and compute-efficient method for cross-lingual adjustment of mBERT that uses a small parallel corpus to make embeddings of related words across languages similar to each other. They showed it to be effective in NLI for five European languages. In contrast we experiment with a topologically diverse set of languages (Spanish, Russian, Vietnamese, and Hindi) and extend their original implementations to new tasks (XSR, NER, and QA) and an additional training regime (continual learning). Our study reproduced gains in NLI for four languages, showed improved NER, XSR, and cross-lingual QA results in three languages (though some cross-lingual QA gains were not statistically significant), while mono-lingual QA performance never improved and sometimes degraded. Analysis of distances between contextualized embeddings of related and unrelated words (across languages) showed that fine-tuning leads to “forgetting” some of the cross-lingual alignment information. Based on this observation, we further improved NLI performance using continual learning.

This has become even more important, as the average reader is not as willing to spare more time out of their already busy schedule as in the past, thus prioritizing news in a summarized format, which are faster to digest. On top of that, people tend to increasingly rely on strong visual components to help them understand the focal point of news articles in a less tiresome manner. This growing demand, focused on exploring information through visual aspects, urges the need for the emergence of alternative approaches concerned with text understanding and narrative exploration. This motivated us to propose Text2Storyline, a platform for generating and exploring enriched storylines from an input text, a URL or a user query. The latter is to be issued on the Portuguese Web Archive (Arquivo.pt), therefore giving users the chance to expand their knowledge and build up on information collected from web sources of the past.

In addition, the system is equipped with an explainable user interface through which fact-checkers and content managers can visualise in detail the features leading to a certain prediction and have the possibility for manual cross-checking.|社交媒体在日常生活中的广泛应用及其所导致的不实信息在这些平台上的传播,极大地助长了虚假新闻现象演变为全球性问题。目前已有多种人工与自动化手段试图应对这一近乎失控的挑战。本文提出Facade虚假新闻检测系统,旨在提供一套完整的新闻文章分类解决方案,并解释每项预测背后的决策依据。该系统采用级联架构设计,包含分别处理低维与高维特征描述符的两条分类流水线,其核心目标是确保每个判定结果都能获得一致的置信度评分。此外,系统配备了可解释性用户界面,事实核查员与内容管理者可通过该界面可视化追溯影响特定预测的关键特征,并支持人工交叉验证功能。|code|0| |PsyProf: A Platform for Assisted Screening of Depression in Social Media|Anxo Pérez, Paloma PiotPerezAbadin, Javier Parapar, Álvaro Barreiro|Univ A Coruna, Informat Retrieval Lab, CITIC, Campus Elvina S-N, La Coruna 15071, Spain|Depression is one of the most prevalent mental disorders. For its effective treatment, patients need a quick and accurate diagnosis. Mental health professionals use self-report questionnaires to serve that purpose. These standardized questionnaires consider different depression symptoms in their evaluations. However, mental health stigmas heavily influence patients when filling out a questionnaire. In contrast, many people feel more at ease discussing their mental health issues on social media. This demo paper presents a platform for assisted examination and tracking of symptoms of depression for social media users. In order to bring a broader context, we have complemented our tool with user profiling. We show a platform that helps professionals with data labelling, relying on depression estimators and profiling models.|抑郁症是最普遍的精神障碍之一。要实现有效治疗,患者需要快速准确的诊断。心理健康专业人员通常使用自评问卷进行评估。这些标准化问卷在评估中会考量不同的抑郁症状。然而在填写问卷时,患者极易受到心理健康污名化的影响。相比之下,许多人在社交媒体上讨论心理健康问题时更为放松。本文展示了一个面向社交媒体用户的抑郁症状辅助检测与追踪平台。为了构建更全面的评估语境,我们通过用户画像功能对工具进行了补充。该平台依托抑郁评估模型和用户画像模型,能够辅助专业人员完成数据标注工作。

The significant potential for the application of AI to Law, for instance, by creating computational solutions for legal tasks, has intrigued researchers for decades. This appeal has only been amplified with the advent of Deep Learning (DL). It is worth noting that working with legal text is far more challenging as compared to the other subdomains of IR/NLP, mainly due to the typical characteristics of legal text, such as considerably longer documents, complex language and lack of large-scale annotated datasets. In this tutorial, we introduce the audience to these characteristics of legal text, and with it, the challenges associated with processing the legal documents. We touch upon the history of AI and Law research, and how it has evolved over the years from relatively simpler approaches to more complex ones, such as those involving DL. We organize the tutorial as follows. First, we provide a brief introduction to state-of-the-art research in the general domain of IR and NLP. We then discuss in more detail IR/NLP tasks specific to the legal domain. We outline the methodologies (both from an academic and industry perspective), and the available tools and datasets to evaluate the methodologies.

This is especially important for safety-critical tasks. One shared characteristic of these critical tasks is their risk sensitivity, where small mistakes can cause big consequences and even endanger life. There are several factors that could be guidelines for the successful deployment of AI systems in sensitive tasks: (i) failure detection and out-of-distribution (OOD) detection; (ii) overfitting identification; (iii) uncertainty quantification for predictions; (iv) robustness to data perturbations. These factors are also challenges of current AI systems, which are major blocks for building safe and reliable AI. Specifically, the current AI algorithms are unable to identify common causes for failure detection. Furthermore, additional techniques are required to quantify the quality of predictions. All these contribute to inaccurate uncertainty quantification, which lowers trust in predictions. Hence obtaining accurate model uncertainty quantification and its further improvement are challenging. To address these issues, many techniques have been proposed, such as regularization methods and learning strategies. As vision and language are the most typical data type and have many open source benchmark datasets, this thesis will focus on vision-language data processing for tasks like classification, image captioning, and vision question answering. In this thesis, we aim to build a safeguard by further developing current techniques to ensure the accurate model uncertainty for safety-critical tasks.|尽管人工智能系统已应用于多个领域并展现出卓越性能,但其安全性与可靠性仍备受关注。对于安全关键型任务而言,这一问题尤为重要。这类任务共有的核心特征是其风险敏感性——细微的差错可能引发严重后果,甚至危及生命。成功部署AI系统至敏感任务需重点考量以下要素:(i)故障检测与分布外(OOD)检测;(ii)过拟合识别;(iii)预测不确定性量化;(iv)数据扰动鲁棒性。这些要素既是当前AI系统面临的挑战,也是构建安全可靠AI的主要障碍。具体而言,现有AI算法无法识别故障检测的常见诱因,且需额外技术手段评估预测质量,这些缺陷共同导致不确定性量化失准,最终削弱预测结果的可信度。因此,如何实现精确的模型不确定性量化并持续优化仍具挑战性。

针对上述问题,研究者已提出正则化方法、学习策略等多种解决方案。鉴于视觉与语言数据是最典型的数据类型且拥有大量开源基准数据集,本论文将聚焦视觉-语言数据处理任务,如图像分类、图像描述生成和视觉问答。本研究旨在通过深度开发现存技术,构建面向安全关键型任务的防护机制,从而确保模型不确定性的精确量化。

With the usage of transfer learning, an extensive data analysis and classification of the presented domains will be conducted. The classification models will be enhanced during and after training using a knowledge graph, containing additional information (i.e. named entities, relationships, topics), to find explicit insights about the common traits or lines of disinformative arguments in an article.

Existing research focuses on extreme forms of conflict, largely ignoring the lesser forms which still pose a significant threat to consumer and brand welfare. This research aims to capture the full spectrum of online conflict, providing a comprehensive overview of the problem from an interdisciplinary marketing and computer science perspective. I propose a further investigation into online hate, utilising big data analysis to establish an understanding of triggers, consequences and brand responses to online hate. Initially, I will conduct a systematic literature review exploring the definitions and methodology used within the hate research domain. Secondly, I will conduct an investigation into state-of-the-art models and classification systems, producing an analysis on the prevalence of hate and its various forms on social media. Finally, I plan to establish the features of social media data which constitute triggers for online conflicts. Then, through a combination of user studies, sentiment analysis, and emotion detection I will examine the consequences of these conflicts.

The lab consists of three tasks, two of which are continuation of EXIST 2022 (sexism detection and sexism categorization) and a third and novel one on source intention identification. For this edition new test and training data will be provided and some novelties are introduced in order to tackle two central problems of Natural Language Processing (NLP): bias and fairness. Firstly, the sampling and data gathering process will take into account different sources of bias in data: seed, temporal and user bias. During the annotation process we will also consider some sources of "label bias" that come from the social and demographic characteristics of the annotators. Secondly, we will adopt the "learning with disagreements" paradigm by providing datasets containing also pre-aggregated annotations, so that systems can make use of this information to learn from different perspectives. The general goal of the EXIST shared tasks is to advance the state of the art in online sexism detection and categorization, as well as investigating to what extent bias can be characterized in data and whether systems may take fairness decisions when learning from multiple annotations.|本文介绍了将在CLEF 2023会议上举办的"社交媒体性别歧视识别实验室"(EXIST 2023)。该实验室包含三项任务,其中两项延续了EXIST 2022的研究内容(性别歧视检测与分类),第三项则是新增的"来源意图识别"任务。本届活动将提供新的测试和训练数据,并引入创新方法以应对自然语言处理(NLP)中的两个核心问题:偏见与公平性。首先,在样本选取和数据收集过程中将考量数据偏差的不同来源:种子偏差、时间偏差和用户偏差。在标注过程中,我们还将考虑标注者社会人口特征带来的"标签偏差"。其次,我们将采用"从分歧中学习"的研究范式,提供包含预聚合标注的数据集,使系统能够利用这些信息从多视角进行学习。EXIST共享任务的总体目标是推动在线性别歧视检测与分类的技术前沿,同时探究数据中偏见特征的量化方法,以及系统在从多重标注学习时能否做出公平性决策。|code|0| |Extractive Summarization of Financial Earnings Call Transcripts - Or: When GREP Beat BERT|Timothy Nugent, George Gkotsis, Jochen L.

Customer feedback serves as an independent validation tool that could boost consumer trust in the brand. Whether it is a recommendation or review of a product, it provides insight allowing businesses to understand what they are doing right or wrong. By automatically analyzing customer complaints at the aspect-level enterprises can connect to their customers by customizing products and services according to their needs quickly and deftly. In this paper, we introduce the task of Aspect-Based Complaint Detection (ABCD). ABCD identifies the aspects in the given review about a product and also finds if the aspect mentioned in the review signifies a complaint or non-complaint. Specifically, a task solver must detect duplets (What, How) from the inputs that show WHAT the targeted features are and HOW they are complaints. To address this challenge, we propose a deep-learning-based multi-modal framework, where the first stage predicts what the targeted aspects are, and the second stage categorizes whether the targeted aspect is associated with a complaint or not. We annotate the aspect categories and associated complaint/non-complaint labels in the recently released multi-modal complaint dataset (CESAMARD), which spans five domains (books, electronics, edibles, fashion, and miscellaneous). Based on extensive evaluation our methodology established a benchmark performance in this novel aspect-based complaint detection task and also surpasses a few strong baselines developed from state-of-the-art related methods (Resources available at: https://github.com/appy1608/ECIR2023_Complaint-Detection ).|随着技术进步,电子商务网站和社交媒体平台的普及为消费者提供了基于整体体验向企业反馈的渠道。客户反馈作为一种独立验证工具,能够增强消费者对品牌的信任。无论是对产品的推荐还是评价,这些反馈都能为企业提供洞察,使其了解自身经营的优势与不足。通过基于方面的客户投诉自动分析,企业可以快速精准地根据客户需求定制产品与服务,从而建立深度客户连接。本文提出了基于方面的投诉检测任务(ABCD),其核心是从产品评论中识别具体方面,并判定该方面内容是否构成投诉。具体而言,任务求解器需要从输入中检测二元组(What,How),即明确"针对什么特征"以及"该特征如何构成投诉"。为应对这一挑战,我们提出基于深度学习的多模态框架:第一阶段预测目标方面,第二阶段分类该方面是否关联投诉。我们在最新发布的多模态投诉数据集(CESAMARD)上标注了方面类别及对应的投诉/非投诉标签,该数据集涵盖图书、电子产品、食品、服装和综合类五大领域。经广泛评估,我们的方法在这一创新型基于方面的投诉检测任务中确立了基准性能,并超越了基于当前最先进相关方法构建的若干强基线模型。(资源详见:https://github.com/appy1608/ECIR2023_Complaint-Detection)

Towards Interpretable Complaint Cause Analysis|Apoorva Singh, Prince Jha, Rohan Bhatia, Sriparna Saha|Indian Inst Technol Patna, Bihta, India|The abundance of information available on social media and the regularity with which complaints are posted online emphasizes the need for automated complaint analysis tools. Prior study has focused chiefly on complaint identification and complaint severity prediction: the former attempts to classify a piece of content as either complaint or non-complaint. The latter seeks to group complaints into various severity classes depending on the threat level that the complainant is prepared to accept. The complainant’s goal could be to express disapproval, seek compensation, or both. As a result, the complaint detection model should be interpretable or explainable. Recognizing the cause of a complaint in the text is a crucial yet untapped area of natural language processing research. We propose an interpretable complaint cause analysis model that is grounded on a dyadic attention mechanism. The model jointly learns complaint classification, emotion recognition, and polarity classification as the first sub-problem. Subsequently, the complaint cause extraction and the associated severity level prediction as the second sub-problem. We add the causal span annotation for the existing complaint classes in a publicly available complaint dataset to accomplish this. The results indicate that existing computational tools can be repurposed to tackle highly relevant novel tasks, thereby finding new research opportunities (Resources available at: https://bit.ly/Complaintcauseanalysis ).|社交媒体上充斥着海量信息,用户频繁在线发布投诉内容的现象凸显了自动化投诉分析工具的必要性。现有研究主要聚焦于投诉识别与投诉严重程度预测两大方向:前者旨在将内容分类为投诉或非投诉,后者则根据投诉者可接受的威胁等级将投诉划分至不同严重级别。投诉者的意图可能包括表达不满、寻求赔偿或二者兼具,因此投诉检测模型需具备可解释性。识别文本中的投诉成因是自然语言处理研究中一个关键但尚未开发的领域。本研究提出了一种基于双元注意力机制的可解释投诉成因分析模型,该模型通过两阶段任务进行联合学习:首先将投诉分类、情感识别和极性分类作为第一子任务,随后将投诉成因提取及关联的严重程度预测作为第二子任务。为实现这一目标,我们在公开可用的投诉数据集上对现有投诉类别补充了因果跨度标注。实验结果表明,现有计算工具可被重新部署以解决高度相关的新任务,从而开辟新的研究机遇(资源获取地址:https://bit.ly/Complaintcauseanalysis)。

Research on ID becomes important when authors’ written online communication pertains to sensitive domains, e.g., mental health. Over time, researchers have utilized AI-based automated word spinners (e.g., SpinRewriter, WordAI) for paraphrasing content. However, these tools fail to satisfy the purpose of ID as their paraphrased content still leads to the source when queried on search engines. There is limited prior work on judging the effectiveness of paraphrasing methods for ID on search engines or their proxies, neural retriever ( NeurIR ) models. We propose a framework where, for a given sentence from an author’s post, we perform iterative perturbation on the sentence in the direction of paraphrasing with an attempt to confuse the search mechanism of a NeurIR system when the sentence is queried on it. Our experiments involve the subreddit “r/AmItheAsshole” as the source of public content and Dense Passage Retriever as a NeurIR system-based proxy for search engines. Our work introduces a novel method of phrase-importance rankings using perplexity scores and involves multi-level phrase substitutions via beam search. Our multi-phrase substitution scheme succeeds in disguising sentences 82% of the time and hence takes an essential step towards enabling researchers to disguise sensitive content effectively before making it public.

NER in French and other relatively limited-resource languages cannot always benefit from approaches proposed for languages like English due to a dearth of large, robust datasets. In this paper, we present our work that aims to mitigate the effects of this dearth of large, labeled datasets. We propose a Transformer-based NER approach for French, using adversarial adaptation to similar domain or general corpora to improve feature extraction and enable better generalization. Our approach allows learning better features using large-scale unlabeled corpora from the same domain or mixed domains to introduce more variations during training and reduce overfitting. Experimental results on three labeled datasets show that our adaptation framework outperforms the corresponding non-adaptive models for various combinations of Transformer models, source datasets, and target corpora. We also show that adversarial adaptation to large-scale unlabeled corpora can help mitigate the performance dip incurred on using Transformer models pre-trained on smaller corpora.|命名实体识别(NER)是指在文本中识别预定义类别的命名实体并对其进行分类的任务。由于缺乏大规模高质量数据集,法语等资源相对受限的语言无法直接受益于为英语等语言设计的现有方法。本文提出了一种基于Transformer的法语NER解决方案,通过对抗式适应技术利用相似领域或通用语料库来优化特征提取能力并提升模型泛化性能。该方法能够借助来自同领域或混合领域的大规模无标注语料库学习更优特征表示,通过在训练过程中引入更多数据变化来降低过拟合风险。在三个标注数据集上的实验结果表明:针对不同Transformer模型、源数据集和目标语料库的组合,我们的适应框架均显著优于非自适应模型。研究还证实,通过对抗式适应大规模无标注语料库,可以有效缓解因使用小规模语料预训练的Transformer模型而导致的性能下降问题。|code|0| |Justifying Multi-label Text Classifications for Healthcare Applications|João Figueira, Gonçalo M. Correia, Michalina Strzyz, Afonso Mendes|Priberam Labs, Lisbon, Portugal|The healthcare domain is a very active area of research for Natural Language Processing (NLP). The classification of medical records according to codes from the International Classification of Diseases (ICD) is an essential task in healthcare. As a very sensitive application, the automatic classification of personal medical records cannot be immediately trusted without human approval. As such, it is desirable for classification models to provide reasons for each decision, such that the medical coder can validate model predictions without reading the entire document. AttentionXML is a multi-label classification model that has shown high applicability for this task and can provide attention distributions for each predicted label. In practice, we have found that these distributions do not always provide relevant spans of text. We propose a simple yet effective modification to AttentionXML for finding spans of text that can better aid the medical coders: splitting the BiLSTM of AttentionXML into a forward and a backward LSTM, creating two attention distributions that find the leftmost and rightmost limits of the text spans. We also propose a novel metric for the usefulness of our model’s suggestions by computing the drop in confidence from masking out the selected text spans. We show that our model has a similar classification performance to AttentionXML while surpassing it in obtaining relevant text spans.|医疗领域是自然语言处理(NLP)研究的重要方向。根据国际疾病分类(ICD)编码对医疗记录进行分类是医疗保健中的关键任务。作为高度敏感的应用场景,个人医疗记录的自动分类必须经人工审核后才能采信。因此,理想的分类模型应能提供每个决策的判断依据,使医疗编码员无需通读全文即可验证模型预测结果。AttentionXML作为一种多标签分类模型,已在该任务中展现出卓越性能,并能为每个预测标签生成注意力分布。但在实际应用中,我们发现这些注意力分布并不总能定位到相关文本片段。为此,我们对AttentionXML提出了简单而有效的改进:将其双向LSTM(BiLSTM)拆分为前向和后向LSTM,通过生成两个注意力分布分别定位文本片段的左右边界。我们还提出了一种新颖的评估指标,通过计算遮蔽选定文本片段后模型置信度的下降幅度,量化模型建议的实用价值。实验表明,改进后的模型在保持与AttentionXML相当分类性能的同时,能更精准地定位相关文本片段。|code|0| |Towards Quantifying the Privacy of Redacted Text|Vaibhav Gusain, Douglas J.

We have also investigated the abstractive and compressive summarization approaches for our comparative analysis. The code of the proposed work is available at the github repository https://github.com/vishalsinghroha/Unsupervised-Comment-based-Multi-document-Extractive-Summarization .|【工作摘要】本研究提出了一种无监督的抽取式摘要生成框架,该框架通过整合终端用户发布的评论来生成高质量摘要。基于进化多目标优化思想,我们同步优化了多个评估摘要质量的客观函数,包括句子多样性以及与评论内容的相关性。现有研究表明命名实体识别(NER)技术在摘要生成中具有重要作用,而本工作首次创新性地引入了一个新型目标函数——该函数通过结合新闻文档与用户评论中的NER信息来对新闻语句进行评分。为验证新目标函数的有效性,我们在英语和法语数据集上采用ROUGE-1、ROUGE-2和ROUGE-SU4 F1值作为评估指标,测试了基于NER的目标函数与现有目标函数的不同组合效果。此外,我们还对比分析了生成式摘要与压缩式摘要方法。本研究的代码已开源至GitHub仓库:https://github.com/vishalsinghroha/Unsupervised-Comment-based-Multi-document-Extractive-Summarization|[code](https://paperswithcode.com/search?q_meta=&q_type=&q=MOO-CMDS+NER:+Named+Entity+Recognition-Based+Extractive+Comment-Oriented+Multi-document+Summarization)|0| |Evaluating Humorous Response Generation to Playful Shopping Requests|Natalie Shapira, Oren Kalinsky, Alex Libov, Chen Shani, Sofia Tolmach|Hebrew Univ Jerusalem, Jerusalem, Israel; Bar Ilan Univ, Ramat Gan, Israel; Amazon Sci, Tel Aviv, Israel|AI assistants are gradually becoming embedded in our lives, utilized for everyday tasks like shopping or music. In addition to the everyday utilization of AI assistants, many users engage them with playful shopping requests, gauging their ability to understand - or simply seeking amusement. However, these requests are often not being responded to in the same playful manner, causing dissatisfaction and even trust issues. In this work, we focus on equipping AI assistants with the ability to respond in a playful manner to irrational shopping requests. We first evaluate several neural generation models, which lead to unsuitable results - showing that this task is non-trivial. We devise a simple, yet effective, solution, that utilizes a knowledge graph to generate template-based responses grounded with commonsense. While the commonsense-aware solution is slightly less diverse than the generative models, it provides better responses to playful requests. This emphasizes the gap in commonsense exhibited by neural language models.|人工智能助手正逐渐融入我们的日常生活,被用于购物、音乐等日常事务。除了常规使用外,许多用户会向AI助手提出带有游戏性质的购物请求,既是为了测试其理解能力,有时也单纯为了娱乐消遣。然而这些请求往往得不到同样趣味性的回应,导致用户不满甚至产生信任危机。本研究致力于赋予AI助手以游戏化方式应对非理性购物请求的能力。我们首先评估了若干神经生成模型,但其输出结果不尽如人意——表明该任务具有相当挑战性。为此,我们设计了一种简单而有效的解决方案:利用知识图谱生成基于模板且符合常识的回应。虽然这种常识感知方案在多样性上略逊于生成模型,但对游戏化请求的回应质量更优。这一发现凸显了神经语言模型在常识理解方面存在的显著差距。

Santosh, Philipp Bock, Matthias Grabmair|Technical University of Munich|Segmentation and Rhetorical Role Labeling of legal judgements play a crucial role in retrieval and adjacent tasks, including case summarization, semantic search, argument mining etc. Previous approaches have formulated this task either as independent classification or sequence labeling of sentences. In this work, we reformulate the task at span level as identifying spans of multiple consecutive sentences that share the same rhetorical role label to be assigned via classification. We employ semi-Markov Conditional Random Fields (CRF) to jointly learn span segmentation and span label assignment. We further explore three data augmentation strategies to mitigate the data scarcity in the specialized domain of law where individual documents tend to be very long and annotation cost is high. Our experiments demonstrate improvement of span-level prediction metrics with a semi-Markov CRF model over a CRF baseline. This benefit is contingent on the presence of multi sentence spans in the document.|法律判决书的分段与修辞角色标注在检索及相关任务(包括案例摘要、语义搜索、论点挖掘等)中发挥着关键作用。先前的研究方法将该任务视为句子的独立分类或序列标注问题。在本工作中,我们将任务重新定义为在文本片段层面识别共享相同修辞角色标签的连续多句片段,并通过分类进行标注。我们采用半马尔可夫条件随机场(CRF)联合学习片段分割与片段标签分配,并进一步探索三种数据增强策略以缓解法律专业领域的数据稀缺问题——该领域的文件通常篇幅冗长且标注成本高昂。实验结果表明,相较于基础CRF模型,半马尔可夫CRF模型在片段级预测指标上有所提升,但这一优势取决于文档中是否存在多句片段的情况。

There has been growing evidence of social media abuse towards influencing politics and social issues in other countries, raising numerous concerns. The identification and prevention of coordinated campaigns has become critical to tackling disinformation at its source. Existing approaches to detect malicious campaigns make strict assumptions about coordinated behaviours, such as malicious accounts perform synchronized actions or share features assumed to be indicative of coordination. Others require part of the malicious accounts in the campaign to be revealed in order to detect the rest. Such assumptions significantly limit the effectiveness of existing approaches. In contrast, we propose AMDN (Attentive Mixture Density Network) to automatically uncover coordinated group behaviours from account activities and interactions between accounts, based on temporal point processes. Furthermore, we leverage the learned model to understand and explain the behaviours of coordinated accounts in disinformation campaigns. We find that the average influence between coordinated accounts is the highest, whereas these accounts are not much influenced by regular accounts. We evaluate the effectiveness of the proposed method on Twitter data related to Russian interference in US Elections. Additionally, we identify disinformation campaigns in COVID-19 data collected from Twitter, and provide the first evidence and analysis of existence of coordinated disinformation campaigns in the ongoing pandemic.|社交媒体上的虚假信息宣传活动日益猖獗,这些活动通过恶意账户的协同操作来操纵公众舆论。越来越多证据表明,社交媒体正被滥用于影响他国政治和社会议题,引发了广泛担忧。识别和阻断协同式虚假宣传,已成为从源头遏制虚假信息传播的关键。现有恶意活动检测方法对协同行为做出了严格假设,例如要求恶意账户执行同步动作或共享某些预设的协同特征指标;部分方法甚至需要先暴露部分恶意账户才能检测其余成员。这些假设严重制约了现有方法的有效性。为此,我们提出AMDN(注意力混合密度网络)模型,基于时序点过程理论,从账户活动轨迹及其互动关系中自动识别群体协同行为。通过该学习模型,我们进一步解析并阐释了虚假宣传中协同账户的行为模式,发现协同账户间具有最高平均影响力,而普通账户对其影响甚微。我们在涉及俄罗斯干预美国大选的推特数据集上验证了该方法,同时在新冠疫情相关推文数据中首次发现并系统分析了协同式虚假宣传活动存在的实证依据。|code|0|
