Dataset

The dataset is in support of our approach to utilize LLMs to translate natural language into an intermediate representation with Python syntax that facilitates final conversion into widely adopted business process definition languages.

The approach and the methodology that was used to create and validate the dataset can be found in the arxiv paper

The dataset consists of 101 incremental build test cases targeted at supporting and evaluating approaches and research in natural language-driven business process automation.

To ensure compact and clear representations of prior context and expected workflows, FLOW-BENCH adopts a constrained subset of Python syntax. This subset includes assignment statements, conditional statements (if-statements), loops (for and while), and function calls.

The conditional_ootb.yaml file contains the 101 tests. An example test is shown below:

  - _metadata:
      tags:
        - "97"
        - conditional_update
        - conditional_update_replace
      uid: 97
    input:
      utterance: |-
        Instead of retrieving all the issues just create a new issue in each repo
      prior_sequence:
        - |-
          repositories = GitHub_Repository__3_0_0__retrievewithwhere_Repository()
          for repo in repositories:
            new_issue = GitHub_Issue__3_0_0__retrievewithwhere_Issue()
      prior_context: []
      bpmn:
        $ref: "context/uid_97_context.bpmn"
    expected_output:
      sequence:
        - |-
          repositories = GitHub_Repository__3_0_0__retrievewithwhere_Repository()
          for repo in repositories:
            updated_issue = GitHub_Issue__3_0_0__create_Issue()
      bpmn:
        $ref: "output/uid_97_output.bpmn"

The example contains metadata along with tags that outline whether the test is conditional, or linear as well as if its update, delete or implicitly creation. The prior_sequence contains pythonic syntax representation of the previously created BPMN. bpmn points to the corresponding BPMN representations available in the context folder. The expected_output contains the groud truth pythonic syntax representation as well as a reference to the bpmn representation which can be found in the output folder.

The ootb_catalog.json file contains the unique identified id as well as the description of the API. An example is shown below

{
    "id": "bambooHR_benefits__2_0_0__retrievewithwhere_benefits",
    "description": "Retrieve all the benefit deduction types"
}

Approach

For details on the approach to generate flows and the evaluation results on the tests suite refer to Sections 3 and 4 of the arxiv paper, respectively.
