bert-finetuned-bpmn

This model is a fine-tuned version of bert-base-cased on a dataset containing textual process descriptions.

The dataset contains 2 target labels:

• AGENT
• TASK

The dataset (and the notebook used for training) can be found on the following GitHub repo: https://github.com/jtlicardo/bert-finetuned-bpmn

Update: a model trained on 5 BPMN-specific labels can be found here: https://huggingface.co./jtlicardo/bpmn-information-extraction

The model achieves the following results on the evaluation set:

• Loss: 0.2656
• Precision: 0.7314
• Recall: 0.8366
• F1: 0.7805
• Accuracy: 0.8939
