Components of CASIE are written in Python:

1. nug_arg_detection.py (applied Domain-Word2vec) or nug_arg_detection_bert.py (applied BERT) are for training the neural classifier to detect nugget and argument.
2. realis_identify.py is for training the neural classifier to identify realis for event nugget.
3. role_phrase.py is for training the neural classifier to assign roles to arguments.
4. link_coref.py is for identifying realis and linking role using in the trained models and grouping the mentions of the coreference events.
5. Others scripts are needed for running CASIE's components.

The corpus contains 1000 annotation and source files. Our cybersecurity focused on five event types: Databreach, Phishing, Ransom, Discover, and Patch.

More details of the annotation and CASIE's system are in the papers. If you use our data, please cite one of the following papers.
