LEVEN: A Large-Scale Chinese Legal Event Detection Dataset

Understand

Recognizing facts is the most fundamental step in making judgments, hence detecting events in the legal documents is important to legal case analysis tasks.

• However, existing Legal Event Detection (LED) datasets only concern incomprehensive event types and have limited annotated data, which restricts the development of LED methods and their downstream applications.
• To alleviate these issues, we present LEVEN a large-scale Chinese LEgal eVENt detection dataset, with 8,116 legal documents and 150,977 human-annotated event mentions in 108 event types.
• Not only charge-related events, LEVEN also covers general events, which are critical for legal case understanding but neglected in existing LED datasets.
