Legal Judgment Prediction via Event Extraction with Constraints

1 code implementation ACL 2022 Yi Feng, Chuanyi Li, Vincent Ng

While significant progress has been made on the task of Legal Judgment Prediction (LJP) in recent years, the incorrect predictions made by SOTA LJP models can be attributed in part to their failure to (1) locate the key event information that determines the judgment, and (2) exploit the cross-task consistency constraints that exist among the subtasks of LJP.
