Conundrums in Event Coreference Resolution: Making Sense of the State of the Art

Constrained Multi-Task Learning for Bridging Resolution

1 code implementation ACL 2022 Hideo Kobayashi, Yufang Hou, Vincent Ng

We examine the extent to which supervised bridging resolvers can be improved without employing additional labeled bridging data by proposing a novel constrained multi-task learning framework for bridging resolution, within which we (1) design cross-task consistency constraints to guide the learning process; (2) pre-train the entity coreference model in the multi-task framework on the large amount of publicly available coreference data; and (3) integrating prior knowledge encoded in rule-based resolvers.

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.

End-to-End Neural Bridging Resolution

no code implementations COLING 2022 Hideo Kobayashi, Yufang Hou, Vincent Ng

The state of bridging resolution research is rather unsatisfactory: not only are state-of-the-art resolvers evaluated in unrealistic settings, but the neural models underlying these resolvers are weaker than those used for entity coreference resolution.
