Advancing Event Causality Identification via Heuristic Semantic Dependency Inquiry Network

1 code implementation20 Sep 2024 Haoran Li, Qiang Gao, Hongmei Wu, Li Huang

However, these approaches fall short in two dimensions: (1) causal features between events in a text often lack explicit clues, and (2) external knowledge may introduce bias, while specific problems require tailored analyses.
