Enhancing Document-level Event Argument Extraction with Contextual Clues and Role Relevance (2023.findings-acl)
Copied to clipboard
| Challenge: | Document-level event argument extraction is a challenging task for cross-sentence inference . previous work focused on document-level EAE, but recent work focused more on documentlevel . |
| Approach: | They propose a document-level event argument extraction model that captures contextual clues and latent role information. |
| Outcome: | The proposed model outperforms existing methods on two public datasets with 1.13 F1 and 2.64 F1 improvements on RAMS and WikiEvents respectively. |
A Compressive Memory-based Retrieval Approach for Event Argument Extraction (2025.coling-main)
Copied to clipboard
| Challenge: | Existing retrieval-based EAE methods have input length constraints and the gap between the retriever and the inference model. |
| Approach: | They propose a retrieval-based retrieval mechanism that overcomes input length constraints . they use compressive memory to cache retrieved information and support continuous updates . |
| Outcome: | The proposed method outperforms retrieval-based methods on three public datasets. |
