Papers with Event Semantic Relation Reasoning
Event-Centric Question Answering via Contrastive Learning and Invertible Event Transformation (2022.findings-emnlp)
Copied to clipboard
| Challenge: | Existing QA frameworks that use event-centric reasoning are lacking. |
| Approach: | They propose a novel QA model with contrastive learning and invertible event transformation . they use an invertable transformation matrix to project event vectors into a common event embedding space . |
| Outcome: | The proposed model achieves 8.4% gain in token-level F1 score and 3.0% gain in Exact Match score on the ESTER dataset. |
ESTER: A Machine Reading Comprehension Dataset for Reasoning about Event Semantic Relations (2021.emnlp-main)
Copied to clipboard
| Challenge: | Recent event-centric reading comprehension datasets focus mostly on event arguments or temporal relations. |
| Approach: | They propose a machine reading comprehension dataset that leverages natural language queries to reason about the five most common event semantic relations. |
| Outcome: | The proposed dataset shows that current SOTA systems achieve 22.1%, 63.3% and 83.5% for token-based exact-match, **F1** and event-based **HIT@1** scores. |
