Table-based Fact Verification with Self-labeled Keypoint Alignment (2022.coling-1)
Copied to clipboard
| Challenge: | Existing methods for fact verification rely on graph feature or data augmentation but fail to investigate evidence correlation between statement and table effectively. |
| Approach: | They propose a self-labeled keypoint alignment model to explore correlation between statement and table . they propose integrating a mixture-of experts block to integrate interacted information . |
| Outcome: | The proposed model outperforms the state-of-the-art models and captures interpretable evidence words on three widely-studied datasets. |
