RelU-Net: Syntax-aware Graph U-Net for Relational Triple Extraction (2022.emnlp-main)
Copied to clipboard
| Challenge: | Existing methods focused on capturing semantic information but failed to incorporate syntactic structures of the sentence, which is proved to contain rich relational information. |
| Approach: | They propose a framework to capture syntactic information for relational triple extraction by contracting dependency tree into a core relational topology and eliminating redundant information with graph pooling operations. |
| Outcome: | The proposed framework incorporates syntactic information for relational triple extraction. |
