Revisiting Structured Sentiment Analysis as Latent Dependency Graph Parsing (2024.acl-long)
Copied to clipboard
| Challenge: | Structured Sentiment Analysis (SSA) is a problem of bi-lexical dependency graph parsing due to the internal structures of spans neglected. |
| Approach: | They propose to use latent spans as latent subtrees to model internal structures of spans and leverage TreeCRFs to extract the complete opinion tuple from a sentence. |
| Outcome: | The proposed method performs significantly better than all previous bi-lexical methods, achieving new state-of-the-art. |
