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. |
USSA: A Unified Table Filling Scheme for Structured Sentiment Analysis (2023.acl-long)
Copied to clipboard
| Challenge: | Structured Sentiment Analysis (SSA) is a problem of bi-lexical dependency parsing . previous studies have cast it as a bottleneck because of overlap and discontinuity issues . |
| Approach: | They propose a bi-lexical dependency parsing graph and a table-filling scheme that addresses overlap and discontinuity issues. |
| Outcome: | The proposed framework outperforms state-of-the-art methods on benchmark datasets. |
