From Graphs to Hypergraphs: Enhancing Aspect-Term Sentiment Analysis via Multi-Level Relational Modeling (2026.acl-srw)
Copied to clipboard
| Challenge: | Existing graph-based approaches to predict sentiment polarity for specific aspect terms rely on predefined pairwise structures to improve expressive capacity. |
| Approach: | They propose a dynamic hypergraph framework that can be used to generate a single instance-specific hypergraph from contextual token representations. |
| Outcome: | The proposed framework improves on Lap14, Rest14, and MAMS . it uses a single instance-specific hypergraph constructed directly from contextual token representations . |
