Q2EI: Query-to-Entity Inference for Semantic Condensation in Domain-Specific Retrieval (2026.findings-acl)
Copied to clipboard
| Challenge: | Existing generative expansions introduce redundancy or hallucinations that cause semantic drift. |
| Approach: | They propose a query rewriting strategy that reframes rewrite as semantic condensation rather than expansion. |
| Outcome: | The proposed method outperforms baselines on medical and legal benchmarks while reducing token consumption. |
