Bidirectional Semantic Enhancement for Schema Routing Across Large-Scale Databases (2026.findings-acl)
Copied to clipboard
| Challenge: | Existing methods relying on unidirectional query expansion fail to bridge lexical mismatches and graph-based approaches struggle to navigate schemas when explicit structural links are missing. |
| Approach: | They propose a retrieval framework that bridges the semantic gap between user queries and vague schema definitions by performing online generative query expansion. |
| Outcome: | The proposed retrieval framework bridges the semantic gap between user queries and vague schema definitions by enriching table schemas offline and performing online generative query expansion. |
