MURRE: Multi-Hop Table Retrieval with Removal for Open-Domain Text-to-SQL (2025.coling-main)
Copied to clipboard
| Challenge: | Existing multi-hop retrieval of open-domain text-to-SQL tasks is not applicable due to the tendency to retrieve tables similar to those already retrieved but irrelevant to the question. |
| Approach: | They propose a multi-hop table retrieval with removal task to retrieve unretrieved tables from open-domain text-to-SQL databases. |
| Outcome: | The proposed method improves performance 5.7% over the previous state-of-the-art methods on open-domain text-to-SQL datasets. |
