CORE-T: COherent REtrieval of Tables for Text-to-SQL
CORE-T introduces a training-free framework for improving table retrieval in text-to-SQL systems by combining dense retrieval with LLM-generated metadata and compatibility caching. The approach achieves significant performance gains—up to 22.7 points in table-selection F1 and 24.4 points in multi-table execution accuracy—while reducing inference tokens by 64-76% compared to LLM-intensive alternatives.
