AttnLink framework converts LLM attention to schema links for Text-to-SQL

Researchers have introduced AttnLink, a novel framework designed to enhance Text-to-SQL systems by converting a language model's internal attention mechanisms into relevance scores for schema items. This approach allows for efficient ranking of schema candidates in a single pass, reducing inference latency. Two variants, AttnLink-U and AttnLink-S, were developed, with AttnLink-S incorporating direct supervision to align attention distributions with gold schema items. Experiments on benchmark datasets like Spider, BIRD, and Spider2-SQLite demonstrated AttnLink-S's high performance in schema linking and its effectiveness in improving downstream SQL generation accuracy.
