Researchers have developed a novel multi-agent framework designed to improve the accuracy and reliability of Natural Language to SQL (NL2SQL) queries. This system addresses common LLM limitations like hallucinating schema elements and generating invalid queries by incorporating domain relevance detection, schema-grounded knowledge construction, and KPI-aware SQL synthesis. It further enhances precision through syntax-level self-repair using SQLite execution feedback and semantic consistency checks via SQL-to-NL reverse engineering. Tested on a dataset of 60 queries, the framework achieved 90% correctness using Mistral, demonstrating its potential for high-stakes environments such as insurance. AI
IMPACT Enhances the reliability of LLMs for complex data querying, potentially enabling broader adoption in regulated industries.
