This paper presents AgentNLQ, a multi-agent system for natural language to SQL conversion that achieves 78.1% semantic accuracy on the BIRD benchmark through schema enrichment and a self-correcting orchestrator.
FD-NL2SQL is a feedback-driven natural language to SQL system for clinical oncology databases that improves with use through clinician edits and logic-based SQL augmentation. The system decomposes natural language questions into predicates, retrieves expert-verified exemplars, and synthesizes executable SQL with continuous learning capabilities.
ROSE is a novel intent-centered evaluation metric for NL2SQL that uses a Prover-Refuter cascade to assess semantic correctness independently of ground-truth SQL, achieving 24% better agreement with human experts than existing metrics. The paper addresses limitations of Execution Accuracy and provides a re-evaluation of 19 NL2SQL methods with publicly released resources.
