Researchers have developed CLARITY, a new framework and benchmark designed to evaluate Natural Language to SQL (NL2SQL) systems' ability to handle ambiguous and unanswerable queries in interactive settings. Unlike previous benchmarks, CLARITY generates complex ambiguities and simulates diverse user interactions across multiple turns. Evaluations on existing datasets like Spider and BIRD revealed that current leading NL2SQL systems, even those powered by large language models, experience significant performance drops when faced with these multifaceted ambiguities, often failing to pinpoint the exact source of the issue.
