Over six months, Hassanzadeh enhanced the Text2SQL evaluation framework in the IBM/unitxt repository, focusing on metrics accuracy, reliability, and maintainability. He introduced new execution and non-execution accuracy metrics, implemented a syntactic equivalence score, and refactored the evaluation logic to improve feedback for model tuning. Using Python, SQL, and pandas, he addressed bugs in SQL result comparison, error logging, and DataFrame handling, ensuring reproducible and reliable benchmark results. His work included adding optional caching to accelerate metric evaluation and refining error handling for clearer diagnostics. These contributions provided a robust foundation for ongoing analytics and model assessment efforts.
