ChatBI: Towards Natural Language to Complex Business Intelligence SQL

Central Theme

ChatBI is a proposed AI system that enhances natural language to business intelligence (NL2BI) by focusing on interactive, multi-round dialogues. It addresses challenges in converting natural language to complex SQL, using a smaller model, view technology for schema linking, and a phased process flow. This approach improves accuracy, particularly for handling complex semantics and comparison relations, making it suitable for large-scale production. Compared to existing NL2SQL methods, ChatBI demonstrates better performance in practical BI scenarios, such as analyzing video views and playtime. The system differentiates itself by employing virtual columns, decomposing tasks, and leveraging LLMs more efficiently, outperforming baselines like DIN-SQL and MAC-SQL in useful execution accuracy.
