Abstract:

Natural language interaction systems have greatly simplified the interaction process between users and data analysis, allowing users to complete data analysis and chart generation through natural language. With the rise of large language models (LLMs), LLM-driven natural language data analysis systems have gradually become a trend in recent years. Thanks to their excellent logical reasoning and tool invocation capabilities, LLMs are able to generate more complex logical inferences and charts. However, interactive data analysis based on LLMs poses challenges. Data analysts must clearly define the direction of analysis to drive the interactive process, which often necessitates a deep understanding of the data. Furthermore, when employing LLMs for data exploration, analysts are often less directly involved with the data, which may lead to insufficient understanding of the data and consequently affect the overall control of the analysis process. To assist users in clarifying the analysis process and deepening their understanding of the data, the LLM-based recommendation and association-driven data analysis system DRec was proposed. This system aided users in developing a comprehensive understanding of the data through associative information and guides the data analysis process. At the same time, the system provided insights from both the semantic and data dimensions and offered query recommendations to assist users in determining the analysis direction. Case studies and user experiments demonstrated that the DRec system can enhance data analysis interaction efficiency and guide users toward reasonable data analysis results.
