TopBench: A New Benchmark for Evaluating Large Models' Table Reasoning Capabilities

TopBench is a new benchmark for implicit prediction and reasoning tasks in table question answering, consisting of 779 samples covering four task types: single-point prediction, decision-making, treatment effect analysis, and complex filtering. It aims to systematically evaluate the performance of large models on such complex tasks, reveal the limitations of current models, and provide a standardized evaluation platform for related research and applications.

Large language models have made significant progress in the field of table question answering, but traditional queries are mostly information extraction or simple aggregation. Real-world data analysis often involves implicit predictive queries, requiring models to infer unobserved answers based on historical patterns, which brings two core challenges: identifying potential intentions and reliable predictive reasoning.

TopBench contains 779 carefully annotated samples covering four subtasks: 1. Single-point prediction (inferring missing cell values); 2. Decision-making (selecting the optimal solution based on data); 3. Treatment effect analysis (causal reasoning to evaluate intervention effects); 4. Complex filtering (screening data subsets according to implicit conditions).

The research team evaluated pure text models and agent workflow architectures and found: 1. Most models default to simple lookup and fail to recognize predictive intentions; 2. Accurate intent disambiguation is a prerequisite for predictive reasoning; 3. Even with correct intentions, the prediction accuracy of models still has an upper limit, requiring the integration of more complex modeling techniques.

Agent workflows, by decomposing tasks into steps such as pattern recognition and hypothesis generation, show more stable performance than single-step generation, but their effectiveness is highly dependent on the intent understanding ability of the underlying model.

TopBench provides evaluation standards for multiple fields: Business intelligence tools can develop predictive analysis assistants; Financial analysis scenarios (risk assessment, investment prediction) require implicit reasoning capabilities; Clinical decision support systems in healthcare need to predict treatment effects—all of which are closely aligned with the task design of TopBench.

TopBench fills a gap in the evaluation system for large models, serving both as a yardstick to measure progress and a roadmap for future research. As the structured data reasoning capabilities of large models improve, we look forward to the emergence of more intelligent systems for in-depth predictive analysis.
