TopBench: A Benchmark for Implicit Predictive Reasoning in Tabular Question Answering

arXiv:2604.28076v2 Announce Type: replace-cross Abstract: Large Language Models (LLMs) have advanced Table Question Answering, where most queries can be answered by extracting information or simple aggregation. However, a common class of real-world queries is implicitly predictive, requiring the inference of unobserved answers from historical patterns rather than mere retrieval. These queries introduce two challenges: recognizing latent intent and reliable predictive reasoning over massive tables. To assess LLMs in such Tabular questiOn answering with implicit Prediction tasks, we introduce To

Why this matters
Why now

The rapid advancement of LLMs necessitates benchmarks for more complex reasoning tasks beyond simple retrieval, pushing the boundaries of their real-world applicability.

Why it’s important

This benchmark addresses a critical limitation of current LLMs by testing their ability to perform implicit predictive reasoning, essential for real-world analytical tasks over structured data.

What changes

The development of 'TopBench' provides a standardized evaluation metric that will drive the development of LLMs capable of more sophisticated data understanding and predictive analytics.

Winners
  • · AI model developers
  • · Data analytics platforms
  • · Enterprise AI users
  • · Research institutions
Losers
  • · LLMs with only retrieval capabilities
