SciTaRC: Benchmarking QA on Scientific Tabular Data that Requires Language Reasoning and Complex Computation

arXiv cs.CL / 3/11/2026

Ideas & Deep AnalysisModels & Research

Key Points

  • SciTaRC is a newly introduced expert-authored benchmark designed to evaluate AI performance on questions involving tabular data from scientific papers, emphasizing deep language reasoning and complex computation.
  • Current state-of-the-art AI models, including powerful open-weight models like Llama-3.3-70B-Instruct, exhibit significant failure rates on SciTaRC, with at least 23% of questions answered incorrectly overall and up to 65.5% failure on certain tasks.
  • The study identifies a pervasive 'execution bottleneck' where both code-based and language models fail to execute reasoning plans reliably, attributable to brittleness with raw scientific tables and comprehension and calculation errors in natural language reasoning.
  • This benchmark highlights critical limitations in AI models’ ability to perform accurate reasoning and computation on scientific tabular data, signaling areas for future research and improvements in model reasoning capabilities.

Abstract:We introduce SciTaRC, an expert-authored benchmark of questions about tabular data in scientific papers requiring both deep language reasoning and complex computation. We show that current state-of-the-art AI models fail on at least 23% of these questions, a gap that remains significant even for highly capable open-weight models like Llama-3.3-70B-Instruct, which fails on 65.5% of the tasks. Our analysis reveals a universal "execution bottleneck": both code and language models struggle to faithfully execute plans, even when provided with correct strategies. Specifically, code-based methods prove brittle on raw scientific tables, while natural language reasoning primarily fails due to initial comprehension issues and calculation errors.
