Abstract

The rapid and incessant progress of language understanding and language generation capacity of large language models (LLMs) is followed by the discovery of new capabilities. The research community has to provide evaluation benchmarks to asses these emerging capabilities by studying, analysing and comparing different LLMs under fair and realistic settings. Question answering on tabular data is an important task to assess that lacks reliable evaluation benchmarks to assess LLMs in distinct scenarios, particularly for Spanish. Hence, in this paper we present Spa-DataBench, an evaluation benchmark composed of ten datasets about different topics of the Spanish society. Likewise, each dataset is linked to a set of questions written in Spanish and their corresponding answers. These questions are used to assess LLMs and analyse their capacity for answering questions that involve one single or multiple columns of different data types, and for generating source code to resolve the questions. We evaluate six LLMs on Spa-DataBench, and we compare their performance using both Spanish and English prompts. The results on Spa-DataBench show that LLMs are able to reason on tabular data, but their performance in Spanish is worse, which means that there is still room for improvement of LLMs in the Spanish language.
