MultiHiertt: Numerical Reasoning over Multi Hierarchical Tabular and Textual Data

Abstract: Numerical reasoning over hybrid data containing both textual and tabular content (e.g., financial reports) has recently attracted much attention in the NLP community. However, existing question answering (QA) benchmarks over hybrid data only include a single flat table in each document and thus lack examples of multistep numerical reasoning across multiple hierarchical tables. To facilitate data analytical progress, we construct a new large-scale benchmark, MULTIHIERTT, with QA pairs over Multi Hierarchical Ta… Show more

“…Fin-QA (Chen et al, 2021b) collects tables and context from financial domain, and raises financial-related questions including complex numerical reasoning. Multi-Hiertt (Zhao et al, 2022) and HiTAB (Cheng et al, 2021b) include numerical reasoning examples on hierarchical table question answering. For table fact verification tasks (Chen et al, 2019;Aly et al, 2021), the numerical reasoning skills are also required for verifying whether the given statement about the table is entailed or refuted.…”

“…Nevertheless, such pre-computed results can't cover answers requiring non-aggregation operations, e.g., question asking the difference(diff) of two cell values or asking the summation result(add) of certain cells with specific filtering condition. In fact, the proportion of non-aggregation operations is even higher in some of the numerical reasoning datasets (Zhu et al, 2021;Zhao et al, 2022;Chen et al, 2021b). Based on such observation, We find it necessary to extend the operation types for precomputed results, making it cover more operation types.…”
