Multi Hop Reasoning Evaluation Across Document Sections

via “compositional reasoning benchmark with multi-document retrieval requirements”

113K questions requiring multi-hop reasoning across Wikipedia articles.

Unique: Explicitly validates that questions require multi-hop reasoning through crowdsourced verification that single-document retrieval cannot answer them. Questions are structured around entity linking and relationship composition, forcing systems to perform genuine multi-stage reasoning rather than single-stage retrieval.

vs others: Compared to general QA datasets like Natural Questions (single-hop, web-scale) or SQuAD (single-document), HotpotQA's explicit multi-hop requirement and supporting fact annotations make it uniquely suited for evaluating whether systems perform compositional reasoning vs. pattern matching.
