Evidence passages are specific excerpts or segments of text retrieved from reference documents that contain the factual information necessary to substantiate, verify, or refute a claim, statement, or answer. In natural language processing, information retrieval, and automated question answering, these text snippets serve as authoritative grounding for generated responses, enabling users and evaluation systems to trace assertions back to their underlying sources. By directly presenting the relevant context from a larger body of work, evidence passages facilitate the assessment of factual accuracy, source attribution, and reliability in knowledge-intensive tasks.
