Researchers have introduced VELD-QA, a new large-scale benchmark designed to evaluate visual evidence grounding and question answering capabilities within lengthy documents. This benchmark comprises 15,000 human-authored question-answer pairs derived from 5,859 real-world PDFs, totaling over 370,000 pages. VELD-QA includes detailed annotations for supporting pages and visual elements, allowing for separate assessment of retrieval and interpretation skills. Evaluations of nine vision-language models and seven retrieval-augmented systems revealed significant challenges in evidence localization and interpretation, indicating that even with full document access, performance remains limited.
