New AI model MLDocRAG solves long multimodal document understanding

Researchers have introduced MLDocRAG, a new framework that dramatically improves AI's ability to understand long, complex documents containing mixed text, figures, and tables. It uses a novel 'Multimodal Chunk-Query Graph' to link related information across different formats and pages, acting as a semantic map. In tests on MMLongBench-Doc and LongDocURL datasets, it consistently boosted retrieval quality and answer accuracy for long-context Q&A.
