Researchers have developed VLD-RAG, a novel agentic framework designed for retrieval-augmented generation over long, visually-rich documents. This system constructs a multimodal index that preserves page layout and incorporates both textual and visual signals. By employing a hybrid retrieval strategy combining keyword and semantic search, VLD-RAG identifies relevant evidence pages and utilizes a coordinated agent workflow for evidence gathering, citation verification, and iterative refinement of retrieval requests. Evaluations on benchmarks like LongDocURL and MMLongBench-Doc demonstrate VLD-RAG's superiority in both evidence retrieval and question answering accuracy compared to existing vision-based methods.
