Researchers have developed a novel multimodal graph-based retrieval-augmented generation (RAG) approach to enhance the understanding of long, visually rich documents. This method addresses the limitations of current multimodal large language models (MLLMs) and multimodal RAG (MMRAG) systems, which struggle with holistic comprehension due to restricted context windows. By integrating knowledge graphs (KGs) that summarize global document information, the new approach aims to improve visual question answering (VQA) capabilities. The researchers also introduced a new benchmark, DLVQA, to facilitate the evaluation of document-level VQA performance, demonstrating that their method surpasses existing MMRAG and KG-based techniques.
