Graph-Based Retrieval-Augmented Generation: Applications, Challenges, Solutions, and Opportunities

Summary: Tutorial on graph-based RAG that surveys applications, challenges, and methods. Reframes RAG as a data-management pipeline—graph modeling/repair, index maintenance, and retrieval—and highlights multimodal extensions and open directions. (summarized by gpt-5.6-luna on Aug 28 2026)
