GraphRAG, a new method developed by Microsoft Research, enhances retrieval-augmented generation (RAG) by utilizing knowledge graphs instead of just text chunks. This approach allows LLMs to answer complex, multi-hop questions that require connecting information across multiple documents, which traditional flat vector RAG struggles with. GraphRAG indexes entities as nodes and relationships as edges, enabling graph traversal for detailed answers and community summarization for broader queries, though it incurs an upfront cost for indexing.
