Graph RAG
Graph RAG (Graph Retrieval-Augmented Generation) is an information retrieval and generation framework that combines knowledge graphs with retrieval-augmented generation (RAG) techniques. Its core mechanism involves constructing text corpora as graph structures—where nodes represent entities and edges represent relationships—and leveraging graph topology for multi-hop reasoning and relational information aggregation during retrieval. This approach addresses limitations of conventional RAG in handling complex relational queries and global semantic understanding, with retrieved results passed to a large language model to generate more accurate and contextually rich responses.
