Graph RAG is an Knowledge-enabled RAG approach to retrieve information from Knowledge Graph on given task. Typically, this is to build context based on entities’ SubGraph related to the task.
GraphStore backed RAG vs VectorStore RAG
As we compared how Graph RAG helps in some use cases in this tutorial, it’s shown Knowledge Graph as the unique format of information could mitigate several issues caused by the nature of the “split and embedding” RAG approach.
