Graph RAG

GraphRAG is a technique proposed by Microsoft Research to generate knowledge graphs from text using LLMs. This project is an implementation of GraphRAG in Python. It makes it simple to get up and running with GraphRAG and generate knowledge graphs from text. It also provides a semantic search interface to query the knowledge graph.
