Too Long; Didn't ReadThis article explores the implementation of a "From Local to Global" GraphRAG pipeline using Neo4j and LangChain. It covers the process of constructing knowledge graphs from text, summarizing communities of entities using Large Language Models (LLMs), and enhancing Retrieval-...
