LangChain Neo4j
LangChain Neo4j is the integration between LangChain framework and Neo4j graph database that enables natural language interaction with knowledge graphs through AI-powered applications. Neo4j is a graph database management system developed by Neo4j, Inc. The data elements Neo4j stores are nodes, edges connecting them, and attributes of nodes and edges. The broad and deep Neo4j integration allows for vector search, cypher generation and database querying and knowledge graph construction. This combination supports GraphRAG applications, Cypher query generation from natural language, vector similarity search, and hybrid retrieval systems that leverage both structured relationships and semantic embeddings for enhanced AI applications requiring complex data relationships and contextual understanding.
