Building a Local Knowledge Graph RAG System for News Analysis with Neo4j and Ollama

Building a Local Knowledge Graph RAG System for News Analysis with Neo4j and Ollama

Short summary

NewsGraphRAG demonstrates how graph databases enable multi-hop reasoning for news analysis beyond traditional vector RAG. Built locally with Neo4j, Ollama, and spaCy NER, the system extracts entity relationships and answers complex queries by traversing knowledge graphs. This approach solves RAG's flat-retrieval limitation by tracing interconnected facts across multiple sources.

  • •Graph databases enable multi-hop reasoning that vector databases cannot
  • •Combines Neo4j, Ollama, and spaCy for local, free NER and retrieval
  • •Practical tutorial for building knowledge-graph RAG systems
