Built entirely for free and running fully locally on your machine, this project demonstrates how graph databases unlock multi-hop reasoning that traditional flat vector databases simply can't handle. By combining spaCy and Ollama (llama3.2) for a two-stage NER pipeline and using Neo4j's built-in vector index, the system extracts interconnected entities from news articles and successfull...
