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 successfully traverses relationship paths to answer complex queries with high traceability. <br> Check out my latest project exploring local GraphRAG systems:</p> <div class="ltag-github-readme-tag"> <div class="readme-overview"> <h2> <img src="https://assets.dev.to/assets/github-logo-5a155e1f9a670af7944dd5e12375bc76ed542ea80224905ecaf878b9157cdefc.svg" alt="GitHub logo"> <a href="https://github.com/emineksknc" rel="noopener noreferrer"> emineksknc </a> / <a href="https://github.com/emineksknc/newsgraphrag" rel="noopener noreferrer"> newsgraphrag </a> </h2> <h3> </h3> </div> <div class="ltag-github-body"> <div id="readme" class="MD"><div class="markdown-heading"> <h1 class="heading-element">Building a Local Knowledge Graph RAG System for News Analysis with Neo4j and Ollama</h1> </div> <p><em>How graph databases unlock multi-hop reasoning that vector databases simply can't do — built entirely for free, running entirely on your machine</em></p> <div class="markdown-heading"> <h2 class="heading-element">The Problem with Traditional RAG</h2> </div> <p>Imagine you ask your news analysis system: <em>"What is the connection between Elon Musk and Sam Altman?"</em></p> <p>A traditional RAG system backed by a vector database will search for the most semantically similar chunks and likely return one article — maybe the xAI launch, or maybe the OpenAI board crisis. But the full answer spans both, and more.</p> <p>The complete picture is spread across multiple articles:</p> <ul> <li>Article 1: Musk and Altman co-founded OpenAI, Musk departed the board in 2018</li> <li>Article 2: Altman was fired and reinstated as CEO during the board crisis</li> <li>Article 3: Musk launched xAI and later sued OpenAI, alleging it had abandoned its non-profit mission</li> </ul> <p>The…</p></div> </div> <div class="gh-btn-container"><a class="gh-btn" href="https://github.com/emineksknc/newsgraphrag" rel="noopener noreferrer">View on GitHub</a></div> </div> ai showdev opensource rag
