ABSTRACT: LLMs are often like the know-it-all at a bar - they can quickly and confidently produce realistic sounding answers to just about any question - even if the answers are complete fabrications. But an LLM can be grounded in reality by combining it with a Knowledge Graph in order to prevent hallucinations, and to prevent unauthorized access to sensitive data.
This presentation will show you the benefits of Graph Databases over regular databases and how to use GenAI with RAG to eliminate hallucinations, enforce security, and improve accuracy. We will also discuss why a vector index plus Knowledge graph provides better, smarter, faster results than a pure vector database.
We will demonstrate an end-to-end retrieval pipeline. The code in the demo will be available in a Jupyter notebook on Github for you to reuse.

Andreas Kollegger is a technological humanist. Starting at NASA, Andreas designed systems from scratch to support science missions. Then in Zambia, he built medical informatics systems to apply technology for social good. Now with Neo4j, he is democratizing graph databases to validate and extend our intuitions about how the world works. Everything is connected.
