Speaking at Google DevFest Bari 2026: Beyond Naive RAG with Knowledge Graphs and GraphRAG
On December 12, 2026, Fabio Montagna and I will be speaking at Google DevFest Bari 2026 with a 40-minute session titled:
Beyond Naive RAG: Grounding LLMs with Knowledge Graphs and GraphRAG in Action
Abstract
Classic RAG built solely on a Vector Database works well in demos, but quickly shows its limits in production: context fragmentation, inability to connect information distributed across multiple documents (multi-hop reasoning), and hallucinations when semantic similarity alone is not enough.
In this practical session, we will see how to overcome these limits by pairing vectors with the explicit structure of a Knowledge Graph.
Through code examples and an end-to-end demo, we will explore:
- The structural limits of Vector-only RAG and why embeddings alone lose domain relationships.
- Building a Knowledge Graph with LLMs: extracting entities and relationships from unstructured text, managing the MetaGraph (
Document -> Chunk -> Entity), and disambiguation. - GraphRAG Architecture and Hybrid Retrieval: combining Vector Index and graph traversal to provide the LLM with a rich, deterministic, and traceable context.
- Text2Cypher, Schema Injection, and AI Agent integration via the MCP (Model Context Protocol).
Attendees will walk away with concrete architectural patterns, queries, and ready-to-use code to turn a fragile RAG pipeline into a truly domain-aware system.
