Overview
This codelab walks you through building a GenAI-powered movie recommendation chatbot using the GraphRAG approach. You’ll learn how to create a Knowledge Graph using Neo4j, generate vector embeddings with Vertex AI’s text embedding models, and build a conversational chatbot powered by Gemini. The chatbot combines semantic search with LLM-generated Cypher queries to perform deeper reasoning over the graph and return contextual, explainable movie recommendations based on natural language input.
