Session Track: App Dev

Session Time: 04:00 pm - 04:30 pm November 6

Session description

In this session, you’ll get a hands-on tour of the LangChain Neo4j package, an open-source Python library for building GenAI applications on top of Neo4j. We’ll explore how to use Neo4jGraph for streamlined Cypher querying, leverage Neo4jVector for high-performance similarity and hybrid searches, persist conversational context with Neo4jChatMessageHistory, and power natural-language Q&A with GraphCypherQAChain. Along the way, you’ll see practical code snippets showing how you can use these tools to build powerful GenAI solutions with your knowledge graph.
