NODES AI 2026 - EventKernel: Multi-Hop Reasoning and GraphRAG for AI-Powered Event Intelligence

This talk features Divakar Kumar at NODES AI, focusing on "EventKernel: Multi-Hop Reasoning and GraphRAG for AI-Powered Event Intelligence." The session discusses the limitations of semantic search when handling complex, nuanced inquiries and proposes a solution through the integration of vector search, knowledge graphs, and multi-hop reasoning. Attendees will gain insights into how EventKernel, built on Neo4j, interprets user queries into hybrid retrieval flows, including vector-only and GraphRAG approaches, while emphasizing explainability and performance in AI systems. The speaker highlights techniques for structuring queries dynamically and blending embeddings with graph traversals to enhance the user experience.
