HybridRAG: Integrating Knowledge Graphs and Vector Retrieval Augmented Generation
BlackRock & NVIDIA researchers propose HybridRAG — combining Knowledge Graph RAG (GraphRAG) with Vector RAG for financial document Q&A. The hybrid approach outperforms either method alone on earnings call transcripts, achieving higher answer relevancy and faithfulness because graph structure captures entity relationships that vector search misses.
