GraphRAG Analysis, Part 1: How Indexing Elevates Knowledge Graph Performance in RAG

TLDR:Knowledge graphs may not significantly impact context retrieval — all knowledge graph RAG methods I examined showed similar context relevancy scores to those of FAISS (~0.74). Neo4j withOUT its own index achieves a higher answer relevancy score (0.93) but an 8% lift over FAISS may not be worth the ROI constraints. This score is compared to Neo4j WITH index (0.74) and FAISS (0.87), suggesting
