Vector-RAG vs. Graph-RAG — Multi-Hop & Multi-Needle Experiment Controlled comparison of three retrieval pipelines over the same chunk corpus, same reader LLM, same prompts, differing only in retrieval strategy: Pipeline Retrieval vector Dense retrieval (bge-large-en-v1.5, cosine, top-5) traversal KG entity-match on question → 2-hop graph traversal, chunks ranked by 1/(1+hop) ppr Personalized PageRank with teleport to question entities (HippoRAG-style), max-score… See the full description on the dataset page: https://huggingface.co/datasets/SGK86/rag-vs-graphrag-eval.
