HopRAG: Multi-Hop Reasoning for Logic-Aware Retrieval-Augmented Generation

A novel RAG framework that augments retrieval with logical reasoning through graph-structured knowledge exploration.

The paper proposes HopRAG, a framework that constructs a passage graph and employs a retriever-reason-prune mechanism to identify relevant passages based on logical connections. Experiments demonstrate improved final answer quality on multi-hop benchmarks. The framework expands the retrieval scope by exploring multi-hop neighbors guided by pseudo-queries and LLM reasoning.
