arXiv:2507.21892v2 Announce Type: replace Abstract: Retrieval-Augmented Generation (RAG) mitigates hallucination in LLMs by incorporating external knowledge, but relies on chunk-based retrieval that lacks structural semantics. GraphRAG methods improve RAG by modeling knowledge as entity-relation graphs, but still face challenges in high construction cost, fixed one-time retrieval, and reliance on long-context reasoning and prompt design. To address these challenges, we propose Graph-R1, the first agentic GraphRAG framework via end-to-end reinforcement learning (RL). It introduces lightweight k
The increasing limitations of current Retrieval-Augmented Generation (RAG) approaches, particularly concerning structural semantics and fixed retrieval methods, necessitate more sophisticated solutions for enhancing LLM reliability.
This development represents a significant step towards more autonomous and context-aware AI systems, directly addressing hallucination while reducing resource costs in knowledge retrieval.
The introduction of an end-to-end reinforcement learning framework for GraphRAG enables more dynamic and adaptable knowledge retrieval, moving beyond static, chunk-based methods.
