ConRAG：面向多跳问答的共识驱动证据流框架
ConRAG: Consensus-Driven Evidence Flow for Multi-Hop Question Answering
AI 导读
针对多跳 RAG 的证据选择与信息传递难题，研究者提出 ConRAG 框架，通过共识驱动的多视角排序筛选相关证据，并用槽位机制在依赖推理步骤间传递中间信息。在三个多跳问答基准上，ConRAG 于 Gemma-4-31B-it 上平均分超越最强基线 5.8 分，端到端运行时间与 token 消耗分别降低 75.9% 和 67.3%。

Abstract:Retrieval-augmented generation (RAG) has emerged as a promising paradigm for enhancing large language models (LLMs) on multi-hop question answering (QA), which requires reasoning over evidence from multiple documents. However, current multi-hop RAG approaches still struggle with evidence selection and information transfer, i.e., retrieving irrelevant passages or failing to pass intermediate information to subsequent reasoning steps, thereby hindering coherent multi-hop reasoning. To this end, we propose ConRAG, a consensus-driven evidence flow framework that effectively boosts LLM performance on complex multi-hop QA. In short, the core of ConRAG is to select relevant evidence via consensus-driven multi-view ranking, and leverage a slot-based mechanism to transfer intermediate information between dependent reasoning steps. Extensive experiments across three multi-hop QA benchmarks show that ConRAG surpasses the baselines by a clear margin. Encouragingly, on Gemma-4-31B-it, ConRAG outperforms the strongest baseline by 5.8 points in average score, while reducing total end-to-end runtime and token consumption by 75.9% and 67.3%, respectively.
