摘要:
信息检索(IR)评估仍然具有挑战性,因为不完整的IR基准数据集包含未标记的相关片段。尽管LLM和LLM-人类混合策略减少了昂贵的人力努力,但它们仍然容易产生LLM过度自信和无效的AI-人类升级。为此,我们提出了DREAM,一个基于多轮辩论的相关性评估框架,基于对立的初始立场和迭代相互批评。通过我们的协议辩论,它在某些情况下产生更准确的标签,在不确定的情况下产生更可靠的AI-人类升级,实现了95.2%的标签准确率,仅需3.5%的人力参与。使用DREAM,我们构建了BRIDGE,一个经过改进的基准,通过揭示29,824个缺失的相关片段来减轻评估偏差,并通过公平的检索器比较来启用更公平的检索器比较。然后我们重新基准测试IR系统,并将评估扩展到RAG,表明未解决的漏洞不仅扭曲了检索器排名,还驱动了检索生成的不一致。相关性评估框架可在https://github.com/DISL-Lab/DREAM-ICLR-26上获得;BRIDGE数据集可在https://github.com/DISL-Lab/BRIDGE-Benchmark上获得。
英文摘要:
Information retrieval (IR) evaluation remains challenging due to incomplete IR benchmark datasets that contain unlabeled relevant chunks. While LLMs and LLM-human hybrid strategies reduce costly human effort, they remain prone to LLM overconfidence and ineffective AI-to-human escalation. To address this, we propose DREAM, a multi-round debate-based relevance assessment framework with LLM agents, built on opposing initial stances and iterative reciprocal critique. Through our agreement-based debate, it yields more accurate labeling for certain cases and more reliable AI-to-human escalation for uncertain ones, achieving 95.2% labeling accuracy with only 3.5% human involvement. Using DREAM, we build BRIDGE, a refined benchmark that mitigates evaluation bias and enables fairer retriever comparison by uncovering 29,824 missing relevant chunks. We then re-benchmark IR systems and extend evaluation to RAG, showing that unaddressed holes not only distort retriever rankings but also drive retrieval-generation misalignment. The relevance assessment framework is available at https: //github.com/DISL-Lab/DREAM-ICLR-26; and the BRIDGE dataset is available at https://github.com/DISL-Lab/BRIDGE-Benchmark.
