English(EN) Explaining When PRF Fails: Participatory Auditing for Selective Query Expansion

新框架使用LLM和用户反馈审计信息检索中的PRF

一篇新的研究论文提出了一个两阶段框架来解决信息检索中伪相关反馈(PRF)的不透明性。该框架首先涉及108名用户的参与式审计,结果显示PRF仅使约20.9%的查询受益,而对25.6%的查询产生负面影响。第二阶段利用基于LLM的重排器自动预测用户派生的标签,从而能够对PRF决策进行可扩展的检查。这种方法旨在将PRF从一个不透明的组件转变为一个可审计的、以用户为基础的系统。 AI

影响 这项研究通过改进PRF的应用方式,有可能带来更透明、更有效的信息检索系统。

    解释PRF何时失效:选择性查询扩展的参与式审计

    Pseudo-Relevance Feedback (PRF) improves retrieval effectiveness on average, but harms a substantial fraction of queries through query drift, an asymmetry hidden by aggregate offline metrics. Existing Selective PRF (sPRF) approaches typically rely on Query Performance Prediction …
