English(EN) PageRecall: Measuring Page Selection in Literature-Grounded Question Answering

新系统PageRecall衡量文献支持问答中的页面选择

研究人员开发了一个名为PageRecall的系统,用于衡量问答模型从研究论文中选择相关页面的有效性。该系统发现,证据的 grounding 受限于检索而非模型的阅读能力。具体来说,页面选择模型仅约一半时间能识别出正确的页面,并且当它未能找到正确页面时,通常会通过返回错误信息或不返回任何信息来默默失败。为解决此问题,研究人员提出在模型的上下文中显示整篇论文,这使得可解析论文的黄金页面召回率提高到100%。 AI

影响 这项研究突显了当前用于grounded QA的检索系统的局限性,并建议转向全上下文处理以提高准确性。

Source corroboration
Single-source cluster
Only one publisher covered this so far. Single-source stories can still rank when the publisher is high-authority, but they lack cross-source corroboration.

    PageRecall:衡量基于文献的问答中的页面选择

    We describe our system for LitTraceQA (GroundLM @ EMNLP 2026): given a research question, retrieve the relevant papers from a pool of 27,487, cite the page and the table or figure where the answer lives, and answer in a requested format. Our main finding is that evidence groundin…
