新框架CLEAR通过关注可回答性来改进对话检索

作者 PulseAugur 编辑部 · [1 个来源] ·

研究人员开发了CLEAR，一个旨在通过关注可回答性而非仅仅话题相关性来改进对话检索系统的新框架。该框架利用蕴含蒸馏来训练一个重排器，以区分支持答案的段落和仅仅话题相关的段落。CLEAR还包含一个溯因召回模块，该模块使用LLM从段落中推断出潜在的可回答查询，从而扩大候选池。在TopiOCQA、QReCC和TREC CAsT等数据集上的实验表明，CLEAR的性能始终优于现有基线，尤其是在具有显著话题噪声的对话中。 AI

    从话题相关性到可回答性：对话式检索的蕴含蒸馏

    Existing conversational retrievers commonly treat topical relevance as a proxy for answerability. However, a passage that closely matches the dialogue context is not necessarily the one that supports the correct answer. We identify this mismatch as a systematic answerability gap.…
