“在机器阅读理解领域,处理和分析多方对话一直是一项具有挑战性的研究任务。鉴于中文语境下相关数据资源的缺乏,本研究构建了DialogueMRC数据集,旨在促进该领域的研究进展。DialogueMRC数据集作为首个面向中文多方对话的机器阅读理解数据集,包含705个多方对话实例,涵盖24451个话语单元以及8305个问答对。区别于以往的MRC数据集,DialogueMRC数据集强调深入理解动态的对话过程,对模型应对多方对话中的复杂性及篇章解析能力提出了更高的要求。为应对中文多方对话机器阅读理解的挑战,本研究提出了融合篇章结构感知能力的中文多方对话问答模型(DiscourseStructure-aware QA Model for Chinese Multi-party Dialogue,DSQA-CMD),该模型融合了问答和篇章解析任务,以提升对话上下文的理解能力。实验结果表明,相较于典型的基于微调的预训练语言模型,DSQA-CMD模型表现出明显优势,对比基于Longformer的方法,DSQA-CMD模型在MRC任务的F1和EM评价指标上分别提升了5.4%和10.0%;与当前主流的大型语言模型相比,本模型也展现了更佳的性能,表明了本文所提出方法的有效性。”
