本文系统性综述了以非结构化文本作为外部知识源的开放域对话系统(UTEDS),定义了相关概念,总结了数据集与模型,将其分为检索与生成模型并剖析组件,探讨了评估方法与未来趋势。

摘要:

将外部知识融入对话生成已被证明有益于开放域对话系统(DS)的性能,例如生成信息丰富或具有特定风格的回复,以及控制对话主题。在本文中,我们研究以非结构化文本作为外部知识源的开放域DS(非结构化文本增强对话系统,UTEDS)。非结构化文本的存在使得UTEDS有别于传统的数据驱动DS,我们旨在分析这些差异。我们首先给出UTEDS相关概念的定义,然后总结近期发布的数据集和模型。我们将UTEDS分为检索模型和生成模型,并从模型组件的角度进行介绍。检索模型由融合、匹配和排序模块组成,而生成模型包含对话与知识编码、知识选择和回复生成模块。我们进一步总结了UTEDS中使用的评估方法,并分析了当前模型的性能。最后,我们讨论了UTEDS的未来发展趋势,希望能为该领域的新研究提供启发。

英文摘要:

Incorporating external knowledge into dialogue generation has been proven to benefit the performance of an open-domain Dialogue System (DS), such as generating informative or stylized responses, controlling conversation topics. In this article, we study the open-domain DS that uses unstructured text as external knowledge sources (\textbf{U}nstructured \textbf{T}ext \textbf{E}nhanced \textbf{D}ialogue \textbf{S}ystem, \textbf{UTEDS}). The existence of unstructured text entails distinctions between UTEDS and traditional data-driven DS and we aim to analyze these differences. We first give the definition of the UTEDS related concepts, then summarize the recently released datasets and models. We categorize UTEDS into Retrieval and Generative models and introduce them from the perspective of model components. The retrieval models consist of Fusion, Matching, and Ranking modules, while the generative models comprise Dialogue and Knowledge Encoding, Knowledge Selection, and Response Generation modules. We further summarize the evaluation methods utilized in UTEDS and analyze the current models' performance. At last, we discuss the future development trends of UTEDS, hoping to inspire new research in this field.
