论文摘要
我们提出了Casper（Chat，Shift and Perform），这是一个由三种类型的对话模型组成的新颖对话系统：聊天，变速杆和表演者。用于主题切换的Shifter可以实现从开放域聊天到面向任务的对话框的无缝对话框。在一项用户研究中，卡斯珀（Casper）与以端到端方式训练的基线对话框系统相比，自然反应，缺乏强制性主题切换以及满意度给出了更好的印象。在一项消融研究中，我们发现与从Casper中删除变速杆相比，响应，对话满意度和任务引导率的自然性提高，这表明换档器的主题转移支持引入自然任务的对话框。
We propose CASPER (ChAt, Shift and PERform), a novel dialog system consisting of three types of dialog models: chatter, shifter, and performer. Shifter, which is designed for topic switching, enables a seamless flow of dialog from open-domain chat- to task-oriented dialog. In a user study, CASPER gave a better impression in terms of naturalness of response, lack of forced topic switching, and satisfaction compared with a baseline dialog system trained in an end-to-end manner. In an ablation study, we found that naturalness of response, dialog satisfaction, and task-elicitation rate improved compared with when shifter was removed from CASPER, indicating that topic shift with shifter supports the introduction of natural task-oriented dialog.
