| Abstract: |
| The current dialogue system can be sensitive to the emotions in the user's words, generating an empathetic response to help calm the user's emotions. But in some cases, eliciting empathetic responses may not adequately mitigate the adverse effects that the current conversation topic is having on users. The dialogue system will continue the conversation with the user under this uncomfortable topic, which will lead to a worse chat situation or even an impasse. To solve this problem, a dialogue system that can change the topic autonomously according to the user's emotions is proposed in this paper. Specifically, the dialogue system first collects the emotional semantic information of the users and then detects it according to the emotion classification module. Once the detection results show that the user is in a bad mood, the topic change module selects a new topic from the context to shift to and generates a response . This not only helps to calm the user's mood but also move the conversation to a new area, steering the user away from the uncomfortable topic. The experimental results show that the proposed method incurs less cost in terms of content quality, but improves the emotional perception ability. Additionally, it endows the dialogue system with the ability to change the topic, and improves the user's dialogue experience. |
