Empathetic Dialogue Generation via Sensitive Emotion Recognition and Sensible Knowledge Selection

Understand

Empathy, which is widely used in psychological counselling, is a key trait of everyday human conversations.

• Equipped with commonsense knowledge, current approaches to empathetic response generation focus on capturing implicit emotion within dialogue context, where the emotions are treated as a static variable throughout the conversations.
• However, emotions change dynamically between utterances, which makes previous works difficult to perceive the emotion flow and predict the correct emotion of the target response, leading to inappropriate response.
• Furthermore, simply importing commonsense knowledge without harmonization may trigger the conflicts between knowledge and emotion, which confuse the model to choose incorrect information to guide the generation process.
