Abstract

Emotion is an important factor to the success of conversational agents or chatbot. Existing chatbots have been shown to be good for generating natural responses. However, they still lack mechanisms to integrate emotional information. In this paper, we propose an approach that can produce emotion-specific responses by encoding emotional information into sequence-to-sequence model. The experimental results show that the proposed model generates responses appropriate to content and emotion. Specifically, this model improves up to 10% in emotional precision and 50% BLEU score compared to the baseline.
