A Study on Dialogue Systems by Emotion Analysis and Emotional Expression

Abstract

We live with a variety of stresses in our daily lives. One way to release these stresses is to have others listen to our complaints. However, depending on one’s living environment, there may be no one close at hand to listen to one’s complaints. We attempt to solve this problem by using a dialogue system. Tsuboi’s previous approach involved creating a system that responded with interjections and parroting back the user’s statements. This system was examined to see if it could reduce stress. However, it was found that due to the limited response patterns and content, the system felt impersonal. In this paper, we propose to enhance Tsuboi’s system by increasing the variety of interjections and responses, and by adding methods for emotional expression based on emotional analysis.
