Consultation Through Role-Playing with a Character-Infused Dialogue System

Abstract

This paper reports on the control mechanisms and dialogue strategies adopted in the dialogue system developed for the Dialogue System Live Competition 7 (Situation Track). In this competition, participants were required to develop a system that listens to users' complaints and supports their decision-making. To effectively engage with users' grievances, it is essential to encourage self-disclosure. Therefore, in this study, we designed the system to exhibit a character personality commonly associated with the so-called "gal" archetype, which actively expresses positive and empathetic interest toward users. Furthermore, to assist users in making decisions, we incorporated a role-playing strategy aimed at fostering awareness and understanding of emotions. As a result, our system achieved sixth place in the competition's preliminary round.
