Personality customization of chatbots using ChatGPT

Abstract

In recent years, the use of chatbots has been rapidly expanding in corporate inquiry handling and mental health care applications. In particular, chatbot personality in user interaction has attracted attention as a factor that significantly influences user satisfaction and engagement. In this study, we propose a method to customize chatbot personalities by combining multiple base characters based on 16 types of classification by MBTI using ChatGPT. Through evaluation experiments, we verified the degree to which the personalities reproduced by the combination of base characters match the pre-defined target personalities.
