Abstract
In order to deal with increasingly complex issues such as environmental issues, high-quality discussions need to be held widely. The discussion quality index DQI is often used in studies that focus on discussion utterances, but there are challenges in applying it to domestic cases. Therefore, in this study, we first presented a methodology to address these issues. Then, through case studies, we attempted to characterize the utterances that trigger high-quality discussions using factor analysis techniques. The results suggested that these utterances have characteristics that emphasize maintaining communication, such as consideration and empathy for the other person's feelings, and being careful about one's appearance. Although it is necessary to accumulate more case studies in the future, we were able to present the methodology this time.
