Player type classification based on activity logs in a gamified seminar setting

University laboratory seminars provide a good opportunity for a presenter and other participants to discuss academic subject matter. In our laboratory, we have integrated a gamification technique into our seminar recording system and have developed and operated a Gamified Discussion system that sustains and improves the motivation of students to actively participate in seminars and stimulates discussions by evaluating and visualizing the argumentative skills of students. However, classification of a participant's type is essential to the improvement of the system and detailed analyses of motivation. Here, we report the results of clustering for player type classification using activity logs collected from the system.
