| Abstract(in English) | We are researching thought-evoking dialogue systems where conversation agents appropriately affect users and evoke their voluntary thoughts to motivate human communication. This paper proposes a thought-evoking quiz dialogue system using the Partially Observed Markov Decision Process (POMDP) that can treat such uncertain information as paralanguage information. As uncertain information, we employ the user's level of difficulty in handling quiz hints. Another person detects this difficulty level by observing the user's facial and voice information. The system controls the user's difficulty levels (easy, neutral, and difficult) for the hints by skipping hints based on the POMDP policy that was learned by reinforcement training. This paper evaluates the proposed system in simulation experiments. |
