Abstract (in Japanese) (See Japanese page) 
(in English) The state-of-the-art systems for chatting have a major problem of not being able to predict and utilize the user’s persona information well in a dialogue. Therefore, we propose a system that detects and predicts persona information from a utterance. The proposed system aims to improve the prediction performance of persona information by creating a persona information detector that uses Japanese-English machine translation. It detects sentences without persona information, which has been a cause of poor prediction performance of existing methods. We also created a persona information detector without machine translation to confirm the necessity of translation, and compared the results. The output of each method was manually evaluated, and the effectiveness of the proposed method was confirmed.
