Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we propose a response generation method for dialogue systems that uses the user's lifelog to estimate the user's emotions in order to realize empathic dialogue. The lifelog stores the user's daily actions, experiences and the emotional polarity of whether the user felt positive or negative about those experiences. Using lifelog makes it possible not only to use user-specific information in dialogues, but also to appropriately estimate user's emotions. First, we compared the accuracy of emotion polarity estimation with or without user-specific information in lifelog. As a result, we showed better performance of the proposed method; i.e., the estimation accuracy of the emotional polarity with lifelog was 0.856, but that of without lifelof was 0.699. Second, we found that the user's life pattern affects daily changes in the accuracy of the estimation of the emotional polarity.
