Effectiveness of dialog contents for obtaining personal attribute

摘要

It looks easy to make human relationship, but it is difficult because of various factors. Moreover, it is difficult to continue a dialog with those who have never met before. Dialogs aren't continued without pleasant topics. However, if pleasant topics are understood, dialogs are continued and he/she wants to talk about himself/herself. It is supposed to be applied to dialog with robot as well. If robots understand user's favorite topics and make a fit dialog for user, user may talk with robot aggressively. However, existing dialog systems have not encouraged users to talk. We develop a chat system in order to resolve the difficulty. The experiment was carried out to evaluate the system. It is important that dialog systems need to change dialogs in order to let users to talk. This paper describes chat system with robot to obtain user's information.
