| Abstract(in English) | A chat-oriented dialogue system can be more attractive if it can remember information about users and use that information during a dialogue. In this paper, we describe our development of a chat-oriented dialogue system that can remember user information(e.g., user's preferences etc.) acquired through dialogue. We also describe our experiment in which human users chat with the system for five consecutive days. In our experiment, three systems were compared: a system that can remember user information over multiple days, a system that can only remember user informationwithin a single dialogue session, and a system that does not remember any user information. As a result of the experiment that spanned five days, we found that, although there was little difference between the systems in terms of user satisfaction on the first day, as days went by, the user satisfaction of the system that can remember user information over multiple days became significantly better than other systems. |
