Novel chatterbot system utilizing Web information for estimating current user interests

Recently, the use of various chatterbots has been proposed to simulate conversation with human users. Several chatterbots can talk with users very well without a high-level contextual understanding. However, it may be difficult for chatterbots to reply to specific and interesting sentences because chatterbots lack intelligence. To solve this problem, we have proposed a novel chatterbot that can directly use Web information. In this paper, we propose a novel method of estimating current user interests to make conversation natural.
