Recently, social robots have get involved in human''s life, and these robots take the user''s feeling into account to friendly provide various services. In an aging society, we expect that a robotic caregiver is able to persuade an elderly person to perform a healthier behavior. In this work, pragmatic argument is adopted to make a user realize that an action is really worthwhile. Therefore, an adaptive recommendation dialogue system through pragmatic argumentation is proposed. There are three objectives in this work: first, we build a knowledge base for pragmatic argument construction, and the knowledge base concerns not only the effect of an action but also the reason for the effect; second, the robot is endowed with the ability to recommend an action that adopts to different users, and the recommended action is determined based on the integration of both robot''s and user''s value systems. In other words, the robot knows how to compromise with the user; third, the robot will persuade the user through his/her value system, and it will try to select the perspective whereby the user can be more interested in the action recommended by the robot. Finally, we invite 21 volunteers to participate in the experiment. The result has proved that the recommendation system has potential to affect the decision making of the user and help him/her have a healthier life.
