The user interface based on natural language dialog has been gathering attention. In this paper, we focus on the dialog-based user interface of movie recommendation system. We compared two kinds of dialog systems: the system-initiative system presented all the information about the recommended item at a time, and the user-initiative system provided information of the recommended item based on a dialog between the system and the user. As a result of dialog experiment, the users preferred to the user-initiative system for availability of obtaining required information, while the system-initiative system was chosen for the simplicity of obtaining the information. In addition, it was found that the appropriateness of the system’s replies in the dialog affected the user’s preference to the user-initiative system.
