This paper explores a novel approach to developing a dialogue system that is able to make entertaining conversations with users. It proposes a method to improve the current goal-driven dialogue systems which supportusers for specific tasks while satisfying users’goals with entertaining conversations. It then develops a dialoguesystem in which a set of features are considered to generate entertaining conversations, while reasonably prolonging the original too short dialogue. The game refinement measure is employed for the assessment of attractiveness since the conversations in dialogue systems can be seen as the process by which a player creates shoots or moves to win a game. The dialogues generated by the proposed method are evaluated by human subjects. The results confirm the effectiveness of the proposed method. The present idea can be a promising way to realize dialogue systems with entertaining conversations although further investigations are needed.
