Human-likeness of dialogue systems is an important,rnalbeit neglected issue. In this paper, basing on evaluationrnexperiments of humor-equipped chatterbot, we propose arnmethod of measuring the distance between humans andrnsystems and relation between human-likeness and humor.rnThe results show that the presence of humor can enhancernthe performance of dialogue systems. A humor-equippedrnchatterbot was evaluated as more human like andrngenerally better than one without humor, by both first andrnthird person evaluators. The implications of this fact andrnnovelty of evaluation method are discussed, and somernideas for the future are given.
