Summary:
Recently, the computer aided communication have been actively studied. One of them is the study of dialogue agent. However, There are few researches on the systems to talk with a human, and there are no systems that can make an intellectual reply. In order to realize a practical system, the performance should be evaluated quantitatively. In this paper, we propose a new method that is based on the presumption that a utterance is semantically correct if it has lexical cohesion among a context. It was clarified that our method can evaluate performance of dialogue system objectively and quantitatively.
