| Abstract(in English) | Recently, computerized dialogue systems are researched and used in various fields. In order to realize a practical system, the performance should be evaluated quantitatively. The objective and quantitative evaluation method for dialogue systems for reservation services has already been established, non-task-oriented dialogue systems, however, have been evaluated only by subjective method, like a questionnaire. In this paper, we propose a new criterion which can evaluate non-task-oriented dialogue systems objectively and quantitatively. We assume a human-human dialogue is an ideal dialogue. We build a HMM by learning a sequence of human-human dialogue utterance tag which is automatically assigned. We apply 2-gram for auto-tagging and evaluate naturality of a dialogue using HMM. In this simulation, a correct rate applying auto-tagging is 71%. If we relax semantic conditions, a correct rate is 87%. It was clarified that a HMM method can evaluate the naturality of dialogue systems. |
