Abstract

<p>Local governments have high expectations for dialogue systems that provide residents and visitors with dialogue on multiple tasks, such as tourist information, town office information, and daily life information. In addition, there is also an expectation for such dialogue systems to be given the personalities of characters possessed by local governments and to provide chat dialogues for residents. However, to give the personality of a character to the dialogue system, task dialogue data and dialogue manager that reflect the personality are essential. Based on the study of role play-based question-answering dialogue systems that reproduce characters, we propose a method for collecting dialogue data that enables task dialogue and a method of dialogue manager and response selection that facilitates task dialogue. We constructed a dialogue system that imitated a certain local government character using the proposed method and evaluated its effectiveness through a laboratory experiment and demonstration experiment. The results showed that our dialogue system had statistically better performance in both task-oriented dialogue and chat oriented one.</p>
