本研究では,対話型擬人化エージェントの受容性について,日米比較の観点で議論する.具体的に,「調査1:社会に進出するロボットとの対話に関する受容性のオンライン調査」および「調査2:対話型擬人化エージェントとの対話を想定した言語的配慮の印象評価」を実施する.調査1では,固有の擬人化エージェントを指定せず,社会に参画するロボット全体に対して抱いている否定的態度と不安印象を評価する.調査2では,対話型擬人化エージェントと対話する想定の動画を実験参加者に視聴してもらい,その印象を評価する.これらの調査の結果,アメリカ人参加者は擬人化エージェント全体に対する否定的態度や不安な印象が日本人参加者より強い傾向にあったが,その一方で擬人化エージェントと疑似的な対話を行なうシチュエーションにおいてアメリカ人参加者に対する受容性を日本人参加者よりも高めることが可能であることが示唆された.

In this paper, we investigate the acceptability of a non-task-oriented dialogue system that uses utterances to get closer psychologically. We defined utterances to get closer psychologically as “utterances that express intimacy with the other person or a favorable feeling toward the other person, such as joking, sympathy, compliment, or non-honorifics utterances (like a friend)”. Conventional research has reported that jokes, non-honorifics utterances, and compliments are useful for building a smooth relationship between a dialogue system and a user. On the other hand, individual differences in acceptability to utterances to get closer psychologically are considered to be large. In particular, we believe that the personality characteristics of the user affect the acceptability of utterances to get closer psychologically. So, we set research question 1: “How do user personality traits affect the acceptability of a non-task-oriented dialogue system with utterances get closer psychologically?” Also, utterances get closer psychologically has the risk of making the interlocutor uncomfortable. Therefore, in considering the implementation of utterances gets closer psychologically in a dialogue system, it is useful to examine how different strategies of utterances get closer psychologically affect the acceptability of a chatting dialogue system. So, we set research question 2: “How do different utterance strategies to get closer psychologically affect the acceptability of chatting dialogue systems?” To discuss these research questions, we conducted a dialogue experiment using a rule-based non-task-oriented dialogue system (n = 82). The results showed that for RQ1, among the five personality characteristics targeted in this experiment, the user’s diligence was related to the evaluation of the non-task-oriented dialogue system for utterance strategies to get closer psychologically used in this experiment in the subjective index, and extroversion, neurotic tendency, and openness in the objective index (likability based on user utterances). For research question 2, the experimental results showed that the acceptability between utterance strategies to get closer psychologically was significantly different in the viewpoint of the subjective index. These findings contribute to the design of a non-task-oriented dialogue system.

In this paper, we propose the “Risky Politeness Strategy (RPS)” as a framework of utterance strategy focusing on risk-taking in dialogue systems. In previous research, it has been reported that it is useful to implement politeness strategies that have risks such as jokes and compliments in dialogue systems. On the other hand, a design theory for effectively implementing risk-taking utterance strategies in dialogue systems has not been established. Against this background, we defined RPS with reference to politeness/impoliteness research in the fields of linguistics. In addition, we developed a rule-based dialogue system and an example-based dialogue system to implement the RPS in a non-task-oriented dialogue. User evaluations were conducted through the preliminary rounds of the Dialogue System Live Competition 2 and 3. The results of the user evaluations showed that the rule-based and example-based RPS-speaking non-task-oriented dialogue systems were able to engage in dialogue that was evaluated by the user as having humanity. Therefore, the usefulness of implementing RPS in non-task-oriented dialogue systems has been shown at a certain level.
