What Are They Achieving Through the Conversation? Modeling Guide-Tourist Dialogues by Extended Grounding Networks

s g F m Initiate Ack s u F m InitiateU AckG g Ack To engage conversations, especially those which have certain goals or tasks, the participants have to share many things to achieve collaboration. In each local interaction, the achievement of grounding (Clark and Schaefer, 1989; Clark and Brennan, 1991) about sharing each utterances meanings would be needed. By accumulating these grounding process, the final goal of the conversation would be accomplished. It is needed that both an evidence which the addressee would understand the speaker’s utterance is exhibited and they mutually share it. To develop a collaborative dialogue system, it is important that the system is designed to consider this grounding process. In this study, we propose a dialogue modeling method to deal with the grounding process between participants for goal-oriented dialogues.
