Outline of Final Research Achievements

In this study, to model the dialogue strategies of the experts such as professional tour guides we tried to construct the framework structuring the discourse by regarding the execution of discourse as accumulated grounding process between the speakers. We expressed the discourse as a hierarchical grounding network by extending the states of network so as to involve the level of grounding, and arranging a discourse unit as a contribution topic so as to formulate what the speakers want to ground. If the lower network is grounded, then the state of upper network transit to the next state, and if the top of network is grounded, the whole discourse is grounded and achieved. We applied this framework to 97 guide-tourist dialogues. We extracted 18 kinds of contribution topics and they were expressed as complicated grounding networks. We also tried to apply this framework to the discussion data.
