چکیده
This paper proposes a new framework for a spoken dialogue system based on dialogue examples between human subjects and the Wizard of OZ (WOZ) system. Using this framework and a model of information retrieval dialogue, a spoken dialogue system for retrieving shop information while driving in a car has been designed. The system refers to the dialogue examples to find an example that is suitable for generating a query or a reply. The authors have also constructed a large-scale dialogue database using a WOZ system, which enables efficient collection of dialogue examples.
