| Research Abstract |
We proposed a new dialog strategy which can recover from system's misunderstandings without confirmation system utterances. In this strategy, system uses a graph search algorithm, in which each node represent an understanding state. To make a response to the user, system adopts 'efficiency measure' which enables the system efficient search and 'consistency measure' which prevents unnatural response inconsistent with the dialog history. We developed a system with these methods and evaluated it. It is proved that the system was more efficient and obtained more user satisfaction than conventional ones.
