This paper proposes a method to model confirmations for example-based dialog management. To enable the system to provide a confirmation to the user in an appropriate time, we employed a multiple dialog state representation approach for keeping track of user input uncertainty and implemented a confirmation agent which decides when the information gathered from the user contains an error. We developed a car navigation dialog system to evaluate our proposed method. Evaluations with simulated dialogs show our approach is useful for handling misunderstanding errors in example-based dialog management.
