Evaluation of content presentation strategies for an in-car spoken dialogue system

چکیده
In this paper we present a framework for managing information presentation in spoken dialogue systems. We describe a content optimization module that makes use of ontological relationships in information-seeking dialogues in order to organize knowledge base items and perform adjustments such as relaxing or tightening user constraints. We present the results of an experimental evaluation comparing two response strategies: (a) one that uses the content optimization module to offer suggestions and (b) one that gives no suggestions. The results indicate that giving such suggestions is preferred when a user query matches either no items or many items in the knowledge base, and may also lead to more efficient dialogues.

Recent work on evaluation of spoken dialogue systems suggests that the information presentation phase of complex dialogues is often the primary contributor to dialogue duration. This indicates that better algorithms are needed for the presentation of complex information in speech. Currently however we lack data about the tasks and dialogue strategies on which to base such algorithms. In this pa...
