Interactive question answering and constraint relaxation in spoken dialogue systems
Natural Language Engineering, 2009•cambridge.org
We explore the relationship between question answering and constraint relaxation in
spoken dialogue systems and develop dialogue strategies for selecting and presenting
information succinctly. In particular, we describe methods for dealing with the results of
database queries in information-seeking dialogues. Our goal is to structure the dialogue in
such a way that the user is neither overwhelmed with information nor left uncertain as to how
to refine the query further. We present two sets of evaluation results for a restaurant selection …

In particular, we describe methods for dealing with the results of database queries in information-seeking dialogues. Our goal is to structure the dialogue in such a way that the user is neither overwhelmed with information nor left uncertain as to how to refine the query further. We present two sets of evaluation results for a restaurant selection task: one is a system performance evaluation experiment involving twenty subjects, the other is an experimental evaluation of the use of suggestions involving sixteen subjects.
