摘要：To tackle the problem of presenting a
large number of options in spoken dialogue
systems, we identify compelling options
based on a model of user preferences,
and present tradeoffs between alternative
options explicitly. Multiple attractive options
are structured such that the user can
gradually refine her request to find the
optimal tradeoff. We show that our approach
presents complex tradeoffs understandably,
increases overall user satisfaction,
and significantly improves the user’s
overview of the available options. Moreover,
our results suggest that presenting
users with a brief summary of the irrelevant
options increases users’ confidence in
having heard about all relevant options.
