Resolving Fragments Using Discourse Information
This paper describes an extension of
RUDI, a dialogue system component for
Resolving Underspecification with
Discourse Information'
(Schlangen et al., 2001). The extension handles
the resolution of the intended meaning of
non-sentential utterances that denote propositions or questions.
Some researchers have observed that there are complex syntactic,
semantic and pragmatic constraints on the acceptability of such
fragments, and have used this to motivate an unmodular architecture
for their analysis. In contrast, our implementation is based on a
clear separation of the processes of constructing compositional
semantics of fragments from those for resolving their meaning in
context. This is shown to
have certain theoretical and practical advantages.
