On Underspecification
Author: Pinkal, Manfred
Editor:
Underspecification has become fashionable in computational
semantics. In this chapter, I will try to give an
idea of what semantic underspecification is, what
it has been good for, and what the perspective for
future application are. I will start with the
inspection of specific phenomena and techniques
which are usually associated with the notion of
underspecification (in Section 1 and 2,
respectively). In Sect. 3, I will try to indicate
the main motivations for using underspecification
techniques. Then, I will point out one important
use of the concept in some detail, i.e., direct
reasoning with incomplete semantic information,
discussing first the appropriate truth-conditional
basis (Sect. 4), and second perspectives on
efficient reasonig systems (Sect. 5). I will
conclude with some remarks about the general status
of the semantic underspecification concept, in
Sect. 6.
