abstract: An attractive way to model
the relation between an underspecified syntactic representation and
its completions is to let the underspecified representation correspond
to a  logical description and the completions to the
models of that description. This approach, which underlies the
Description Theory of (Marcus et al. 1983)  has been integrated
in (Vijay-Shanker 1992) with a pure unification approach to 
Lexicalized Tree-Adjoining
Grammars  (Joshi et al.\ 1975, Schabes 1990). We generalize 
Description Theory by integrating semantic
information, that is, we propose to tackle both syntactic and
semantic underspecification using descriptions.
