A Uniform Approach to Underspecification and Parallelism
Autor: Niehren, Joachim and Pinkal, Manfred and Ruhrberg, PeterHerausgeber:
We propose a unified framework in which to
treat semantic underspecification and
parallelism phenomena in discourse. The
framework employs a constraint language
that can express equality and subtree
relations between finite trees. In addition,
our constraint language can express the
equality up-to relation over trees which
captures parallelism between them. The
constraints are solved by context
unification. We demonstrate the use of
our framework at the examples of quantifier
scope, ellipses, and their interaction.
