Underspecified Representation and Resolution of
Ellipsis

This thesis deals with the underspecified semantic
representation and resolution of ellipsis. We focus
on the interaction of Verb Phrase Ellipsis
(henceforth VPE) and anaphora. In particular, we
address the distribution of strict and sloppy
readings in these phenomena and present an analysis
to explain it. This analysis is integrated into a
framework that concerns a uniform treatment of
semantically underspecified information and
parallelism phenomena in discourse. The analysis
put forward in this thesis gives correct
predictions about the strict and sloppy readings of
a series of problematic cases in the literature. It
does not suffer from undergeneration or
overgeneration problems. We use linking relations
between anaphoric pronouns and their antecedents
and claim that the interaction between linking
relations and the parallelism requirement in VPE
results in strict and sloppy readings. The basic
idea underlying the analysis presented in this
thesis agrees with the proposal made by (Kehler 93;
Kehler 95). Although recently a lot of approaches
to semantic underspecification as well as ellipsis
resolution have emerged in computational
linguistics, few of them are designed to treat both
problems uniformly. The framework proposed in this
thesis shows how to integrate the treatment of
ellipsis resolution with semantic
underspecification in a uniform and elegant way.
