A Uniform Approach to Underspeci cation and Parallelism
نویسندگان
چکیده
We propose a uniied framework in which to treat semantic underspeciication and parallelism phenomena in discourse. The framework employs a constraint language that can express equality and subtree relations between nite 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 uniication. We demonstrate the use of our framework at the examples of quantiier scope, ellipsis, and their interaction.

Fachbereich 8.7 Computerlinguistik Universitt at Des Saarlandes Semantic Underspeciication and Ellipsis Resolution
This thesis deals with the underspeci ed 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 enables a uniform treatment of semantica...
متن کاملDialogue strategies guiding users to their communicative goals
Much work has been done in dialogue modeling for Human Computer Interaction. Problems arise in situations where disambiguation of highly ambiguous data base output is necessary. We propose to model the task rather than the dialogue itself. Furthermore, we propose underspeci ed representations to represent relevant data and to serve as a base for generating clari cation questions that guide the ...

The interface speci cation of a procedure describes the procedure s behavior using pre and postconditions These pre and postconditions are written using various functions If some of these functions are partial or underspeci ed then the procedure speci cation may not be well de ned We show how to write pre and postcondition speci cations that avoid such problems by having the precondition protec...

متن کاملA General Reasoning Scheme for Underspeci ed Representations
In this paper we present an underspeci ed logic, i.e. a pair consisting of a proper underspeci ed semantic representation formalism and a deductive component that directly operates on these structures. We show how the main features of this formalism can be imported into other existing underspeci ed semantic representation formalisms. We also show that deduction rules may be imported there along...
