Ambiguity, Underspecification and Discourse Interpretation
نویسنده
چکیده
A formal analysis of ambiguity processing is a necessary prerequisite for the development of a theory of underspecification and discourse interpretation for NLP systems. The analysis presented here is based on a distinction between semantic ambiguity and perceived ambiguity. A sentence is semantically ambiguous if it has a multiplicity of interpretations; a form of underspecified representation is introduced that can be used as the translation of a sentence that is semantically ambiguous in this sense. Perceived ambiguity, on the other hand, is captured in terms of hypothesis generation in context.

A Uniform Approach to Underspecification and Parallelism
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...
متن کاملAnaphora resolution and reambiguation∗
Starting off from common assumptions on the relationship between ambiguity and the process of disambiguation with regard to the technique of underspecification, we argue that disambiugation may be viewed as non-monotonic in nature in certain cases involving anaphora resolution. We then go on to present a formal analysis framed in a coupling of Discourse Representation Theory and Constraint Logi...

متن کاملUsing the Situational Context to Resolve Frame of Reference Ambiguity in Route Descriptions
The application domain for this research is human-robot interaction, specifically the interpretation of route instructions by robots. Two features of spatial language that are of particular relevance to route instruction interpretation are the notions of perspective and spatial reference frame. This paper presents a computational model that addresses the problem of resolving frame of reference ...
متن کاملRobust Text Analysis via Underspecification
This paper is concerned with the robust analysis of the discourse structure of a text via underspecification. Most current discourse theories (e.g. Rhetorical Structure Theory (RST) by Mann and Thompson (1988), Abduction by Hobbs et al. (1993) or Segmented Discourse Representation Theory (SDRT) by Asher (1993)) require detailed world and context knowledge for the derivation of the discourse str...
