Uwe Reyle (Institute for Computational Linguistics, University of, Stuttgart)
TL;DR
This paper extends underspecified DRS formalism to handle ambiguities from plural NPs, enabling monotonic disambiguation and deductive reasoning across various readings and pronoun resolutions.
Contribution
It introduces a novel extension of underspecified DRSs to represent and reason with ambiguities caused by plural NPs and pronoun references.
Findings
Supports monotonic disambiguation of plural ambiguities
Enables direct deductive reasoning with ambiguous structures
Provides a systematic approach for plural pronoun resolution
Abstract
The paper addresses the problem of representing ambiguities in a way that allows for monotonic disambiguation and for direct deductive computation. The paper focuses on an extension of the formalism of underspecified DRSs to ambiguities introduced by plural NPs. It deals with the collective/distributive distinction, and also with generic and cumulative readings. In addition it provides a systematic account for an underspecified treatment of plural pronoun resolution.
