TAILIEUCHUNG - Báo cáo khoa học: "Coupling CCG and Hybrid Logic Dependency Semantics"

Categorial grammar has traditionally used the λ-calculus to represent meaning. We present an alternative, dependency-based perspective on linguistic meaning and situate it in the computational setting. This perspective is formalized in terms of hybrid logic and has a rich yet perspicuous propositional ontology that enables a wide variety of semantic phenomena to be represented in a single meaning formalism. Finally, we show how we can couple this formalization to Combinatory Categorial Grammar to produce interpretations compositionally | Proceedings of the 40th Annual Meeting of the Association for Computational Linguistics ACL Philadelphia July 2002 pp. 319-326.

We present an alternative dependency-based perspective on linguistic meaning and situate it in the computational setting. This perspective is formalized in terms of hybrid logic and has a rich yet perspicuous propositional ontology that enables a wide variety of semantic phenomena to be represented in a single meaning formalism. Finally we show how we can couple this formalization to Combinatory Categorial Grammar to produce interpretations compositionally. 1 Introduction The A-calculus has enjoyed many years as the standard semantic encoding for categorial grammars and other grammatical frameworks but recent work has highlighted its inadequacies for both linguistic and computational concerns of representing natural language semantics Copestake et al. 1999 Kruijff 2001 . The latter couples a resource-sensitive categorial proof theory Moortgat 1997 to hybrid logic Blackburn 2000 to formalize a dependency-based perspective on meaning which we call here Hybrid Logic Dependency Semantics HLDS . In this paper we situate HLDS in the computational context by explicating its properties as a framework for computational semantics and linking it to Combinatory Categorial Grammar CCG . The structure of the paper is as follows. In 2 we briefly introduce CCG and how it links syntax and semantics and then discuss semantic representations that use indexes to identify subparts of logical forms. 3 introduces HLDS and evaluates it
