TAILIEUCHUNG - Báo cáo khoa học: "Compositional Semantics for Linguistic Formalisms"

In what sense is a grammar the union of its rules? This paper adapts the notion of composition, well developed in the context of programming languages, to the domain of linguistic formalisms. We s t u d y alternative definitions for the semantics of such formalisms, suggesting a denotational semantics that we show to be compositional and fully-abstract. This facilitates a clear, mathematically sound way for defining g r a m m a r modularity. | Compositional Semantics for Linguistic Formalisms Shuly Wintner Institute for Research in Cognitive Science University of Pennsylvania 3401 Walnut St. Suite 400A Philadelphia PA 19018 Abstract In what sense is a grammar the union of its rules This paper adapts the notion of composition well developed in the context of programming languages to the domain of linguistic formalisms. We study alternative definitions for the semantics of such formalisms suggesting a denotational semantics that we show to be compositional and fully-abstract. This facilitates a clear mathematically sound way for defining grammar modularity. 1 Introduction Developing large scale grammars for natural languages is a complicated task and the problems grammar engineers face when designing broad-coverage grammars are reminiscent of those tackled by software engineering Erbach and Uszkoreit 1990 . Viewing contemporary linguistic formalisms as very high level declarative programming languages a grammar for a natural language can be viewed as a program. It is therefore possible to adapt methods and techniques of software engineering to the domain of natural language formalisms. We believe that any advances in grammar engineering must be preceded by a more theoretical work concentrating on the semantics of grammars. This view reflects the situation in logic programming where developments in alternative definitions for predicate logic semantics led to implementations of various program composition operators Bugliesi et al. 1994 . This paper suggests a denotational semantics for unification-based linguistic formalisms and shows that it is compositional and fully- 1 am grateful to Nissim Francez for commenting on an earlier version of this paper.

While most of the results we report on are probably not surprising .
