Layering in structural-functional grammars

Layering in structural-functional grammars

This article presents an overview of the notion of layering in three types of structuralfunctional grammars. Layering is interpreted in a broad sense to refer to two types of linguistic differentiations: (1) on the one hand, a distinction between levels of coding, namely, syntax/grammar, semantics, pragmatics; (2) on the other hand, a differentiation between speaker-related vs. content-related ...

Types in Functional Unification Grammars

In this paper, we present several extensions to the FU formalism that address these limitations. These extensions are based on the formal semantics Functional Unification Grammars (FUGs) are presented in (Elhadad, 1990). They have been impopular for natural language applications because the plemented and tested on several applications. formalism uses very few primitives and is uniform and expre...

Introduction to Functional Grammars

— Formal grammars are extensively used in Computer Science and related fields to study the rules which govern production of a language. The use of these grammars can be extended beyond mere language production. One possibility is to view these grammars as logical machines, similar to automata, which can be modified to compute or help in computation, while also performing the basic task of langu...

Attribute grammars in the functional style

For long, attribute grammars have formed an isolated programming formalism. We show how we may embed the attribute grammar approach in a modern functional programming language. The advantages of both sides reinforce each other: the former provides compositionality and the latter naming abstraction and higher-orderness. Through a sequence of program transformations we show different aspects of t...
