The utilization of computational linguistic resources in morpho-syntactic disambiguation

Abstract

Syntactic structure of language can be defined by context-free grammars. Contextfree grammars do not facilitate generation of context sensitive aspects, for example, the agreement between different parts of a sentence. This results in a generation of ambiguous sentences. To solve morpho-syntactic disambiguation we have proposed attribute grammars (AG). AG are the extension of context-free grammars, where attributes are associated with grammar symbols, and semantic rules define values of the attributes. An advantage of using the attribute grammar is in solving the ambiguity problem which constitutes a link between syntax and semantics. This link which is achieved with use attributive grammars widens the volume of information that is used for disambiguation.
