Phrase structure grammars for the expression of vague voncepts in Spanish

Abstract

This paper characterizes grammars generating Spanish sentences of imprecise meaning. The basic grammar generating sentences onforming to the standard paradigm of fuzzy logic (Quantifier + Noun + Verb + Modifier + Adjective) is systematically deformed (by inversion, suppression or addition of nonterminal elements in its production rules) to produce a series of grammars generating grammatical, semantically acceptable semigrammatical or ungrammatical sentences.
