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