Categorial Grammars with Negative Information
Wojciech Buszkowski · 1996
this paper we discuss some possibilities of introducing negative information in the formalism of categorial grammar. Traditionally, formal grammars, including categorial grammars, admit positive information only. For instance, one postulates the rule S)NP,VP but not \\GammaS)NP,\\GammaVP; here \\GammaA stands for the negation (complement) of category A.
