Applicative and Combinatory Categorial Grammar is an extension of Steedman's Combinatory Categorial Grammar by a canonical association between rules and Curry's combinators on one hand and metarules which control type-raising operations on the other hand. This model is included in the general framework of Applicative and Cognitive Grammar (Desclés) with three levels of representation : (i) phenotype (concatened expressions) ; (ii) genotype (applicative expressions) ; (iii) the cognitive representations (meaning of linguistic predicates). The aim of the paper is : (i) an automatic parsing of phenotype expressions that are underlying to sentences ; (ii) the building of applicative expressions. The theoretical analysis is applied to spurious ambiguity and coordination.
