MICRO is a multi-agents speech understanding system largely inspired by cognitive models. Our aim with this cognitive approach is to improve the adaptative abilities of the system. This paper mainly focuses on the modelization of the linguistic level. It describes the cooperation between, on the one hand, a syntactic parser using a Lexical Functional Grammar, and on the other hand, a semantic analyser that performs priming according the paradigm of differential compositionnal semantics.
Keywords: speech understanding, cognitive modelization, multi-agents system, syntax-semantics cooperation, LFG grammar, compositionnal semantics
