Abstract : This thesis focuses on the syntactic and semantic analysis of sentences, when using, for the syntactic analysis, a polarized lexicalized grammatical formalism and taking interaction grammars as an example. In lexicalized grammatical formalisms, polarities enable to explicitly control the composition of syntactic structures. First we use the need for composition expressed by some polarities to define a weak notion of grammar reduction that is applicable to any polarized lexicalized grammar. Then, we study the first step of the syntactic analysis in lexicalized formalisms: supertagging. We use once again the need for composition expressed by some polarities to design three symbolic methods for filtering supertaggings that we implement on automata. Finally, we look at the syntax-semantics interface of lexicalized formalisms. We show how the use of graph rewriting as the model of computation concretely enables to use rich syntactic structures to compute underspecified semantic representations.
