Abstract : In the context of lexicalized grammars, we propose general methods for lexical disambiguation based on polarization and abstraction of grammatical formalisms. Polarization makes their resource sensitivity explicit and abstraction aims at keeping essentially the mechanism of neutralization between polarities. If a grammar in the initial formalism happens to be lexicalized, parsing with the simplified grammar in the abstract formalism can be used efficiently for filtering lexical selections.
