Acquisition de schémas prédicatifs verbaux en japonais

Abstract : Lexical knowledge acquisition of verbal constructions is an important issue for natural language processing as well as lexicography, which aims at referencing emerging linguistic usages. Such a task implies numerous challenges, technical as well as theoretical. In this thesis, we had a closer look at two fundamental aspects of the description of the verb: the notion of lexical item and the distinction between arguments and adjuncts. Following up on studies in natural language processing and linguistics, we embrace the hypothesis that there is no clear distinction between homonyms and quasi-synonyms, and the hypothesis of a continuum between arguments and adjuncts. We provide a complete approach to lexical knowledge acquisition of verbal constructions from an untagged news corpus. The acquisition process makes use of the notion of argumenthood, and builds models of the two continuums. Our lexicon has been evaluated on a qualitative and comparative basis. Siding with lexicography anchored in the theoretical framework of corpus linguistics, we show the difficulty of using lexical resources to describe as yet unseen data.
