CA 2448982

The invention relates to a method for large syntactical analysis based on unsupervised learning on a corpus comprising an iterative sequencing of two phases: a learning phase wherein linguistic information is acquired using unambiguous analysis cases, and a resolution phase wherein ambiguous analysis cases are resolved using information acquired during the learning phase. The invention is used in particular for creating specialised terminological resources for an information processing system, for creating an ontology for a specialised information search engine on the web, for a terminological lexicon for an automatic translation system, or for a thesaurus for an automatic indexing system.

Procédé d'analyse syntaxique large basé sur un apprentissage non supervisé sur un corpus, comprenant un enchaînement itératif de deux phases: une phase d'apprentissage, dans laquelle des informations linguistiques sont acquises à partir des cas d'analyse non ambigus; une phase de résolution, dans laquelle les cas d'analyse ambigus sont résolus en exploitant les informations acquises lors de la phase d'apprentissage. Application notamment pour la construction de ressources terminologiques spécialisées pour un système de traitement de l'information, d'une ontologie pour un moteur de recherche d'informations spécialisées sur le Web, d'un lexique teminologique pour un système de traduction automatique, ou d'un thesaurus pour un système d'indexation automatique.
