Méthodes et modèles de construction automatisée d'ontologies pour des domaines spécialisés

Abstract : The thesis has been prepared within a co-supervision agreement with the Professors Jean-Hugues Chauchat (ERIC-Lyon2) and N.V. Charonova (National Polytechnic University of Kharkov in Ukraine).The results obtained can be summarized as follows:1.State of the art:Retrospective of theoretical foundations concerning the formalization of knowledge and natural language as precursors of ontology engineering.Update of the state of the art on general approaches in the field of ontology learning, and on methods for extracting terms and semantic relations.Overview of platforms and tools for ontology construction and learning; list of lexical resources available online able to support ontology learning (concept learning and relationship).2.Methodological proposals:Learning morphosyntactic patterns and implementing partial taxonomies of terms.Finding semantic classes representing concepts and relationships for the field of radiological safety.Building a frame for the various stages of the work leading to the construction of the ontology in the field of radiological safety.3.Implementation and experiments:Loading of two corpuses specialized in radiological protection, in French and Russian, with 1,500,000 and 600,000 lexical units respectively.Implementation of the three previous methods and analysis of the results obtained.The results have been published in 13 national and international journals and proceedings, between 2010 and 2016, including IMS-2012, TIA-2013, TOTH-2014, Bionica Intellecta (Бионика интеллекта) , Herald of the NTU "~ KhPI ~" (Вестник НТУ "~ ХПИ ~").
