Abstract

Une méthode mise en application par ordinateur, un pipeline traitement et un système créent une carte sémantique hiérarchique dun document et dinformation extraite. La méthode comprend une répartition du document dans des sections majeures par accès au document, par reconnaissance dune structure hiérarchique du document, par division du document dans les sections majeures à laide dun profileur de données et dun module dapprentissage automatique, par classification des sections majeures, par mappage des sections majeures à des éléments principaux dans lun des multiples niveaux, par recherche de lune des sections majeures, par identification des sous-sections à partir de la section majeure pour atteindre un score de fiabilité maximal indiquant que les sous-sections sassocient à lélément principal, par extraction de linformation à partir des sous-sections identifiées à laide de modélisateurs de séquences et de caractéristiques linguistiques fournies par le profileur de données, par génération de la carte sémantique hiérarchique du document à laide de linformation extraite, et par affichage, dans une interface utilisateur, de sélections descendantes des éléments principaux.
