Analyses linguistiques et techniques d'alignement pour créer et enrichir une ontologie topographique

One of the goals of the GéOnto project is to build an ontology of topographic concepts. This ontology results from the enrichment of a first taxonomy developed beforehand, through the analysis of two types of textual documents: technical database specifications and description of journeys. This work relies on natural language processing and ontology alignment techniques, as well as external kno...

Indexation de co-occurrences guidée par la structure des documents et contrôlée par une ontologie et l'exploitation du corpus

This paper addresses the problem of indexing very large enterprise corpuses. We have designed a simple yet efficient (especially in terms of computation time and the size of the generated results) method allowing to filter, on a per-document basis, the most representative co-occurrences of the documents. The reason for using co-occurrences is twofold. First, queries composed by experts on speci...

Construction d'une ontologie par transformation de systèmes d'organisation des connaissances et évaluation de la confiance

This paper presents an original method of knowledge base (ontology) creation from transformations of several sources of knowledge. These sources are derived from the knowledge organization systems (thesauri, taxonomies, etc.). The sources are weighted by a confidence score. The method is based on a module aggregating ontological design patterns. We have implemented this method in an agronomical...
