Une notation semantique et ses implications linguistiques

Une notation s~mantique et ses implications linguistiques (R6sum6) i. Une notation estpropos~e en vue de fixer la structure s~mantique d'un texte naturel de fagon a en permettre le traitement automatique ult~rieur, logique (d~duction) ou linguistique (traduction). A la difference d'un langage documentaire (ou d'information), la notation propos~e ne vise, en premier lieu qu'~ ~claircir et ordonn...

Thèse de doctorat Discipline : Mathématiques et leurs interactions

This manuscript is dedicated to the study of infinite dimensional sub-Riemannian geometry and its applications to shape analysis using diffeomorphic deformations. The first part is a detailed summary of our work, while the second part combines the articles we wrote during the last three years. In the first two chapters, we extend the framework of subRiemannian geometry to infinite dimensions, e...

La dose tolérée et toxique de la saponine chez les chèvres et les moutons

Mathématiques Appliquées

We consider a network shared by non-cooperative two types of users, group users and individualusers, each user of the first type has a significant impacton the load of the network, whereas a user of the sec-ond type doesn’t. Both group users as well as individualusers choose their routes so as to minimize their costs.We further consider the case that the users may have<l...

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...
