Changement climatique et toponymie. Étude de la répartition ancienne du hêtre à travers ses traces toponymiques

In this paper we evaluate the feasibility of estimating the previous distribution of a tree species, the beech, from the analysis of toponyms presently in use and referring to this species. Specialists from toponymy, agromomy and geometics have been involved. Toponyms are a precious source of information about past distribution: more than 6100 toponyms referring to beech have been detected. MOT...

Then, we present Dung’s argumentation formal framework and introduce the expansive, narrowing and monotonic change notions. These noti...

Révision de systèmes d’argumentation : changement minimal du statut des arguments

In this paper, we investigate the revision issue for argumentation systems à la Dung. We focus on revision as minimal change of the arguments status. Contrarily to most of the previous works on the topic, the addition of new arguments is not allowed in the revision process, so that the revised system has to be obtained by modifying the attack relation, only. We introduce a language of revision ...
