Recto/Verso. Un système de conversion automatique ancienne/nouvelle orthographe à visée linguistique et didactique

This paper presents Recto / Verso, a natural language processing system dedi- cated to the application of the 1990 French spelling rectifications. This system was developed for supporting the awareness-raising campaign promoted last March by the Superior council of the French language in Belgium. We first remind the motivations and the content of the reform, and we draw up the didactic principles followed during the campaign. The most important part of this paper is then focused on the system's implementation. We finally end by a short analysis of the campaign's impact on the users. Mots-cles : Rectifications orthographiques de 1990, conversion ancienne / nouvelle or- thographe, objectifs didactiques, machines a etats finis.
