This paper reports on a user-centred evaluation of search process characteristics within a thesaurus-enhanced search environment and the ways in which these characteristics affect users’ judgment of search terms and results. The study has addressed the questions relating to the types of search moves and the relationship between search moves and search terms and results. Résumé : Cet article pré...
RÉSUMÉ. L’article s’intéresse à la formalisation, dans une optique de calcul, des définitions lexicographiques BDéf (Altman et Polguère, 2003). La richesse informationnelle de ces définitions laisse envisager de nombreux calculs utiles aussi bien à la pratique lexicographique qu’à une réflexion plus générale sur la modélisation du sens lexical. De tels calculs ne peuvent toutefois être mis en œ...

Résumé: Dans cet article nous évaluons diverses approches pour filtrer le contenu « procédural » d’un document, et mesurons leur impact sur la classification d’une collection d’appels d’offres. Deux types d’approches sont testées : la sélection de termes à partir d’un vocabulaire de référence, constitué à partir des descriptions du schéma de classification, et le filtrage de phrases. Nous ne tr...
In this paper we prove a large deviations principle for the invariant measures of a class of reaction–diffusion systems in bounded domains of Rd , d 1, perturbed by a noise of multiplicative type. We consider reaction terms which are not Lipschitzcontinuous and diffusion coefficients in front of the noise which are not bounded and may be degenerate. This covers for example the case of Ginzburg–...
there has been a gradual shift of focus from the study of rule systems, which have increasingly been regarded as impoverished, … to the study of systems of principles, which appear to occupy a much more central position in determining the character and variety of possible human languages. there is a set of absolute universals, notions and principles existing in ug which do not vary from one ...
