Abstract

L'invention concerne un système et un procédé d'évaluation de la pertinence d'un document de référence et comprend : un module de comparaison de mots sujets, destiné à comparer au moins un mot sujet attribué à un document d'entrée avec au moins un mot sujet attribué à un document de référence dans un procédé de mise en correspondance ; et un module d'évaluation de corrélation destiné à évaluer la corrélation entre le document d'entrée et le document de référence au moyen du résultat de la comparaison du module de comparaison de mots sujets. Selon l'invention, un document de référence peut être analysé pour examiner la corrélation entre le document d'entrée et le document de référence, ce qui permet de déterminer qu'un document de référence pertinent est cité, et de déterminer également des objets, des documents universitaires notamment, devant être soumis à une inspection visant à déceler un plagiat.
