Abstract

Ce procédé comprend la fourniture (100) de groupes de symptômes, la génération (140) d'une matrice de cooccurrence associant à chaque couple de premier et deuxième symptômes un score de cooccurrence représentatif d'une corrélation entre la présence du premier et du deuxième symptômes dans un même groupe, la détermination (150) de signatures potentielles, comprenant l'identification, pour chaque symptôme, de symptômes corrélés tels que le score de cooccurrence entre ledit symptôme et chaque symptôme corrélé soit supérieur à un seuil, chaque signature potentielle étant constituée d'un symptôme et des symptômes corrélés audit symptôme, et classification (166) de chaque signature potentielle en signature univoque si un nombre de groupes comprenant tous les symptômes de la signature potentielle est supérieur à un nombre seuil prédéterminé, ou en signature plurielle si ledit nombre est inférieur au nombre seuil.
