Abstract

L'invention concerne un procédé de création d'un ensemble de données de référence (109) pour un document, le document présentant un premier ensemble de caractéristiques et un deuxième ensemble de caractéristiques, le premier ensemble de caractéristiques pouvant être saisi au moyen d'un premier procédé de saisie, le deuxième ensemble de caractéristiques pouvant être saisi au moyen d'un deuxième procédé de saisie. Le procédé comporte les caractéristiques suivantes : saisie (101) du premier ensemble de caractéristiques par le premier procédé de saisie afin d'obtenir un premier ensemble de caractéristiques de référence (102), saisie (103) du deuxième ensemble de caractéristiques par le deuxième procédé de saisie pour obtenir un deuxième ensemble de caractéristiques de référence (104), association (105) du premier ensemble de caractéristiques (102) à une information latérale indiquant une propriété du premier procédé de saisie, afin d'obtenir un premier ensemble de données caractéristique de référence (106) de l'ensemble de données de référence du document (109), et association (113) du deuxième ensemble de caractéristiques de référence (104) à une autre information latérale indiquant une propriété du deuxième procédé de saisie, afin d'obtenir un deuxième ensemble de données caractéristique (108) de l'ensemble de données de référence du document (109).
