Ce procédé consiste à chercher, dans ledit ensemble de documents, les documents de base qui contiennent ledit terme de recherche et à analyser les documents de base trouvés pour déterminer si le terme de recherche contenu dans lesdits documents de base trouvés, respectivement, a un sens donné. Cette analyse consiste à générer un document-texte pour représenter les éléments entourant le terme de recherche et leur position absolue ou relative correspondante par rapport audit terme de recherche, les éléments dudit document-texte codant lesdites positions absolues ou relatives desdits éléments entourant le terme de recherche à l'aide de chaînes de textes correspondantes ; à entrer ledit document-texte dans un dispositif de classement formé pour déterminer si un document-texte entré appartient ou non à une certaine catégorie de classement, la formation ayant été faite sur la base d'un échantillon de formation de documents-textes générés pour des documents dans lesquels le terme entouré par lesdits éléments revêt le sens entré par ledit utilisateur ; et à classer le document-texte entré pour déterminer si ledit terme de recherche revêt le sens entré.
