Abstract

La présente invention permet : d'ajouter des méta-informations à une partie spécifiée à l'intérieur d'une page Web ; de transmettre des informations d'attribut prédéterminées aux méta-informations ; d'associer respectivement les méta-informations à l'adresse URL de la page Web et les méta-informations aux informations d'attribut ; et de stocker celles-ci dans une base de données de contenu (201). Une unité de consultation de base de données (208) consulte la base de données de contenu (201) afin d'extraire l'adresse URL d'une page Web à laquelle ont été ajoutées des méta-informations ayant des informations d'attribut correspondant à une clé de recherche souhaitée. Après cela, sur la base de l'adresse URL extraite, une unité de transition de page (211) exécute une transition de la page Web. Ainsi, même si un utilisateur n'est pas explicitement enregistré avec des informations de lien de la base de données destinées à l'origine à effectuer une transition entre des pages Web, il devient possible d'effectuer une transition entre des pages Web par des moyens autres qu'un hyperlien.
