Abstract

La présente invention concerne un dispositif de récupération d'informations destiné à récupérer les informations d'une page Web sur Internet, sur la base des informations de récupération saisies depuis un terminal client et à transmettre le résultat de récupération au terminal client. La valeur pondérée de la page Web est calculée en utilisant les informations enregistrées relatives à la page Web, lorsqu'il apparaît dans un premier résultat de récupération que la page Web relative à un mot-clé a été récupérée à partir des informations de récupération. L'ordre de la page Web contenue dans le premier résultat de récupération est déterminé sur la base de la valeur pondérée calculée, afin de créer un second résultat de récupération. Ce second résultat est transmis au terminal client.
