Abstract

L'invention concerne un procédé et un dispositif permettant de déterminer si une page Web comprend des données de point d'intérêt (POI). Le procédé consiste à : acquérir plusieurs éléments de données POI à partir d'Internet (S101) ; parcourir plusieurs pages Web comprenant des informations d'adresse (S102) ; normaliser séparément les informations d'adresse dans les multiples éléments de données POI et les informations d'adresse incluses dans les multiples pages Web en informations de longitude et de latitude (S103) ; apparier les informations de longitude et de latitude des multiples éléments de données POI avec celles des multiples pages Web (S104) ; pour les données POI et les pages Web ayant les mêmes informations de longitude et de latitude, effectuer une recherche dans les pages Web en fonction des noms POI correspondant aux données POI de façon à déterminer si les pages Web comprennent les noms POI des données POI (S105) ; et lorsque les pages Web comprennent les noms POI des données POI, déterminer que les pages Web comprennent les données (S106) du point d'intérêt (POI). Le procédé et le dispositif aident à déterminer ensuite la précision des données POI collectées en fonction de la précision du contenu enregistré par les pages Web, ce qui permet de garantir ensuite de manière fiable la collecte de données POI précises sur Internet à grande échelle.
