Title (EN) DETERMINING CORE GEOGRAPHICAL INFORMATION IN A DOCUMENT
(FR) DÉTERMINATION D’INFORMATIONS GÉOGRAPHIQUES PRINCIPALES DANS UN DOCUMENT
Abstract: front page image
(EN)A method determines core geographical information in a document by computing a score for each geographical name found in the document. The computation of the score uses the appearance frequency of the respective geographical name and positional weights assigned to various types of appearance positions of the geographical name in the document. The system determines the core geographical information in the document based on the scores of the geographical names found in the document. The method may further compute aggregated scores of geographical regions related to the geographical names and determine the core geographical information using both the aggregated scores of geographical regions and the scores of individual geographical names to increase accuracy.
(FR)Un procédé permet de déterminer des informations géographiques principales dans un document en calculant un score pour chaque nom géographique trouvé dans le document. Le calcul du score utilise la fréquence d’apparition du nom géographique respectif et des poids de position assignés à divers types de positions d’apparition du nom géographique dans le document. Le système détermine les informations géographiques principales dans le document sur la base des scores des noms géographiques trouvés dans le document. Le procédé peut en outre calculer des scores agrégés de régions géographiques se rapportant aux noms géographiques et déterminer les informations géographiques principales en utilisant à la fois les scores agrégés de régions géographiques et les scores de noms géographiques individuels pour augmenter la précision.
