Abstract

La présente invention concerne un système de regroupement et de recherche d’événements d’actualité configuré pour créer dans un premier temps un ensemble de données candidates de documents, dans un deuxième temps un ensemble de clusters initiaux basés sur la proximité ou le statut de similitude des doublons, et dans un troisième temps un cluster agrégé en fusionnant les clusters initiaux avec les documents sources. L’invention génère des clusters de niveau supérieur pour les événements d’actualité sur la base d’une étiquette thématique ou d’un composant « source » fourni par la rédaction, et génère des clusters axés sur des sous-thèmes à l’aide d’un algorithme. Le système utilise un algorithme de regroupement agglomératif pour rassembler et structurer les documents en ensembles de résultats distincts. Les décisions concernant la fusion de documents ou de clusters connexes sont prises en fonction de la similitude des preuves provenant de deux sources distinctes, l’une s’appuyant sur une signature numérique basée sur le texte non structuré du document, l’autre basée sur la présence de balises d’entités nommées qui ont été attribuées au document par un étiqueteur d’événements ou d’entités nommées tel que le moteur/service Web Thomson Reuters Calais.
