Abstract
In diesem Artikel, der im Anwendungsbereich der Patentrecherche und Patentinformation angesiedelt ist, wird das automatische Gruppieren von Patentdokumenten - das so genannte Clustering - als ein Werkzeug zur Aufbereitung der Ergebnismenge einer Datenbankanfrage untersucht. Der Schwerpunkt liegt dabei auf der Evaluierung von drei Clustering-Verfahren mittels Nutzerbewertungen.
