Abstract
Im Fraunhofer-Informationszentrum Raum und Bau (IRB) wird Fachliteratur im Bereich Planen und Bauen bibliographisch erschlossen. Die daraus resultierenden Dokumente (Metadaten-Einträge) werden u.a. bei der Produktion der bibliographischen Datenbanken des IRB verwendet. In Abb. 1 ist ein Dokument dargestellt, das einen Zeitschriftenartikel beschreibt. Die Dokumente werden mit Deskriptoren von einer Nomenklatur (Schlagwortliste IRB) indexiert. Ein Deskriptor ist "eine Benennung., die für sich allein verwendbar, eindeutig zur Inhaltskennzeichnung geeignet und im betreffenden Dokumentationssystem zugelassen ist". Momentan wird die Indexierung intellektuell von menschlichen Experten durchgeführt. Die intellektuelle Indexierung ist zeitaufwendig und teuer. Eine Lösung des Problems besteht in der automatischen Indexierung, bei der die Zuordnung von Deskriptoren durch ein Computerprogramm erfolgt. Solche Computerprogramme werden im Folgenden auch als Klassifikatoren bezeichnet. In diesem Beitrag geht es um ein System zur automatischen Indexierung von deutschsprachigen Dokumenten im Bereich Bauwesen mit Deskriptoren aus der Schlagwortliste IRB.
