Automatische Indexierung auf Basis von Titeln und Autoren-Keywords – ein Werkstattbericht

Abstract

Automatische Verfahren sind für Bibliotheken essentiell, um die Erschliessung stetig wachsender Datenmengen zu stemmen. Die Deutsche Zentralbibliothek für Wirtschaftswissenschaften – Leibniz-Informationszentrum Wirtschaft sammelt seit Längerem Erfahrungen im Bereich automatischer Indexierung und baut hier eigene Kompetenzen auf. Aufgrund rechtlicher Restriktionen werden unter anderem Ansätze untersucht, die ohne Volltextnutzung arbeiten. Dieser Beitrag gibt einen Einblick in ein laufendes Teilprojekt, das unter Verwendung von Titeln und Autoren-Keywords auf eine Nachnormierung der inhaltsbeschreibenden Metadaten auf den Standard-Thesaurus Wirtschaft (STW) abzielt. Wir erläutern den Hintergrund der Arbeit, betrachten die Systemarchitektur und stellen erste vielversprechende Ergebnisse eines dokumentenorientierten Verfahrens vor.Automatic systems are indispensable for libraries in order to make the rapidly growing number of publications accessible to their users. In the past the ZBW – German National Library of Economics – Leibniz Information Centre for Economics has gained practical experience in this field. Due to legal constraints it currently investigates methods that solely use author generated descriptive metadata. This article gives an insight into on-going developments and relates them to past activities. We report on a promising document-oriented approach, which uses author keywords and titles in combination to automatically assign subject headings from the STW Thesaurus for Economics to a document.
