Abstract

In der elektronischen Kommunikationsumgebung von Bibliotheken existiert eine Vielfalt von Informationsressourcen in jeglicher Form, die hochaktuell und dank Discoverysystemen größtenteils inhaltlich vollständig durchsuchbar sind. Vor diesem informationstechnischen Hintergrund zeigt sich die erstaunliche Stärke von tradierten Erschließungsinstrumenten. Allerdings endet der Mehrwert dieser sacherschließenden Metadaten dort, wo bibliothekarische Daten aufhören. Die intellektuell basierte Verschlagwortung kann aufgrund der stetig anwachsenden Datenmenge aus unterschiedlichen Informationsräumen nicht mehr bewältigt werden. Für den Einsatz eines kontrollierten Vokabulars, welches semantische Kontextinformationen transportieren kann und automatisierte Verfahren dank entsprechender Datenmodellierung unterstützt, ist ein Thesaurus das Mittel der Wahl. Der Artikel gibt einen Überblick über den Mehrwert von Thesauri in Discoverysystemen, beschreibt den Vorgang der Thesauruserstellung mit dem Schwerpunkt der Auswahl von Vokabularmanagementsystemen im Linked-Data-Kontext und stellt die verschiedenen Ansätze der Integration eines Thesaurus in das vor Ort verwendete Discoverysystem WILBERT vor.
