Abstract
Die Dewey-Dezimalklassifikation (DDC) wird weltweit für die Erschließung von Bibliotheksbeständen eingesetzt. Um immer auf dem aktuellen wissenschaftlichen Stand zu sein, wird die DDC regelmäßig aktualisiert. Hierdurch kann es zu Begriffsverschiebungen kommen und die Erschließung ähnlicher Titel weicht voneinander ab, wird also heterogen, was zu inkorrekten Treffermengen bei der Suche nach DDC-erschlossenen Dokumenten führen kann. Eine mögliche Lösung des Problems ist, jeder Version einer DDC-Klasse einen eindeutigen Identifier zuzuordnen und so die Klasse eindeutig identifizieren zu können, mit der ein Titel verknüpft ist. Mit Hilfe von RDF kann aus Titeldaten, Schlagwörtern der Schlagwortnormdatei und den versionierten DDC-Klassen ein semantisches Netzwerk modelliert werden und durch entsprechende Anfragen können genauere Suchergebnisse, unabhängig von Änderungen in der DDC, generiert werden. Die Untersuchungen erfolgten im Rahmen eines Werkvertrages mit der Deutschen Nationalbibliothek und wurden in ausgearbeiteter Form als Masterthesis eingereicht.
