Abstract
Wissensorganisationssysteme unterstützen inhaltsbezogene Recherche- und Explorationsprozesse, indem sie a priori Beziehungen zwischen Begriffen ausweisen und einen standardisierten Zugriff auf Informationen ermöglichen. In heterogen erschlossenen Informationsräumen ist ihre Funktionalität indes eingeschränkt, da sie lediglich die Suche nach den Informationsressourcen, die mit ihnen erschlossen wurden, effizienter gestalten. Dokumente, deren inhaltliche Beschreibung auf der Grundlage von sprachlich, strukturell und typologisch unterschiedlichen Begriffssystemen erfolgte, werden hingegen nicht gefunden. Dies führt zu einem unzureichenden Recall und macht zusätzliche Recherchen notwendig. Mittels der Herstellung von Verbindungen zwischen Begriffen unterschiedlicher Dokumentationssprachen wird der standardisierte Zugriff auf Informationen erweitert und das Potential einzelner Erschließungsinstrumente über Teilmengen hinaus nutzbar. Vor dem Hintergrund, über welche inhaltlichen Qualitäten die erstellten Links verfügen, lassen sich drei Arten semantischer Interoperabilität unterscheiden, die mit jeweils anderen Implikationen für Retrievalszenarien einhergehen: wortbasierte, begriffliche und differenzierte Interoperabilität.
In dem von der Deutschen Forschungsgemeinschaft (DFG) geförderten und von der Deutschen Nationalbibliothek (DNB) in Kooperation mit der Fachhochschule Köln durchgeführten Projekt CrissCross wird eine begriffliche und differenzierte Interoperabilität zwischen der Schlagwortnormdatei (SWD) und der Dewey- Dezimalklassifikation (DDC) realisiert. In diesem Beitrag wird unter Berücksichtigung der Charakteristika der beiden Begriffssysteme dargelegt, welche Möglichkeiten die SWD-DDC-Mappings sowohl zur Unterstützung von inhaltsbezogenen Such- und Explorationsprozessen als auch zur Strukturierung von Treffermengen bieten.
