Abstract

Erschließungsinstrumente erhöhen Effizienz und Effektivität thematischer Recherchen, indem sie standardisierte Zugänge zu Informationsressourcen bieten und mittels Ausweisung von Begriffsbeziehungen explorative Suchprozesse unterstützen. In heterogenen Informationsräumen ist ihre Funktionalität aufgrund der Unterschiedlichkeit der verwendeten Indexierungsdaten indes begrenzt. Die Herstellung von Verbindungen zwischen Dokumentationssprachen trägt dazu bei, dass das mit einem einzelnen Begriffssystem gegebene Potential über Teilmengen hinaus nutzbar wird. Welcher Mehrwert durch eine adäquate Einbindung derartiger Verknüpfungen in Retrievalapplikationen im Einzelnen erzielt werden kann, ist wesentlich abhängig von der zugrunde liegenden Methode der Heterogenitätsbehandlung und den berücksichtigten Charakteristika der jeweiligen Erschließungsinstrumente. Im Folgenden wird der vom DFG-Projekt CrissCross praktizierte Ansatz zur Herstellung von semantischer Interoperabilität zwischen der Schlagwortnormdatei (SWD) und der Dewey-Dezimalklassifikation (DDC) vorgestellt und sein Nutzen zur Unterstützung thematischer Suchprozesse aufgezeigt.
