Abstract: Ideally, intersystem relations complement highly expressive and thoroughly structured relational indexing languages. The relational structures of the participating systems contribute to the meaning of the individual terms or classes. When conceptualizing mapping relations the structural and functional design of the respective systems must be fully taken into account. As intersystem relations may differ considerably from familiar interconcept relations, the creation of an adequate inventory that is general in coverage and specific in depth demands a deep understanding of the requirements and properties of mapping relations. The characteristics of specific mapping relations largely rely on the characteristics of the systems they are intended to connect. The detailed declaration of differences and peculiarities of specific mapping relations is an important prerequisite for modelling these relations. First approaches towards specifying

Der zweite Tag begann mit einer Keynote von Dagobert Soergel von der University at Buffalo mit dem Thema Conceptual Foundations for Semantic Mapping and Semantic Search. Im Zentrum stand die Idee eines Hubs, einer semantischen Verbindungsstruktur in Form einer Kernklassifikation, die elementare Begriffe sowie semantische Relationen enthält und über die ein Mapping zwischen unterschiedlichen Wissensorganisationssystemen erfolgen soll. Die Methode wurde durch zahlreiche Beispiele veranschaulicht. Die erste Session des zweiten Tages war dem Thema Interoperabilität und Standardisierung gewidmet. Stella Dextre Clarke aus Großbritannien berichtete - ausgehend von den in zentralen Mappingprojekten erstellten Relationen zwischen Begriffen unterschiedlicher Dokumentationssprachen - über Herausforderungen und Fragestellungen bei der Entwicklung des neuen ISO-Standards 25964-2, der als Leitfaden zur Herstellung von Interoperabilität zwischen Thesauri und anderen Vokabularien fungieren soll. In dem Folgevortrag von Philipp Mayr vom GESIS Leipniz-Institut für Sozialwissenschaften wurd mit KoMoHe (Kompetenzzentrum Modellbildung und Heterogenitätsbehandlung) ein bereits abgeschlossenes Projekt vorgestellt, dessen Mehrwert für das Retrieval in heterogen erschlossenen Informationsräumen mittels eines Information-Retrieval-Tests bestätigt werden konnte. Unpräzise Trefferresultate motivierten indes zu dem Nachfolgeprojekt IRM (Value-Added Services for Information Retrieval), in dem Möglichkeiten von Suchexpansion und Re-Ranking untersucht werden.

Abstract: Within the frame of the methodological support of the CrissCross project and the research conducted in the Reseda project, a tiered model of semantic interoperability was developed. This correlates methods of establishing semantic interoperability and types of intersystem relations to search functionalities in retrieval scenarios. In this article the model is outlined and exemplified with reference to respective selective alignment projects.

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.
