- Abstract
- Knowledge organization systems (KOS), like thesauri and other controlled vocabularies, are used to provide subject access to information systems across the web. Due to the heterogeneity of these systems, mapping between vocabularies becomes crucial for retrieving relevant information. However, mapping thesauri is a laborious task, and thus big efforts are being made to automate the mapping process. This paper examines two mapping approaches involving the agricultural thesaurus AGROVOC, one machine-created and one human created. We are addressing the basic question "What are the pros and cons of human and automatic mapping and how can they complement each other?" By pointing out the difficulties in specific cases or groups of cases and grouping the sample into simple and difficult types of mappings, we show the limitations of current automatic methods and come up with some basic recommendations on what approach to use when.

- Abstract
- Die Vernetzung der Informationssysteme und Datenbanken aus dem wissenschaftlichen Fachinformationsbereich lässt bislang den Aspekt der Kompatibilität und Konkordanz zwischen kontrollierten Vokabularen (semantische Heterogenität) weitgehend unberücksichtigt. Gerade aber für den inhaltlichen Zugang sachlich heterogen erschlössener Bestände spielen für den Nutzer die semantischen Querverbindungen (Mappings /Crosskonkordanzen) zwischen den zugrunde liegenden Knowledge Organization Systems (KOS) der Datenbanken eine entscheidende Rolle. Der Beitrag stellt Einsatzmöglichkeiten und Beispiele von Crosskonkordanzen (CK) im Projekt "Kompetenznetzwerk Modellbildung und Heterogenitätsbehandlung" (KoMoHe) sowie das Netz der bis dato entstandenen Terminolögie-Überstiege vor. Die am IZ entstandenen CK sollen künftig über einen Terminolögie-Service als Web Service genutzt werden, dieser wird im Beitrag exemplarisch vorgestellt.
