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.

Abstract

As an important support tool in science research, specialized information systems are rapidly changing their character. The potential for improvement compared with today's usual systems is enormous. This fact will be demonstrated by means of two problem complexes: - WWW search engines, which were developed without any government grants, are increasingly dominating the scene. Does the WWW displace information centers with their high quality databases? What are the results we can get nowadays using general WWW search engines? - In addition to the WWW and specialized databases, scientists now use WWW library catalogues of digital libraries, which combine the catalogues from an entire region or a country. At the same time, however, they are faced with highly decentralized heterogeneous databases which contain the widest range of textual sources and data, e.g. from surveys. One consequence is the presence of serious inconsistencies in quality, relevance and content analysis. Thus, the main problem to be solved is as follows: users must be supplied with heterogeneous data from different sources, modalities and content development processes via a visual user interface without inconsistencies in content development, for example, seriously impairing the quality of the search results, e. g. when phrasing their search inquiry in the terminology to which they are accustomed

Abstract

The trend in the fifties and sixties of the past century away from the use of universal classification systems such as the UDC towards establishing thesauri in special subject fields for the description of the conceptual contents of documents lead documentalists soon to realize that the necessary common tool for a collaboration among centers of similar subject fields was lacking. Therefore compatibility and integration studies began between the different thesauri of such fields, leading often to more comprehensive thesauri, such as macrothesauri. The paper describes this historic development and also the solutions found at the 1995 ISKO-Conference in Warsaw/Poland on Compatibility and Integration as given in its papers, its recommendations and also in the conceptual frame of its comprehensive bibliography on this topic. In conclusion a new solution is presented oriented toward combining the use of a universal classification system with the new developments of ontologies and their problem of interoperability and heterogeneity.
