Abstract

Die verstärkte Diskussion über qualitativ bessere Such- und Erschließungsmethoden im Internet führt auch dazu, dass Thesauri und Klassifikation bei Fachanbietern und im wissenschaftlich-bibliothekarischen Bereich verstärkt wieder Thema und auch Gegenstand von Projekten geworden sind. Solche Konjunkturschwankungen sind ein bekanntes Phänomen, denn schon immer haben fachlich-methodische Instrumente in Zeiten technologischer Schübe schlechte Konjunktur. Wenn die technologischen Machbarkeiten dann kritisch überdacht werden müssen und die Probleme der Qualitätssicherung ins Auge fallen, rückt das Problem der Vermittlung technologischer Verfahren mit sach- und inhaltsbezogenen Anforderungen unweigerlich wieder stärker in den Mittelpunkt des Interesses'. Meine Ausführungen richten sich vor allem auf aktuelle Probleme der Produktion und Wiedergewinnung von Informationen oder präziser: von Fachinformationen, Fragen der Qualitätssicherung und die Rolle, die Klassifikationen und Thesauri in diesem Zusammenhang spielen oder spielen könnten. Insbesondere der Aspekt der Nutzerakzeptanz wird hier stärker thematisiert. Der Punkt nettere Ansätze wird etwas eingehender am Beispiel der Vernetzung verschiedener Thesauri und Klassifikationen mittels sogenannter Cross-Konkordanzen erläutert. Im Folgenden beziehe ich mich vor allem auf die Sozialwissenschaften und insbesondere die Erziehungswissenschaft. Dies ist der fachliche Background des Fachinformationssystem Bildung, und des Deutschen Bildungsservers in deren Kontext ich mit den hier angesprochenen Problemen befasst bin

Abstract

Once the library has been through a process of transition from traditional library procedures to automated ones, natural language searching became a necessity for both indexers and searchers. Therefore, aside from the precoordinated classified catalogue we started to build a dictionary of terms in order to make postcoordinate search possible in keeping with the UDC notations assigned to each bibliographic record. After a while we came to the conclusion that the dictionary needed a control of its terms so that synonymous concepts and semantic ambuguities be avoided. The project presented in this paper shows how reality imposed the improvement of the quality of indexing and hence of the searching possibilities. Is also shows the reasons why we consider a multilingual thesaurus based on UDC an ideal indexing and searching device. The experiment applied on class 8 of UDC illustrates the way the UDC tables can be quite successfully used in building a thesaurus due to their qulities and how their limitations can be overcome by a thesaurus. An appendix to the paper contains a sample of the multilingual thesaurus given in both alphabetical and systematic layouts
