    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

    Abstract
    Die traditionellen Verfahren der klassifikatorischen sachlichen Erschließung von Medieninhalten heben auf die Eindeutigkeit der Zuordnung von Objekt (Medieninhalt) und Klasse ab. Sie unterscheiden sich damit in der Praxis des Online-Retrievals nur unwesentlich von den Verfahren der verbalen sachlichen Erschließung (z.B. Thesauri, SWD/RSWK). Auf der Grundlage der in der Sacherschließungstheorie vorgenommenen Unterscheidung von klassifikatorischer und verbaler Sacherschließung werden mögliche und bereits in Anwendung befindliche Verfahren diskutiert, welche die begrifflichen Kontexte der Klassen für den Anwender einer bibliothekarischen Klassifikation im Online-Retrieval nutzbar machen

    Abstract
    Für die Recherchen in den Datenbanken FORIS und SOLIS bietet das IZ verschiedene Einstiegsmöglichkeiten, die - abhängig von der Fragestellung - einzeln oder kombiniert genutzt werden können: bibliographische Elemente, wie z.B. Namen von Autoren oder Projektleitern, Erscheinungsjahre von Veröffentlichungen oder Laufzeiten von Projekten, sowie inhaltlich orientierte Einstiege, wie z.B. Textrecherchen, Klassifikationen oder Schlagwörter

    Abstract
    The automation of Bucharest University Central Library involved the compilation of a dictionary of terms to facilitate postcoordinated searching in accordance with the UDC notation attached to every bibliographic record. Describes the project and demonstrates why a multilingual UDC based thesaurus is considered as ideal indexing and searching tool. The experiment, which applied to Class 8 of UDC (Linguisitcs and Literature), illustrates how all UDC tables can be successfully used to build a thesaurus and the ways in which their limitations can be overcome by a thesaurus

    Abstract
    Die intellektuelle Erschließung des Internet befindet sich in einer Krise. Yahoo und andere Dienste können mit dem Wachstum des Web nicht mithalten. GERHARD ist derzeit weltweit der einzige Such- und Navigationsdienst, der die mit einem Roboter gesammelten Internetressourcen mit computerlinguistischen und statistischen Verfahren auch automatisch vollständig klassifiziert. Weit über eine Million HTML-Dokumente von wissenschaftlich relevanten Servern in Deutschland können wie bei anderen Suchmaschinen in der Datenbank gesucht, aber auch über die Navigation in der dreisprachigen Universalen Dezimalklassifikation (ETH-Bibliothek Zürich) recherchiert werden

    Abstract
    Facettenklassifikationen wurden bislang vorwiegend im Hinblick auf ihre Verwendungsmöglichkeiten in präkombinierten systematischen Katalogen bzw. Bibliographien betrachtet, nicht so sehr unter dem Aspekt eines möglichen Einsatzes in postkoordinierenden Retrievalsystemen. Im vorliegenden Beitrag soll nachgewiesen werden, daß Facettenklassifikationen anderen Techniken des Online Retrievals überlegen sein können. Hierzu sollten Begriffs- und Facettenanalyse mit einem strukturabbildenden Notationssystem kombiniert werden, um mit Hilfe Boolescher Operatoren (zur Verknüpfung von Facetten unabhängig von einer definierten Citation order) und Truncierung hierarchisch differenzierte Dokumentenmengen für komplexe Fragestellungen zu erhalten. Die Methode wird an zwei Beispielen illustriert: das erste nutzt eine kleine, von B. Buchanan entwickelte Klassifikation, das zweite das für Library and Information Science Abstracts (LISA) verwendete Klassifikationssystem. Weiter wird am Beispiel PRECIS diskutiert, welche Möglichkeiten des syntaktischen Retrievals Rollenoperatoren bieten können.

    Abstract
    Eine ganze Anzahl von Bibliotheken in Europa befaßt sich mit der Entwicklung von Internet Subject Gateways - einer Serviceleistung, die den Nutzern helfen soll, qualitativ hochwertige Internetquellen zu finden. Subject Gateways wie SOSIG (The Social Science Information Gateway) sind bereits seit einigen Jahren im Internet verfügbar und stellen eine Alternative zu Internet-Suchmaschinen wie AltaVista und Verzeichnissen wie Yahoo dar. Bezeichnenderweise stützen sich Subject Gateways auf die Fertigkeiten, Verfahrensweisen und Standards der internationalen Bibliothekswelt und wenden diese auf Informationen aus dem Internet an. Dieses Referat will daher betonen, daß Bibliothekare/innen idealerweise eine vorherrschende Rolle im Aufbau von Suchservices für Internetquellen spielen und daß Information Gateways eine Möglichkeit dafür darstellen. Es wird einige der Subject Gateway-Initiativen in Europa umreißen und die Werkzeuge und Technologien beschreiben, die vom Projekt DESIRE entwickelt wurden, um die Entwicklung neuer Gateways in anderen Ländern zu unterstützen. Es wird auch erörtert, wie IMesh, eine Gruppe für Gateways aus der ganzen Welt eine internationale Strategie für Gateways anstrebt und versucht, Standards zur Umsetzung dieses Projekts zu entwickeln

    Abstract
    Dagobert Soergel opened the discussion by saying, "Users need our help to find and make sense of information." He said that he believes that classification can provide much of the support users need. He sees little distinction between the concept of a thesaurus and that of classification since both seek to provide structure for knowledge bases in order to facilitate information retrieval. Soergel's discussion of his concept of a multifunctional, multilingual thesaurus comprised the bulk of his presentation. This thesaurus would be a database of concepts, terms, and relationships which would include classification. In this context, classification has a much broader set of functions than it currently does in most American libraries where classification serves primarily as a method of shelf arrangement. The thesaurus Soergel envisions would lay out the semantic map of a field and could therefore be used as a learning tool or as a basis for research planning, or to assist users in clarifying terms and concepts. It could support indexing and searching and provide for the organization of knowledge for expert systems and other artificial intelligence applications. Among its other features, such a thesaurus could assist users in making sense of information by providing structured presentation of search results based on user needs and preferences, and it could enhance natural language processing capabilities such as automated indexing and abstracting and machine translation.

    Abstract
    Die Methoden zur formalen und inhaltlichen Erschließung von Medienbeständen in Bibliotheken wurden ausnahmslos vor dem Hintergrund der konventionellen Katalogisierung entwickelt und optimiert. Durch den zunehmenden Einsatz der Computertechnologie in Bibliotheken wird eine kritische Überprüfung der tradierten Erschließungsmethoden erforderlich. Gegenstand dieser Untersuchung ist die bibliothekarische Klassifikation und ihre Verwendung in Online-Publikums-Katalogen (OPAC) und anderen Information-Retrieval-Systemen (IRS). Auf der Grundlage der bibliothekarischen Klassifikationstheorie erfolgt eine Überprüfung der verschiedenen Klassifikationstypen hinsichtlich ihrer Tauglichkeit für die gängigen Recherche-Funktionen in diesen Systemen. Zusätzlich wird ein Anforderungskatalog für die Schlagwort-Register und -indizes entwickelt, der im Online-Dialog den verbalen Zugriff auf die einzelnen Klassen einer bibliothekarischen Klassifikation sicherstellen soll
