    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
    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

    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
    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
