    Abstract
    The Wolverhampton Web Library (WWLib) is a WWW search engine that provides access to UK based information. The experimental version developed in 1995, was a success but highlighted the need for a much higher degree of automation. An interesting feature of the experimental WWLib was that it organised information according to DDC. Discusses the advantages of classification and describes the automatic classifier that is being developed in Java as part of the new, fully automated WWLib

    Abstract
    Creates an open, metadata aware system for distributed, collaborative WWW indexing. The system has 3 main components: a harvester (for collecting information), a database (for making the collection searchable), and a user interface (for making the information available). all components can be distributed across networked computers, thus supporting scalability. The system is metadata aware and thus allows searches on several fields including title, document author and URL. Nordic Web Index (NWI) is an application using this system to create a regional Nordic Web-indexing service. NWI is built using 5 collaborating service points within the Nordic countries. The NWI databases can be used to build additional services

    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
    For generations, libraries have facilitated access to information sources by the development and use of a wide range of appropriate organizational processes. Within a Web-based demonstration prototype, we have applied several established library procedures, principles and practices to enhance access to selected Internet resources in science and technology. In seeking to manage these sources, we have established defined collection, adopted an established library classification scheme as an organizational framework, and sought to stimulate the features and functions of a physical library collection and conventional reference sourcees. This paper describes the key components of this prototype, reviews research which supports its approach, and profiles suggested enhancements which could further facilitate identification, access and use of significant Internet and WWW resources

    Abstract
    This article gives a cheerfully brief and undetailed account of how to make a faceted classification system, then describes information retrieval and searching on the web. It concludes by saying that facets would be excellent in helping users search and browse the web, but offers no real clues as to how this can be done.

    Abstract
    The study of faceted classification systems has primarily been directed towards application for precombined catalogues or bibliographies, not so much for use in post coordinated retrieval systems. Argues that faceted classification systems in some respects are superior to other techniques of on-line retrieval as far as facet and concept analysis is combined with an expressive notational system in order to guide a form of retrieval which will use Boolean operators (for combining the facets regardless of one special citation order) and truncation for retrieving hierarchically different sets of documents. This point of view is demonstrated by 2 examples. The 1st one uses a short classification system derived from B. Buchanan and the 2nd is built upon the classification system used by Library and Information Science Abstracts (LISA). Further discussion is concerned with some possible consequences which could be derived from a retrieval with PRECIS strings
    "Online retrieval" conjures up a very different mental image now than in 1991, the year this article was written, and the year Tim Berners-Lee first revealed the new hypertext system he called the World Wide Web. Gödert shows that truncation and Boolean logic, combined with notation from a faceted classification system, will be a powerful way of searching for information. It undoubtedly is, but no system built now would require a user searching for material on "nervous systems of bone fish" to enter "Fdd$ and Leaa$". This is worth reading for someone interested in seeing how searching and facets can go together, but the web has made this article quite out of date.

    Abstract
    The explosion of the use of the Internet by the genral public, particularly via the WWW, has given rise to the proliferation of semiprofessional attempts to give some subject based access to Internet resources via hierarchical guides (hotlists) on Web search engines such as Yahoo and Magellan. Examines the structure and principles of various hierachical lists, and compares them, when possible, to broad LCC and DDC schemes, and to LCSH. Explores the approaches taken by non librarians in their efforts to organize and provide access to materials on the Internet. Focuses on the dichotomy between the hierarchical 'browse' and the analytical 'search' approaches to finding materials, as exemplified by these various attempts to organize the Internet

    Abstract
    Describes the shortcomings of search engines for the WWW comparing their current capabilities to those of the first generation CD-ROM products. Some allow phrase searching and most are improving their Boolean searching. Few allow truncation, wild cards or nested logic. They are stateless, losing previous search criteria. Unlike the indexing and classification systems for today's CD-ROMs, those for Web pages are random, unstructured and of variable quality. Considers that at best Web search engines can only offer free text searching. Discusses whether automatic data classification systems such as Infoseek Ultra can overcome the haphazard nature of the Web with neural network technology, and whether Boolean search techniques may be redundant when replaced by technology such as the Euroferret search engine. However, artificial intelligence is rarely successful on huge, varied databases. Relevance ranking and automatic query expansion still use the same simple inverted indexes. Most Web search engines do nothing more than word counting. Further complications arise with foreign languages

    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.
