    Abstract
    This paper presents the results of a survey examining the extent to which working catalogers use Classification Web, the Library of Congress' online resource for subject heading and classification documentation. An earlier survey analyzed Class Web's usefulness on an institutional level. This broader survey expands on that analysis and provides information on such questions as: what types of institutions subscribe to Class Web; what are the reasons for using Class Web when performing original or copy cataloging; and what other resources do catalogers use for classification/subject heading analysis?

    Abstract
    This paper presents a study conducted at the University of Colorado at Boulder (CU-Boulder) to assess the extent to which its catalogers were using Classification Web (Class Web), the subscription-based, online cataloging documentation resource provided by the Library of Congress. In addition, this paper will explore assumptions made by management regarding CU-Boulder catalogers' use of the product, possible reasons for the lower-than-expected use, and recommendations for promoting a more efficient and cost-effective use of Class Web at other institutions similar to CU-Boulder.

    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
    This is a report on how Doyle and others made a faceted classification scheme for content management systems and made it browsable on the web (see CMS Review in Example Web Sites, below). They discuss why they did it, how, their use of OPML and XFML, how they did research to find terms and categories, and they also include their taxonomy. It is interesting to see facets used in a business environment.

    Abstract
    Organizing and providing access to the resources an the Internet has been a problem area in spite of the availability of sophisticated search engines and other Software tools. There have been several attempts to organize the resources an the World Wide Web. Some of them have tried to use traditional library classification schemes such as the Library of Congress Classification, the Dewey Decimal Classification and others. However there is a need to assign proper subject headings to them and present them in a logical or hierarchical sequence to cater to the need for browsing. This paper attempts to describe an experimental system designed to organize and provide access to web documents using a faceted pre-coordinate indexing system based an the Deep Structure Indexing System (DSIS) derived from POPSI (Postulate based Permuted Subject Indexing) of Bhattacharyya, and the facet analysis and chain indexing system of Ranganathan. A prototype Software System has been designed to create a database of records specifying Web documents according to the Dublin Core and to input a faceted subject heading according to DSIS. Synonymous terms are added to the Standard terms in the heading using appropriate symbols. Once the data are entered along with a description and the URL of the web document, the record is stored in the System. More than one faceted subject heading can be assigned to a record depending an the content of the original document. The System stores the Surrogates and keeps the faceted subject headings separately after establishing a link. The search is carried out an index entries derived from the faceted subject heading using the chain indexing technique. If a single term is Input, the System searches for its presence in the faceted subject headings and displays the subject headings in a sorted sequence reflecting an organizing sequence. If the number of retrieved Keadings is too large (running into more than a page) the user has the option of entering another search term to be searched in combination. The System searches subject headings already retrieved and looks for those containing the second term. The retrieved faceted subject headings can be displayed and browsed. When the relevant subject heading is selected the system displays the records with their URLs. Using the URL, the original document an the web can be accessed. The prototype system developed in a Windows NT environment using ASP and a web server is under rigorous testing. The database and Index management routines need further development.
    An interesting but somewhat confusing article telling how the writers described web pages with Dublin Core metadata, including a faceted classification, and built a system that lets users browse the collection through the facets. They seem to want to cover too much in a short article, and unnecessary space is given over to screen shots showing how Dublin Core metadata was entered. The screen shots of the resulting browsable system are, unfortunately, not as enlightening as one would hope, and there is no discussion of how the system was actually written or the technology behind it. Still, it could be worth reading as an example of such a system and how it is treated in journals.

    Abstract
    The vision of the semantic web is gradually unfolding and taking shape through a web of linked data, a part of which is built by capturing semantics stored in existing knowledge organization systems (KOS), subject metadata and resource metadata. The content of vast bibliographic collections is currently categorized by some widely used bibliographic classification and we may soon see them being mined for information and linked in a meaningful way across the web. Bibliographic classifications are designed for knowledge mediation, which offers both a rich terminology and different ways in which concepts can be categorized and related to each other in the universe of knowledge. From 1990 to 2010 they have been used in various resource discovery services on the web, and they continue to be used to support information integration in a number of international digital library projects. In this chapter we will revisit some of the ways in which universal classifications, as language-independent concept schemes, can assist humans and computers in structuring and presenting information and formulating queries. Most importantly, we will highlight issues important to understanding bibliographic classifications, identifying both their unused potential and their technical limitations.

    Abstract
    Ab Januar 2006 wird Die Deutsche Bibliothek ein neues Webangebot mit dem Namen Melvil starten, das ein Ergebnis ihres Engagements für die DDC und das Projekt DDC Deutsch ist. Der angebotene Webservice basiert auf der Übersetzung der 22. Ausgabe der DDC, die im Oktober 2005 als Druckausgabe im K. G. Saur Verlag erscheint. Er bietet jedoch darüber hinausgehende Features, die den Klassifizierer bei seiner Arbeit unterstützen und erstmals eine verbale Recherche für Endnutzer über DDCerschlossene Titel ermöglichen. Der Webservice Melvil gliedert sich in drei Anwendungen: - MelvilClass, - MelvilSearch und - MelvilSoap.

    Abstract
    Possibilities are being explored to use traditional bibliographic tools, like Dewey Decimal Classification (DDC), Library of Congress Classification (LCC), Library of Congress Subject Headings (LCSH), and Universal Decimal Classification (UDC), to improve the organization of information resources on the Internet. The most recent edition of DDC, with its enhanced features, has greater potential than other traditional approaches. A review of selected Web sites that use DDC to organize Web resources indicates, however, that the full potential of the DDC scheme for this purpose has not been realized. While the review found that the DDC classification structure was more effective when compared with other knowledge organization systems, we conclude that DDC needs to be further enhanced to make it more suitable for this application. As widely reported in the professional literature, OCLC has conducted research on the potential of DDC for organizing Web resources. Such research, however, is experimental and should be supplemented by empirical studies with user participation.

    1. Introduction Web search engines and digital libraries usually expect the users to use search terms that most accurately represent their information needs. Finding the most appropriate search terms to represent an information need is an age old problem in information retrieval. Keyword or phrase search may produce good search results as long as the search terms or phrase(s) match those used by the authors and have been chosen for indexing by the concerned information retrieval system. Since this does not always happen, a large number of false drops are produced by information retrieval systems. The retrieval results become worse in very large systems that deal with millions of records, such as the Web search engines and digital libraries. Vocabulary control tools are used to improve the performance of text retrieval systems. Thesauri, the most common type of vocabulary control tool used in information retrieval, appeared in the late fifties, designed for use with the emerging post-coordinate indexing systems of that time. They are used to exert terminology control in indexing, and to aid in searching by allowing the searcher to select appropriate search terms. A large volume of literature exists describing the design features, and experiments with the use, of thesauri in various types of information retrieval systems (see for example, Furnas et.al., 1987; Bates, 1986, 1998; Milstead, 1997, and Shiri et al., 2002).

    Abstract
    Two library classification system interfaces have been implemented for navigating and searching large collections of document and book records. One interface allows the user to browse book records organized by the DDC hierarchy. A Book Shelf display reflects the facet position in the classification hierarchy during browsing, and it dynamically updates to reflect search hits and attribute selections. The other interface provides access to records describing computer science documents classified by the ACM Computing Reviews (CR) system. The CR classification system is a type of faceted classification in which documents can appear at several points in the hierarchy. These two interfaces demonstrate that classification structure can be effectively utilized for organizing digital libraries and, potentiall, collections of Internet-wide information services

    Abstract
    In free classification, each concept is expressed by a constant notation, and classmarks are formed by free combinations of them, allowing the retrieval of records from a database by searching any of the component concepts. A refinement of free classification is freely faceted classification, where notation can include facets, expressing the kind of relations held between the concepts. The Integrative Level Classification project aims at testing free and freely faceted classification by applying them to small bibliographical samples in various domains. A sample, called the Dandelion Bibliography of Facet Analysis, is described here. Experience was gained using this system to classify 300 specialized papers dealing with facet analysis itself recorded on a MySQL database and building a Web interface exploiting freely faceted notation. The interface is written in PHP and uses string functions to process the queries and to yield relevant results selected and ordered according to the principles of integrative levels.

    Abstract
    Terms drawn from DDC indexes and IEEE Web Thesaurus were merged with DDC hierarchies to build a taxonomy in the domain of computer science. When displayed as a directory structure using a shareware tool MyInfo, the resultant taxonomy appeared to be a promising tool for categorisation that can facilitate browsing of information resources in an electronic environment.

    Abstract
    Edited version of a report to the Australian Library and Information Association on the Conference on classification theory in the computer age, Albany, New York, 18-19 Nov 88, and on the meeting of the Dewey Editorial Policy Committee which preceded it. The focus of the Editorial Policy Committee Meeting lay in the following areas: browsing; potential for improved subject access; system design; potential conflict between shelf location and information retrieval; and users. At the Conference on classification theory in the computer age the following papers were presented: Applications of artificial intelligence to bibliographic classification, by Irene Travis; Automation and classification, By Elaine Svenonious; Subject classification and language processing for retrieval in large data bases, by Diana Scott; Implications for information processing, by Carol Mandel; and implications for information science education, by Richard Halsey.

    Abstract
    This article gives an overview of the design and organisation of DutchESS, a Dutch information subject gateway created as a national collaborative effort of the National Library and a number of academic libraries. The combined centralised and distributed model of DutchESS is discussed, as well as its selection policy, its metadata format, classification scheme and retrieval options. Also some options for future collaboration on an international level are explored
