    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
    The Hierarchical Interface to Library of Congress Classification (HILCC) is a system developed by the Columbia University Library to leverage call number data from the MARC holdings records in Columbia's online catalog to create a structured, hierarchical menuing system that provides subject access to the library's electronic resources. In this paper, the authors describe a research initiative at the Cornell University Library to discover if the Columbia HILCC scheme can be used as developed or in modified form to create a virtual undergraduate print collection outside the context of the traditional online catalog. Their results indicate that, with certain adjustments, an HILCC model can indeed, be used to represent the holdings of a large research library's undergraduate collection of approximately 150,000 titles, but that such a model is not infinitely scalable and may require a new approach to browsing such a large information space.

    Abstract
    Networked orientated standards for vocabulary publishing and exchange and proposals for terminological services and terminology registries will improve sharing and use of all knowledge organization systems in the networked information environment. This means that documentary classifications may also become more applicable for use outside their original domain of application. The paper summarises some characteristics common to documentary classifications and explains some terminological, functional and implementation aspects. The original purpose behind each classification scheme determines the functions that the vocabulary is designed to facilitate. These functions influence the structure, semantics and syntax, scheme coverage and format in which classification data are published and made available. The author suggests that attention should be paid to the differences between documentary classifications as these may determine their suitability for a certain purpose and may impose different requirements with respect to their use online. As we speak, many classifications are being created for knowledge organization and it may be important to promote expertise from the bibliographic domain with respect to building and using classification systems.

    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

    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
    A model system, the Dewey Online Retrieval System (DORS), was implemented as an interface to an online catalog for the purpose of experimenting with classification-based search strategies and generally seeking further understanding of the role of traditional classifications in automated information retrieval. Specifications for a classification retrieval interface were enumerated and rationalized and the system was developed in accordance with them. The feature that particularly distinguishes the system and enables it to meet its stated specifications is an automatically generated chain index

    Abstract
    In order to enhance the use of Universal Decimal Classification (UDC) numbers in information retrieval, the authors have represented classification with multilingual thesaurus descriptors and implemented this solution in an automated way. The authors illustrate a solution implemented in a BiblioPhil library system. The standard formats used are UNIMARC for subject authority records (i.e. the UDC-based multilingual thesaurus) and MARC XML support for data transfer. The multilingual thesaurus was built according to existing standards, the constituent parts of the classification notations being used as the basis for search terms in the multilingual information retrieval. The verbal equivalents, descriptors and non-descriptors, are used to expand the number of concepts and are given in Romanian, English and French. This approach saves the time of the indexer and provides more user-friendly and easier access to the bibliographic information. The multilingual aspect of the thesaurus enhances information access for a greater number of online users

    Abstract
    Van Dijck builds up an example of actual XFML by showing how to organize tourist information about what restaurants in what cities feature which kind of music: <facet id="city">City</facet> and <topic id="ny" facetid="city"><name>New York</name></topic> combine to mean that New York is the name of a city internally represented as "ny". It is written in the usual clear and practical style of articles on xml.com. Highly recommended as an introduction for anyone interested in XFML.

    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
    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
    We live in an information age that requires us, more than ever, to represent, access, and use information. Over the last several decades, we have developed a modern science and technology for information retrieval, relentlessly pursuing the vision of a "memex" that Vannevar Bush proposed in his seminal article, "As We May Think." Faceted search plays a key role in this program. Faceted search addresses weaknesses of conventional search approaches and has emerged as a foundation for interactive information retrieval. User studies demonstrate that faceted search provides more effective information-seeking support to users than best-first search. Indeed, faceted search has become increasingly prevalent in online information access systems, particularly for e-commerce and site search. In this lecture, we explore the history, theory, and practice of faceted search. Although we cannot hope to be exhaustive, our aim is to provide sufficient depth and breadth to offer a useful resource to both researchers and practitioners. Because faceted search is an area of interest to computer scientists, information scientists, interface designers, and usability researchers, we do not assume that the reader is a specialist in any of these fields. Rather, we offer a self-contained treatment of the topic, with an extensive bibliography for those who would like to pursue particular aspects in more depth.

    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
    Summarizes some experiences of the application of the priciples and postulates of S.R. Ranganathan's General Theory of Knowledge Classification, incorporating the freely faceted approach and analytico synthetic methods, to the design and development of specialized databases, including indexing, user interfaces and retrieval. Enumerates some of the earlier instances of the facet method in machine based systems, beginning with Hollerith's punched card system for the data processing of the US Census. Elaborates on Ranganathan's holistic approach to information systems and services provided by his normative principles. Notes similarities between the design of databases and faceted classification systems. Examples from working systems are given to demonstrate the usefulness of selected canons and principles of classification and the analytico synthetic methodology to database design. The examples are mostly operational database systems developed using Unesco's Micro CDS-ISIS software

    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.
