    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
    In 2001, a group of information architects involved in designing websites, and knowledge management specialists involved in creating access to corporate knowledge bases appeared to have re-discovered facet analysis and faceted classification. These groups have been instrumental in creating new and different ways of handling digital content of the Internet. Some of these practitioners explicitly use the forms and language of facet analysis and faceted classification, while others seem to do so implicitly. Following a brief overview of the work and discussions on facets and faceted classification in recent years, we focus on our observations about new information resources which seem more in line with the Fourth law of Library Science ("Save the time of the reader") than most library OPACs today. These new developments on the Internet point to a partial grasp of a disciplined approach to subject access. This is where Ranganathan and Neelameghan's approach needs to be reviewed for the new audience of information system designers. A report on the work undertaken by us forms a principal part of this paper.

    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
    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 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
    Internet information retrieval is largely the preserve of search engines and the even more popular subject trees. Subject trees have adapted principles of conventional bibliographic classification for structuring hierarchic browsing interfaces, thus providing easily used pathways to their selected resources. This combination of browsing and selectivity is especially valuable to untrained users. For the forseeable future, it appears that subject trees will remain the Internet's only practicable use of classificatory methods for information retrieval

    Abstract
    The main object of the paper is to demonstrate in detail the role of classification in information retrieval (IR) and the design of classificatory structures by the application of logical division to all forms of the content of records, subject and imaginative. The natural product of such division is a faceted classification. The latter is seen not as a particular kind of library classification but the only viable form enabling the locating and relating of information to be optimally predictable. A detailed exposition of the practical steps in facet analysis is given, drawing on the experience of the new Bliss Classification (BC2). The continued existence of the library as a highly organized information store is assumed. But, it is argued, it must acknowledge the relevance of the revolution in library classification that has taken place. It considers also how alphabetically arranged subject indexes may utilize controlled use of categorical (generically inclusive) and syntactic relations to produce similarly predictable locating and relating systems for IR.

    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.

    Abstract
    The paper discusses practical methods of apply DDC to digital library services arising from recent technical developments. These include the use of DDC summaries to create hierarchical browsing and tag cloud interfaces, the utility of DDC as a switching language between different subject heading and classification schemes, and the development of terminology servers for interoperability with digital libraries. The focus is on services based in Europe.

    Abstract
    In the Internet information space, advanced information retrieval (IR) methods and automatic text processing are used in conjunction with traditional knowledge organization systems (KOS). New information technology provides a platform for better KOS publishing, exploitation and sharing both for human and machine use. Networked KOS services are now being planned and developed as powerful tools for resource discovery. They will enable automatic contextualisation, interpretation and query matching to different indexing languages. The Semantic Web promises to be an environment in which the quality of semantic relationships in bibliographic classification systems can be fully exploited. Their use in the networked environment is, however, limited by the fact that they are not prepared or made available for advanced machine processing. The UDC was chosen for this research because of its widespread use and its long-term presence in online information retrieval systems. It was also the first system to be used for the automatic classification of Internet resources, and the first to be made available as a classification tool on the Web. The objective of this research is to establish the advantages of using UDC for information retrieval in a networked environment, to highlight the problems of automation and classification exchange, and to offer possible solutions. The first research question was is there enough evidence of the use of classification on the Internet to justify further development with this particular environment in mind? The second question is what are the automation requirements for the full exploitation of UDC and its exchange? The third question is which areas are in need of improvement and what specific recommendations can be made for implementing the UDC in a networked environment? A summary of changes required in the management and development of the UDC to facilitate its full adaptation for future use is drawn from this analysis.

    Abstract
    In 2001, information architects and knowledge management specialists charged with designing websites and access to corporate knowledge bases seemingly re-discovered a legacy form of information organization and access: faceted analytico-synthetic theory (FAST). Instrumental in creating new and different ways for people to engage with the digital content of the Web, the members of this group have clearly recognized that faceted approaches have the potential to improve access to information on the web. Some of these practitioners explicitly use the forms and language of FAST, while others seem to mimic the forms implicitly (Adkisson, 2003). The focus of this ongoing research study is two-fold. First, access and organizational structures in a stratified random sample of 200 DMOZ websites were examined for evidence of the use of FAST. Second, in the context of unstructured interviews, the understanding and use of FAST among a group of eighteen practitioners is uncovered. This is a preliminary report of the website component capture and interview phases of this research study. Future work will involve formalizing a set of feature guidelines drawn from the initial phases of this research study. Preliminary observations will be drawn from the first phase of this study.

    Abstract
    The paper analyses the importance of data presentation and modelling and its role in improving the management, use and exchange of analytico-synthetic classifications in automated systems. Inefficiencies, in this respect, hinder the automation of classification systems that offer the possibility of building compound index/search terms. The lack of machine readable data expressing the semantics and structure of a classification vocabulary has negative effects on information management and retrieval, thus restricting the potential of both automated systems and classifications themselves. The authors analysed the data representation structure of three general analytico-synthetic classification systems (BC2-Bliss Bibliographic Classification; BSO-Broad System of Ordering; UDC-Universal Decimal Classification) and put forward some core requirements for classification data representation

    Abstract
    The structure and use of the classification for books on the amazon.com website are described and analyzed. The contents of this very large website are changing constantly and the access mechanisms have the main purpose of enabling searchers to find books for purchase. This includes finding books the searcher knows about at the start of the search, as well as those that might present themselves in the course of searching and that are related in some way. Underlying the many access paths to books is a classification scheme comprising a rich network of terms in an enumerative and multihierarchical structure.

    Abstract
    Different forms of indexing and search facilities available on the Web are described. Use of facet analysis to structure hypertext concept structures is outlined in relation to work on (1) development of hypertext knowledge bases for designers of learning materials and (2) construction of knowledge based hypertext interfaces. The problem of lack of closeness between page designers and potential users is examined. Facet analysis is suggested as a way of alleviating some difficulties associated with this problem of designing for the unknown user.
    This is a revised version of the earlier article by Ellis and Vasconcelos (1999) (see Not Relevant, below), though that is not indicated, and much of it is identical, word for word. There is a new section covering the work of Elizabeth Duncan, which is useful and informative, but the reader is better advised to go to the originals if available.

    Abstract
    The paper gives a short overview of the history of use of UDC in Internet subject gateways (SGs) with an English interface, from 1993 to 2006. There were in total, nine quality controlled SGs that were functional for shorter or longer periods of time. Their typology and functionality is described. Quality SGs have evolved and the role of classification has changed accordingly from supporting subject organization on the interface and automatic categorization of resources, towards supporting a semantic linking, control and vocabulary mapping between different indexing systems in subject hubs and federated SGs. In this period, many SGs ceased to exist and little information remains available regarding their status. SGs currently using UDC, for some part of their resource organization, do not use a UDC subject hierarchy at the interface and its role in resource indexing has become more difficult to observe. Since 2000, UDC has become more prevalent in East European SGs, portals and hubs, which are outside the scope of this research. This paper is an attempt to provide a record on this particular application of UDC and to offer some consideration of the changes in requirements when it comes to the use of library classification in resource discovery.

    Abstract
    This article describes FAST, the Faceted Application of Subject Terminology, a project at OCLC to make Library of Congress Subject Headings easier to use in Dublin Core metadata by breaking out facets of space, time, and form. Work on FAST can be watched at its web site, http://www.miskatonic.org/library/, which has recent presentations and reports. It is interesting to see facets and Dublin Core combined, though both LCSH and FAST subject headings are beyond what most people making a small faceted classification would want or need.

    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
    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.
