    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
    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
    This paper examines some traditional information searching methods and their role in Hungarian OPACs. What challenges are there in the digital and online environment? How do users work with them and do they give users satisfactory results? What kinds of techniques are users employing? In this paper I examine the user interfaces of UDC, thesauri, subject headings etc. in the Hungarian library. The key question of the paper is whether a universal system or local solutions is the best approach for searching in the digital environment.

    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
    Although researchers have theorized the critical importance of classification in the organization of information, the classification approach seems to have given way to the alphabetical subject approach in retrieval tools widely used in libraries, and research an how users utilize classification or classification-like arrangements in information seeking has been scant. To better understand whether searchers consider classificatory structures a viable alternative to information retrieval, this article reports an a study of how 24 library and information science students used Yahoo! directories, a popular search service resembling classification, in completing an assigned simple task. Several issues emerged from the students' reporting of their search process and a comparison between hierarchical navigation and keyword searching: citation order of facets, precision vs. recall, and other factors influencing searchers' successes and preferences. The latter included search expertise, knowledge of the discipline, and time required to complete the search. Without a definitive conclusion, we suggest a number of directoons for further research.

    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 nature of search requirements is perceived to be changing, fuelled by a growing dissatisfaction with the marginal accuracy and often overwhelming quantity of results from simple keyword matching techniques. Traditional search interfaces fail to acknowledge and utilise the implicit underlying structure present within a typical keyword query. Faceted structure can (and should) perform a significant role in this area - acting as the basis for mediation between searcher and indexer, and guiding query formulation and reformulation by interactively educating the user about the native domain. This paper discusses the possible benefits of applying faceted knowledge organization systems to enhance query structure, query visualisation and the overall query process, drawing an the outcomes of a recently completed research project.

    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 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.

    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
    This paper examines the differences in the functional requirements of a faceted classification system when used in a conventional print-based environment (where the emphasis is on the browse function of the classification) as compared to its application to digital collections (where the retrieval function is paramount). The use of the second edition of Bliss's Bibliographic Classification (BC2) as a general classification for the physical organization of undergraduate collections in the University of Cambridge is described. The development of an online tool for indexing of digital resources using the Bliss terminologies is also described, and the advantages of facet analysis for data structuring and system syntax within the prototype tool are discussed. The move from the print-based environment to the digital makes different demands an both the content and the syntax of the classification, and while the conceptual structure remains similar, manipulation of the scheme and the process of content description can be markedly different.

    Abstract
    This paper aims to explore the changes in the role of classification and the opportunities presented for classification in the twenty-first century, especially in respect to the development of information technology. The issues arose as part of the EC funded MIRACLE project that represents the foundation for a virtual music library to serve visually impaired people. The MIRACLE partners chose the UDC as the common classification for the converging music catalogues. This paper investigates the nature of adaptation required by each participating library and the way in which the classification is used as a searching tool. Further developments in the use of IT-assisted classification are proposed

    Abstract
    At the end of 2005, impending digitization efforts and several developments related to the creation of access and discovery tools for informational and cultural objects resulted in a series of responses that continue to ripple throughout the library, museum and archive communities. These developments have broad implications for all three communities because of the goals shared by each in the creation of description, control and enhanced access to informational and cultural objects. This position paper will consider new implementations of faceted navigation and browsing features in online catalogs. It is also a response to challenges to develop interwoven approaches to the study of information seeking and the design and implementation of search and discovery systems. Urgently needed during this time of experimentation, development and implementation is a framework for system evaluation and critical analysis of needed and missing features that is grounded in traditional principles, borne out by practice. Such a framework could extend feature analysis protocols established during the early years of online catalog development.

    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.

    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.
