    Abstract
    Conceptual Knowledge Markup Language (CKML), an application of XML, is a new standard being promoted for the specification of online conceptual knowledge (Kent and Shrivastava, 1998). CKML follows the philosophy of Conceptual Knowledge Processing (Wille, 1982), a principled approach to knowledge representation and data analysis, which advocates the development of methodologies and techniques to support people in their rational thinking, judgement and actions. CKML was developed and is being used in the WAVE networked information discovery and retrieval system (Kent and Neuss, 1994) as a standard for the specification of conceptual knowledge

    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
    Once the library has been through a process of transition from traditional library procedures to automated ones, natural language searching became a necessity for both indexers and searchers. Therefore, aside from the precoordinated classified catalogue we started to build a dictionary of terms in order to make postcoordinate search possible in keeping with the UDC notations assigned to each bibliographic record. After a while we came to the conclusion that the dictionary needed a control of its terms so that synonymous concepts and semantic ambuguities be avoided. The project presented in this paper shows how reality imposed the improvement of the quality of indexing and hence of the searching possibilities. Is also shows the reasons why we consider a multilingual thesaurus based on UDC an ideal indexing and searching device. The experiment applied on class 8 of UDC illustrates the way the UDC tables can be quite successfully used in building a thesaurus due to their qulities and how their limitations can be overcome by a thesaurus. An appendix to the paper contains a sample of the multilingual thesaurus given in both alphabetical and systematic layouts

    Abstract
    There exist in the world many bibliographical databases, which are indexed with the UDC. Searching in the databases is difficult for everyone not very experienced in the use of this classification scheme. The notations can be very complex and often it would be desirable to be able to search on only a part of the notation. In this paper algorithms for the decomposition of complex UDC-notations and adding a description to the resulting simple notations are discussed. In the second part of the paper the resulting texts are discussed

    Abstract
    The purpose of this paper is to determine some of the structural features of the classification schemes used in the directories (guides, channels) of search engines to organise information sources on the Internet. Ten search engines were examined at the main class level and the full hierarchies of a sample of three specific subjects were analysed in four of these engines, namely Excite, Infoseek, Lycos and Yahoo! It was found that there are major differences between the main classes of the search engines and those found in standard library schemes like Dewey, UDC and LCC. There are large gaps in subject coverage at main class level in the search engines and the general tendency is to use a topic-based approach in the formation of classes, rather than a discipline-based approach. The subdivision of the main classes is according to hierarchical tree structures, but a number of anomalies in this regard were identified. Another deviation from library classification theory is that various principles of division are employed to form classes at the same hierarchical level. In an analysis of citation orders many examples were found that conform to the principles followed in library classifications, but a number of inconsistencies in this regard were also noted

    Abstract
    Three pre-web articles about using hypertext for knowledge representation. Duncan discusses how to use graphical, hypertext displays (she used Xerox PARC's NoteCards on a Xerox 1186 workstation) along with concept maps and facet analysis, a combination that would now be done with topic maps. The screen shots of her graphical displays are quite interesting. Her interest in facets is in how to use them to show things to different people in different ways, for example, so that experts can enter knowledge into a system in one way while novices can see it in another. Duncan found that facet labels (e.g. Process and Product) prompted the expert to think of related concepts when inputting data, and made navigation easier for users. Facets can be joined together, e.g. "Agents (causing) Process," leading to a "reasoning system." She is especially interested in how to show relstionships between two things: e.g., A causes B, A uses B, A occurs in B. This is an important question in facet theory, but probably not worth worrying about in a small online classification where the relations are fixed and obvious. These articles may be difficult to find, in which case the reader can find a nice sumary in the next article, by Ellis and Vasconcelos (2000). Anyone interested in tracing the history of facets and hypertext will, however, want to see the originals.

    Abstract
    In a large-scale classification system, such as UDC, users are often troubled during the process of finding a relevant classification number for his concept or term and producing (combining) a final compound classification number. UDC tables are now computerized in many language editions, and the MRF had released as a master file (database) by the UDCC in 1993. In this paper, a system function is described for a man-machine interactive system to support compound UDC number assignment, and the necessary re-organization of UDC data/file formats are considered for the use in the automatic classification number combination

    Abstract
    Argues that classification systems have an important role to play in knowledge organization in the new world electronic order. The natural language approach is not incompatible with the use of a classification system and classification has untapped potential as a multilingual switching language. Librarians must learn to present classification systems in a language understood by a general audience and promote them as general knowledge organization tools

    Abstract
    This paper examines issues relating to the use of the Dewey Decimal Classification (DDC) in a future development of view-based searching to Online Public Access Catalogues (OPAC). View-based searching systems, exercising the principles of fully faceted classification techniques for both bibliographic and corporate database retrieval applications, are now being applied to utilise Dewey concept hierarchies in a University OPAC. Issues of efficiency and effectiveness in the evolving organisation and classification of information within libraries are examined to explain why fully faceted classification schemes have yet to realise their full potential in libraries. The key to their application in OPACs lies in the use of faceted classification as pre-coordinated indexing and abandoning the single dimension relative ordering of books on shelves. The need to maintain a single relative physical position on a bookshelf is the major source of complexity in classification. Extensive latent benefits will be realised when systematic subject arrangements, providing alternative views onto OPACs, are coupled to view-based browser and search techniques. Time and effort will be saved, and effectiveness increased, as rapid access is provided to the most appropriate information to satisfy the needs of the user. A future for Dewey Classification divorced from its decimal notation is anticipated
