    Abstract
    Subject based classification is an important part of information retrieval, and has a long history in libraries, where a subject taxonomy was used to determine the location of books on the shelves. We have been studying the notion of subject itself, in order to determine a formal ontology of subject for a large scale digital library card catalog system. Deep analysis reveals a lot of ambiguity regarding the usage of subjects in existing systems and terminology, and we attempt to formalize these notions into a single framework for representing it.

    Abstract
    This is a preprint to be published in the Extensions & Corrections to the UDC. The paper explains the basic functions of browsing and searching that need to be supported in relation to analytico-synthetic classifications such as Universal Decimal Classification (UDC), irrespective of any specific, real-life implementation. UDC is an example of a semi-faceted system that can be used, for instance, for both post-coordinate searching and hierarchical/facet browsing. The advantages of using a classification for IR, however, depend on the strength of the GUI, which should provide a user-friendly interface to classification browsing and searching. The power of this interface is in supporting visualisation that will 'convert' what is potentially a user-unfriendly indexing language based on symbols, to a subject presentation that is easy to understand, search and navigate. A summary of the basic functions of searching and browsing a classification that may be provided on a user-friendly interface is given and examples of classification browsing interfaces are provided.

    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
    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
    A team at the University of Michigan School of Information designed, implemented and is evaluating a WWW-based experimental system which uses classification to facilitate browsing of art images. The research team built a database of approximately 3.000 digitized images from Art History to determine if classification can be used for retrieving images from a digital database in a networked environment. A key premise in this research is that browsing can serve an important role in retrieving image information. The system was evaluated in controlled tests and through a questionnaire available to WWW users

    Abstract
    Examines ho well UDC numbers performs as a subject retrieval device in online systems. Discusses: truncation, coordination, USC as a discipline based scheme, ranges, and requirements in search software. Gives examples of UDC in pre-coordinated and post-coordinated working systems. Discusses the possible use of UDC as a thesaurus. Outlines improvements that would enable its use in online retrieval

    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
    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
    Purpose - To suggest that a theory of classification for information retrieval (IR), asked for by Spärck Jones in a 1970 paper, presupposes a full implementation of a pragmatic understanding. Part of the Journal of Documentation celebration, "60 years of the best in information research". Design/methodology/approach - Literature-based conceptual analysis, taking Sparck Jones as its starting-point. Analysis involves distinctions between "positivism" and "pragmatism" and "classical" versus Kuhnian understandings of concepts. Findings - Classification, both manual and automatic, for retrieval benefits from drawing upon a combination of qualitative and quantitative techniques, a consideration of theories of meaning, and the adding of top-down approaches to IR in which divisions of labour, domains, traditions, genres, document architectures etc. are included as analytical elements and in which specific IR algorithms are based on the examination of specific literatures. Introduces an example illustrating the consequences of a full implementation of a pragmatist understanding when handling homonyms. Practical implications - Outlines how to classify from a pragmatic-philosophical point of view. Originality/value - Provides, emphasizing a pragmatic understanding, insights of importance to classification for retrieval, both manual and automatic. - Vgl. auch: Szostak, R.: Classification, interdisciplinarity, and the study of science.

    Abstract
    A preliminary, purposive survey of definitions and current applications of facet analytical theory (FA) is used to develop a framework for the analysis of Websites. This set of guidelines may well serve to highlight commonalities and differences among FA applications an the Web. Rather than identifying FA as the terrain of a particular interest group, the goal is to explore current practices, uncover common misconceptions, extend understanding, and highlight developments that augment the traditional practice of FA and faceted classification (FC).
