    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
    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).

    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
    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
    Dagobert Soergel opened the discussion by saying, "Users need our help to find and make sense of information." He said that he believes that classification can provide much of the support users need. He sees little distinction between the concept of a thesaurus and that of classification since both seek to provide structure for knowledge bases in order to facilitate information retrieval. Soergel's discussion of his concept of a multifunctional, multilingual thesaurus comprised the bulk of his presentation. This thesaurus would be a database of concepts, terms, and relationships which would include classification. In this context, classification has a much broader set of functions than it currently does in most American libraries where classification serves primarily as a method of shelf arrangement. The thesaurus Soergel envisions would lay out the semantic map of a field and could therefore be used as a learning tool or as a basis for research planning, or to assist users in clarifying terms and concepts. It could support indexing and searching and provide for the organization of knowledge for expert systems and other artificial intelligence applications. Among its other features, such a thesaurus could assist users in making sense of information by providing structured presentation of search results based on user needs and preferences, and it could enhance natural language processing capabilities such as automated indexing and abstracting and machine translation.
