    Abstract
    This paper documents the continuing relevance of facet analysis as a technique for searching and organising WWW based materials. The 2 approaches underlying WWW searching and indexing - word and concept based indexing - are outlined. It is argued that facet analysis as an a posteriori approach to classification using words from the subject field as the concept terms in the classification derived represents an excellent approach to searching and organising the results of WWW searches using either search engines or search directories. Finally it is argued that the underlying philosophy of facet analysis is better suited to the disparate nature of WWW resources and searchers than the assumptions of contemporaray IR research.
    This article gives a cheerfully brief and undetailed account of how to make a faceted classification system, then describes information retrieval and searching on the web. It concludes by saying that facets would be excellent in helping users search and browse the web, but offers no real clues as to how this can be done.

    Abstract
    Stresses that S.R. Ranganathan was truly a great scholar, who made rich contribution to different aspects of library and information science, but is better known for his work in the field of library classification. discusses his distinctive contributions to classification such as normative principles, 3 plane model of work, freely faceted classification (involving facet analysis and the synthetic principle), postulational approach, fundamental categories and certain notational devices like the sector device, group notation device, emptying digit device and seminal mnemonic device. Regards these as seminal ideas forming the basis of his theory of library classification. Considers 7th ed. of the Colon Classification as the best example of the application of theses ideas

    Abstract
    Existing classification systems require constant expansion to accomodate new subject fields, while subject indexing techniques fail to display the relationship of subjects. Relational databases are currently being developed which will guide users through the differing levels of subjects, using the 'cartography of science'. Such developments will enable librarians to play a more interactive role in information retrieval and will have far-reaching consequences on the design of subject-indexing systems

    Abstract
    Comparison between grounded theory (a qualitative social science research methodology of Glaser and Strauss) and facet classification (Ranganathan)
    Content
    This article compares the qualitative method of grounded theory (GT) with Ranganathan's construction of faceted classifications (FC) in library and information science. Both struggle with a core problem-i.e., the representation of vernacular words and processes, empirically discovered, which will, although ethnographically faithful, be powerful beyond the single instance or case study. The article compares Glaser and Strauss's (1967) work with that of Ranganathan(1950).

    Abstract
    Different approaches to the classification of a knowledge field include empiristic, rationalistic, historistic, and pragmatic methods. This paper demonstrates how these different methids have been applied to the classification of psychology. An etymological apporach is insufficient to define the subject matter of psychology, because other terms can be used to describe the same domain. To define the subject matter of psychology from the point of view of its formal establishment as a science and academic discipline (in Leipzig, 1879) it is also insufficient because this was done in specific historical circumstances, which narrowed the subject matter to physiologically-related issues. When defining the subject area of a scientific field it is necessary to consider how different ontological and epistemological views have made their influences. A subject area and the approaches by which this subject area has been studied cannot be separated from each other without tracing their mutual historical interactions. The classification of a subject field is theory-laden and thus cannot be neutral or ahistorical. If classification research can claim to have a method that is more general than the study of concrete developments in the single knowledge fields the key is to be found in the general epistemological theories. It is shown how basic epistemological assumptions have formed the different approaches to psychology during the 20th century. The progress in the understanding of basic philosophical questions is decisive both for the development of a knowledge field and as the point of departure of classification. The theoretical principles developed in this paper are applied in a brief analysis of some concrete classification systems, including the one used by PsycINFO / Psychologcal Abstracts. The role of classification in modern information retrieval is also briefly discussed

    Abstract
    Is this book sociology, anthropology, or taxonomy? Sorting Things Out, by communications theorists Geoffrey C. Bowker and Susan Leigh Star, covers a lot of conceptual ground in its effort to sort out exactly how and why we classify and categorize the things and concepts we encounter day to day. But the analysis doesn't stop there; the authors go on to explore what happens to our thinking as a result of our classifications. With great insight and precise academic language, they pick apart our information systems and language structures that lie deeper than the everyday categories we use. The authors focus first on the International Classification of Diseases (ICD), a widely used scheme used by health professionals worldwide, but also look at other health information systems, racial classifications used by South Africa during apartheid, and more. Though it comes off as a bit too academic at times (by the end of the 20th century, most writers should be able to get the spelling of McDonald's restaurant right), the book has a clever charm that thoughtful readers will surely appreciate. A sly sense of humor sneaks into the writing, giving rise to the chapter title "The Kindness of Strangers," for example. After arguing that categorization is both strongly influenced by and a powerful reinforcer of ideology, it follows that revolutions (political or scientific) must change the way things are sorted in order to throw over the old system. Who knew that such simple, basic elements of thought could have such far-reaching consequences? Whether you ultimately place it with social science, linguistics, or (as the authors fear) fantasy, make sure you put Sorting Things Out in your reading pile.

    Abstract
    Presents a short review of fundamental knowledge representation methods: logical, graphical, structured and procedural notational schemes. Special attention is given to notational schemes' classifications and the characteristics on which classifications were done. Knowledge representation is one of the central problems in artificial intelligence, but a complete theory of it does not exist, and it remains a set of methods that are used, with more or less success, in attempts to solve a given problem. The characteristics of knowledge schemes play a significant role

    Abstract
    Based on the works of Aristotle, Ramon Lull, I. Kant and the experiences with relationships published in the works of S.R. Ranganathan, E.de Grolier, J. Mills, J.C. Costello, E. Wall, R. Pagès, A. Leroy, P. Braffort, M. Kervégant, J.C. Gardin and J. Farradane, categories and relationships were collected, analyzed, grouped and classified in a triadic way so that a scheme resulted by which 120 relationships could be defined and identified by their positions and their codes. The exercise was meant to create and supply a tool for the replacement of the non-significant relation symbol, the colon, in the UDC by a letter code which could express the actual relationship contained in a classificatory statement. Examples for their application illustrate different cases occuring

    A detailed examination of the UDC's history, function and future prospects. Among topics discussed are: the early pioneering work of P. Otlet and H. LaFontaine; the development of Colon Classification; the 'UDC versus switching language' debate in the 1970s; the FID standard reference code project; and the recent scheme by Williamson and McIlwaine to restructure UDC completely, converting it into a Colon Classification and also creating a thesaurus drawn from the same classification. Comments that UDC, far from being a 'prehistoric monster', is becoming a sort of test laboratory for developing new and interesting documentation structures

    Abstract
    C-KAT is a method and a tool which supports the design of feature oriented classification systems for knowlegde based systems. It uses a specialized Heuristic Classification conceptual model named 'classification by structural shift' which sees the classification process as the matching of different classifications of the same set of objects or situations organized around different structural principles. To manage the complexity induced by the cross-product, C-KAT supports the use of a leastcommittment strategy which applies in a context of constraint-directed reasoning. Presents this method using an example from the field of industrial fire insurance

    Abstract
    This article discusses some of Ranganathan's contributions to the productive, practical and theoretical aspects of classification science. These include: (1) a set of design criteria to guide the designing of schemes for knowledge / subject classification; (2) a conceptual framework for organizing the universe of subjects; and (3) an understanding of the general principles underlying subject disciplines and classificatory languages. It concludes that Ranganathan has contributed significantly to laying the foundations for a science of subject classification.

    Abstract
    This article is a selective review of recent studies in classification and indexing theory. A number of important problems are discussed, including subjectivity versus objectivity, theories of indexing, the theoretical role of automation, and theoretical approaches to a universal classification scheme. Interestingly, much of the work appears to have been done outside the United States. After reviewing the theoretical work itself, some possible reasons for the non-American origins of the work are explored

    Abstract
    Psychologists, philosophers and linguists analyse concepts and investigate their relationship to words. Concepts are also relevant to the issue of bibliographic classification, i.e. "catagorisation". Examines from a chronological point of view the various theories for the analysis and organisation of concepts ranging from the Vickery developed in 1954, to Austin's hypotheses, to Ranganathan's "fundamental categories" and the contribution made by CRG, the Classification Research Group. Illustrates other approaches to categorisation such as Farradane's (relationship between couples of concepts) and calls for a closer study of categories and concepts.
