    Abstract
    All classifications are based on ideologies and Dewey is marked by its author's origins in 19th century North America. Subsequent revisions indicate changed ways of understanding the world. Section 157 (psycho-pathology) is now included with 616.89 (mental troubles), reflecting the move to a genetic-based approach. Table 5 (racial, ethnic and national groups) is however unchanged, despite changing views on such categorisation

    Abstract
    Reports results of a comparative study of 3 classification schemes: LCC, DDC and NLM Classification to determine their effectiveness in classifying materials on health insurance. Examined 2 hypotheses: that there would be no differences in the scatter of the 3 classification schemes; and that there would be overlap between all 3 schemes but no difference in the classes into which the subject was placed. There was subject scatter in all 3 classification schemes and litlle overlap between the 3 systems

    Abstract
    A fascinating, broad-ranging article about classification, knowledge, and how they relate. Hierarchies, trees, paradigms (a two-dimensional classification that can look something like a spreadsheet), and facets are covered, with descriptions of how they work and how they can be used for knowledge discovery and creation. Kwasnick outlines how to make a faceted classification: choose facets, develop facets, analyze entities using the facets, and make a citation order. Facets are useful for many reasons: they do not require complete knowledge of the entire body of material; they are hospitable, flexible, and expressive; they do not require a rigid background theory; they can mix theoretical structures and models; and they allow users to view things from many perspectives. Facets do have faults: it can be hard to pick the right ones; it is hard to show relations between them; and it is difficult to visualize them. The coverage of the other methods is equally thorough and there is much to consider for anyone putting a classification on the web.

    Abstract
    For my segment of this program I'd like to focus on some basic qualities of classification schemes. These qualities are critical to our ability to truly organize knowledge for access. As I see it, there are at least five qualities of note. The first one of these properties that I want to talk about is "authoritative." By this I mean standardized, but I mean more than standardized with a built in consensus-building process. A classification scheme constructed by a collaborative, consensus-building process carries the approval, and the authority, of the discipline groups that contribute to it and that it affects... The next property of classification systems is "expandable," living, responsive, with a clear locus of responsibility for its continuous upkeep. The worst thing you can do with a thesaurus, or a classification scheme, is to finish it. You can't ever finish it because it reflects ongoing intellectual activity... The third property is "intuitive." That is, the system has to be approachable, it has to be transparent, or at least capable of being transparent. It has to have an underlying logic that supports the classification scheme but doesn't dominate it... The fourth property is "organized and logical." I advocate very strongly, and agree with Lois Chan, that classification must be based on a rule-based structure, on somebody's world-view of the syndetic structure... The fifth property is "universal" by which I mean the classification scheme needs be useable by any specific system or application, and be available as a language for multiple purposes.

    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
    Intended is first of all a preliminary review of the implications that the new approaches to the theory of classification, mainly from cognitive psychology and epistemology may have for information work and research. As a secondary topic the scientific relations existing among information science, epistemology and the cognitive sciences are discussed. Classification is seen as a central activity in all daily and scientific activities, and, of course, of knowledge organization in information services. There is a mutual implication between classification and conceptualization, as the former moves in a natural way to the latter and the best result elaborated for classification is the concept. Research in concept theory is a need for a theory of classification. In this direction it is of outstanding importance to integrate the achievements of 'natural concept formation theory' (NCFT) as an alternative approach to conceptualization different from the traditional one of logicians and problem solving researchers. In conclusion both approaches are seen as being complementary: the NCFT approach being closer to the user and the logical one being more suitable for experts, including 'expert systems'

    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

    Abstract
    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.

    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.
