Abstract

ANALYTICO-SYNTHETIC CLASSIFICATION- the brain-child of S.R. Ranganathan has brought about an intellectual revolution in the theory and methodology of library classification by generating new ideas. By his vast erudition and deeper research in the Universe of Subjects, Ranganathan applied a postulation approach to classification based on the concept of facet analysis, Phase Analysis, Sector Analysis and Zone Analysis. His enquiry into the concept of fundamental Categories as well as the Analytico-Synthetic quality associated with it, the use of different connecting symbols as in the Meccano apparatus for constructing expressive class numbers for subjects of any depth, the versality of Notation, the analysis of Rounds and Levels, the formation and sharpening of Isolates through various devices, the introduction of the novel concepts of Specals, Systems, Speciators, and Environment Constituents has systematized the whole study of classification into principles, rules and canons. These new methodologies in classification invented as a part of Colon Classification have not only lifted practical classification form mere guess work to scientific methodology but also form an important theme in international conferences. The present work discusses in details the unique methodologies of Ranganathan as used in CC-7. The concepts of Primary Basic Subjects and Non -Primary Basic Subjects have also been discussed at length.

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

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

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

Discusses classification as a central resource of human informational activity and as a central aspect of research for many sciences. Argues that thinking about the background of classification can help improve, or at least clarify, the practical tasks of documentary workers and librarians. Discusses the relationship and gaps between cognitive science and information science, and considers the contributions of epistemology and cognitive psychology; in particular, focuses on the role of the latter in the development of an integrative theory of classification

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

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

Explains knowledge organization from an interdisciplinary perspective considering the capacity of humans to order, classify and organise. Considers classification by selective and relational criteria as positive for information retrieval. Discusses the descriptive and reductionist concepts of document classification. Proposes a concept based on the observation of the analytical and synthetic intellectual process of indexing and classifying and a unique definition for all types of information centres and documentary languages

Abstract

The purpose of this paper is to define what is meant by facet analysis, and to review briefly the history of facet analysis within the context of other types of subject analysis in libraries and within the context of information retrieval research

Abstract

Considers classification in the context of the information retrieval chain, a communication process. Defines classification as an heuristic methodology, which is being improved through scientific methodology. It is also an indexing process, setting each document in a systematic order, in a predictable place and therefore able to be efficiently retrieved. Classification appears to be determined by 4 factors: the structure of the world of documents, a function of the world of knowledge; the classification tools that allow us to codify them; the way in which people create and use classifications; and the features of the information unit

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.

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

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

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.
