Abstract

Colon Classification (CC) is truly the first freely faceted scheme for library classification devised and propagated by Dr. S.R. Ranganathan. The scheme is being taught in theory and practice to the students in most of the LIS schools in India and abroad also. Many manuals, Guide books and Introductory works have been published on CC in the past. But the present work tread a new path in presenting CC to the student, teaching and professional community. The present work Colon Classification: Theory and Practice; A Self Instructional Manual is the result of author's twenty-five years experience of teaching theory and practice of CC to the students of LIS. For the first ime concerted and systematic attempt has been made to present theory and practice of CC in self-instructional mode, keeping in view the requirements of students learners of Open Universities/ Distance Education Institutions in particular. The other singificant and novel features introduced in this manual are: Presenting the scope of each block consisting certain units bollowed by objectives, introduction, sections, sub-sections, self check exercises, glossary and assignment of each unit. It is hoped that all these features will help the users/readers of this manual to understand and grasp quickly, the intricacies involved in theory and practice of CC(6th Edition). The manual is presented in three blocks and twelve units.

Abstract

This entry looks at the origins of the Bliss Bibliographic Classification 2nd edition and the theory on which it is built. The reasons for the decision to revise the classification are examined, as are the influences on classification theory of the mid-twentieth century. The process of revision and construction of schedules using facet analysis is described. The use of BC2 is considered along with some recent development work on thesaural and digital formats.

Abstract

Introduction into the structure, contents and specifications (especially the Systematifier) of the Information Coding Classification, developed in the seventies and used in many ways by the author and a few others following its publication in 1982. Its theoretical basis is explained consisting in (1) the Integrative Level Theory, following an evolutionary approach of ontical areas, and integrating also on each level the aspects contained in the sequence of the levels, (2) the distinction between categories of form and categories of being, (3) the application of a feature of Systems Theory (namely the element position plan) and (4) the inclusion of a concept theory, distinguishing four kinds of relationships, originated by the kinds of characteristics (which are the elements of concepts to be derived from the statements on the properties of referents of concepts). Its special Subject Groups on each of its nine levels are outlined and the combinatory facilities at certain positions of the Systematifier are shown. Further elaboration and use have been suggested, be it only as a switching language between the six existing universal classification systems at present in use internationally.

Abstract

During the twentieth century, bibliographic classification theory underwent a structural revolution. The first modern bibliographic classifications were top-down systems that started at the universe of knowledge and subdivided that universe downward to minute subclasses. After the invention of faceted classification by S.R. Ranganathan, the ideal was to build bottom-up classifications that started with the universe of concepts and built upward to larger and larger faceted classes. This ideal has not been achieved, and the two kinds of classification systems are not mutually exclusive. This paper examines the process by which this structural revolution was accomplished by looking at the spread of facet theory after 1924 when Ranganathan attended the School of Librarianship, London, through selected classification textbooks that were published after that date. To this end, the paper examines the role of W.C.B. Sayers as a teacher and author of three editions of The Manual of Classification for Librarians and Bibliographers. Sayers influenced both Ranganathan and the various members of the Classification Research Group (CRG) who were his students. Further, the paper contrasts the methods of evaluating classification systems that arose between Sayers's Canons of Classification in 1915- 1916 and J. Mills's A Modern Outline of Library Classification in 1960 in order to demonstrate the speed with which one kind of classificatory structure was overtaken by another.

Abstract

In the early years of the 20th century, Julius Otto Kaiser (1868-1927), a special librarian and indexer of technical literature, developed a method of knowledge organization (KO) known as systematic indexing. Certain elements of the method-its stipulation that all indexing terms be divided into fundamental categories "concretes", "countries", and "processes", which are then to be synthesized into indexing "statements" formulated according to strict rules of citation order-have long been recognized as precursors to key principles of the theory of faceted classification. However, other, less well-known elements of the method may prove no less interesting to practitioners of KO. In particular, two aspects of systematic indexing seem to prefigure current trends in KO: (1) a perspectivist outlook that rejects universal classifications in favor of information organization systems customized to reflect local needs and (2) the incorporation of index terms extracted from source documents into a polyhierarchical taxonomical structure. Kaiser's perspectivism anticipates postmodern theories of KO, while his principled use of polyhierarchy to organize terms derived from the language of source documents provides a potentially fruitful model that can inform current discussions about harvesting natural-language terms, such as tags, and incorporating them into a flexibly structured controlled vocabulary.

Abstract

Integrative level classification (ILC) is a research project being developed since 2004 by some members of the Italian chapter of ISKO, also involving cooperation with other researchers. Anyone interested is welcome to contact us at: ilc@mate.unipv.it. Aim of the project is to test application of the theory of integrative levels to knowledge organization (KO). This implies a naturalistic-ontological approach to KO, which is obviously not the only possible approach - actually it even looks to be unfashionable nowadays, although it agrees with current trends towards interdisciplinarity and interrelation between many research fields.

Abstract

Facets and general categories used in bibliographic classification have been based on a disciplinary organization of knowledge. However, facets and categories of phenomena independent from disciplines can be identified similarly. Phenomena can be classified according to a series of integrative levels (layers), which in turn can be grouped into the major strata of form, matter, life, mind, society and culture, agreeing with Nicolai Hartmann's ontology. Unlike a layer, a stratum is not constituted of elements of the lower ones; rather, it represents the formal pattern of the lower ones, like the horse hoof represents the shape of the steppe. Bibliographic categories can now be seen in the light of level theory: some categories are truly general, while others only appear at a given level, being the realization of a general category in the specific context of the level: these are the facets of that level. In the notation of the Integrative Level Classification project, categories and facets are represented by digits, and displayed in a Web interface with the help of colours.

Abstract

Facet analysis is an established methodology for building classifications and subject indexing systems, but has been less rigorously applied to thesauri. The process of creating a compatible thesaurus from the schedules of the Bliss Bibliographic Classification 2nd edition highlights the ways in which the conceptual relationships in a subject field are handled in the two types of retrieval languages. An underlying uniformity of theory is established, and the way in which software can manage the relationships is discussed. The manner of displaying verbal expressions of concepts (vocabulary control) is also considered, but is found to be less well controlled in the classification than in the thesaurus. Nevertheless, there is good reason to think that facet analysis provides a sound basis for structuring a variety of knowledge organization tools.

Rez. in: KO 36(2009) no.1, S.62-63 (K. La Barre): "This special issue of Axiomathes presents an ambitious dual agenda. It attempts to highlight aspects of facet analysis (as used in LIS) that are shared by cognate approaches in philosophy, psychology, linguistics and computer science. Secondarily, the issue aims to attract others to the study and use of facet analysis. The authors represent a blend of lifetime involvement with facet analysis, such as Vickery, Broughton, Beghtol, and Dahlberg; those with well developed research agendas such as Tudhope, and Priss; and relative newcomers such as Gnoli, Cheti and Paradisi, and Slavic. Omissions are inescapable, but a more balanced issue would have resulted from inclusion of at least one researcher from the Indian school of facet theory. Another valuable addition might have been a reaction to the issue by one of the chief critics of facet analysis. Potentially useful, but absent, is a comprehensive bibliography of resources for those wishing to engage in further study, that now lie scattered throughout the issue. Several of the papers assume relative familiarity with facet analytical concepts and definitions, some of which are contested even within LIS. Gnoli's introduction (p. 127-130) traces the trajectory, extensions and new developments of this analytico- synthetic approach to subject access, while providing a laundry list of cognate approaches that are similar to facet analysis. This brief essay and the article by Priss (p. 243-255) directly addresses this first part of Gnoli's agenda. Priss provides detailed discussion of facet-like structures in computer science (p. 245- 246), and outlines the similarity between Formal Concept Analysis and facets. This comparison is equally fruitful for researchers in computer science and library and information science. By bridging into a discussion of visualization challenges for facet display, further research is also invited. Many of the remaining papers comprehensively detail the intellectual heritage of facet analysis (Beghtol; Broughton, p. 195-198; Dahlberg; Tudhope and Binding, p. 213-215; Vickery). Beghtol's (p. 131-144) examination of the origins of facet theory through the lens of the textbooks written by Ranganathan's mentor W.C.B. Sayers (1881-1960), Manual of Classification (1926, 1944, 1955) and a textbook written by Mills A Modern Outline of Classification (1964), serves to reveal the deep intellectual heritage of the changes in classification theory over time, as well as Ranganathan's own influence on and debt to Sayers.
Two of the papers revisit the interaction of facets with the theory of integrative levels, which posits that the organization of the natural world reflects increasingly interdependent complexity. This approach was tested as a basis for the creation of faceted classifications in the 1960s. These contemporary treatments of integrative levels are not discipline-driven as were the early approaches, but instead are ontological and phenomenological in focus. Dahlberg (p. 161-172) outlines the creation of the ICC (Information Coding System) and the application of the Systematifier in the generation of facets and the creation of a fully faceted classification. Gnoli (p. 177-192) proposes the use of fundamental categories as a way to redefine facets and fundamental categories in "more universal and level-independent ways" (p. 192). Given that Axiomathes has a stated focus on "contemporary issues in cognition and ontology" and the following thesis: "that real advances in contemporary science may depend upon a consideration of the origins and intellectual history of ideas at the forefront of current research," this venue seems well suited for the implementation of the stated agenda, to illustrate complementary approaches and to stimulate research. As situated, this special issue may well serve as a bridge to a more interdisciplinary dialogue about facet analysis than has previously been the case."

Abstract

Purpose - The aim of this article is to estimate the impact of faceted classification and the faceted analytical method on the development of various information retrieval tools over the latter part of the twentieth and early twenty-first centuries. Design/methodology/approach - The article presents an examination of various subject access tools intended for retrieval of both print and digital materials to determine whether they exhibit features of faceted systems. Some attention is paid to use of the faceted approach as a means of structuring information on commercial web sites. The secondary and research literature is also surveyed for commentary on and evaluation of facet analysis as a basis for the building of vocabulary and conceptual tools. Findings - The study finds that faceted systems are now very common, with a major increase in their use over the last 15 years. Most LIS subject indexing tools (classifications, subject heading lists and thesauri) now demonstrate features of facet analysis to a greater or lesser degree. A faceted approach is frequently taken to the presentation of product information on commercial web sites, and there is an independent strand of theory and documentation related to this application. There is some significant research on semi-automatic indexing and retrieval (query expansion and query formulation) using facet analytical techniques. Originality/value - This article provides an overview of an important conceptual approach to information retrieval, and compares different understandings and applications of this methodology.
