Abstract

This paper maps the concepts "space" and "dimensionality" in classifications, in particular in visualizations hereof, from a historical perspective. After a historical excursion in the domain of classification theory of what in mathematics is known as dimensionality reduction in representations of a single universe of knowledge, its potentiality will be explored for information retrieval and navigation in the multiverse of the World Wide Web.

Abstract

Categories, or concepts of high generality representing the most basic kinds of entities in the world, have long been understood to be a fundamental element in the construction of knowledge organization systems (KOSs), particularly faceted ones. Commentators on facet analysis have tended to foreground the role of categories in the structuring of controlled vocabularies and the construction of compound index terms, and the implications of this for subject representation and information retrieval. Less attention has been paid to the variety of ways in which categories can shape the overall architectonic framework of a KOS. This case study explores the range of functions that categories took in structuring various aspects of an early analytico-synthetic KOS, Julius Otto Kaiser's method of Systematic Indexing (SI). Within SI, categories not only functioned as mechanisms to partition an index vocabulary into smaller groupings of terms and as elements in the construction of compound index terms but also served as means of defining the units of indexing, or index items, incorporated into an index; determining the organization of card index files and the articulation of the guide card system serving as a navigational aids thereto; and setting structural constraints to the establishment of cross-references between terms. In all these ways, Kaiser's system of categories contributed to the general systematicity of SI.

Abstract

In recent years, Hjørland has developed a typology of basic epistemological approaches to KO that identifies four basic positions - empiricism, rationalism, historicism/hermeneutics, and pragmatism -with which to characterize the epistemological bases and methodological orientation of KOSs. Although scholars of KO have noted that the design of a single KOS may incorporate epistemological-methodological features from more than one of these approaches, studies of concrete examples of epistemologico-methodological eclecticism have been rare. In this paper, we consider the phenomenon of epistemologico-methodological eclecticism in one theoretically significant family of KOSs - namely analytico-synthetic, or faceted, KOSs - by examining two cases - Julius Otto Kaiser's method of Systematic Indexing (SI) and Brian Vickery's method of facet analysis (FA) for document classification. We show that both of these systems combined classical features of rationalism with elements of empiricism and pragmatism and argue that such eclecticism is the norm, rather than the exception, for such KOSs in general.

Abstract

We present three fundamental, interrelated approaches to support multiple access paths to each terminal object in information hierarchies: faceted classification, faceted search, and web directories with embedded symbolic links. This survey aims to demonstrate how each approach supports users who seek information from multiple perspectives. We achieve this by exploring each approach, the relationships between these approaches, including tradeoffs, and how they can be used in concert, while focusing on a core set of hypermedia elements common to all. This approach provides a foundation from which to study, understand, and synthesize applications which employ these techniques. This survey does not aim to be comprehensive, but rather focuses on thematic issues.

Abstract

The Integrative Level Classification (ILC) research project is experimenting with a knowledge organization system based on phenomena rather than disciplines. Each phenomenon has a constant notation, which can be combined with that of any other phenomenon in a freely faceted structure. Citation order can express differential focality of the facets. Very specific subjects can have long classmarks, although their complexity is reduced by various devices. Freely faceted classification is being tested by indexing a corpus of about 3300 papers in the interdisciplinary domain of bioacoustics. The subjects of these papers often include phenomena from a wide variety of integrative levels (mechanical waves, animals, behaviour, vessels, fishing, law, ...) as well as information about the methods of study, as predicted in the León Manifesto. The archive is recorded in a MySQL database, and can be fed and searched through PHP Web interfaces. Indexer's work is made easier by mechanisms that suggest possible classes on the basis of matching title words with terms in the ILC schedules, and synthesize automatically the verbal caption corresponding to the classmark being edited. Users can search the archive by selecting and combining values in each facet. Search refinement should be improved, especially for the cases where no record, or too many records, match the faceted query. However, experience is being gained progressively, showing that freely faceted classification by phenomena, theories, and methods is feasible and successfully working.

Abstract

Acknowledging the importance of classification not only for library and information science but also for the study and mapping of the world phenomena, in this paper we revisit and systematize the main types of classifications and focus on the species of classification mainly drawing on the work of S. R. Ranganathan. We trace the evolution of library classification systems by their structures and modes of design of various shades of classification systems and make a comparative study of enumerative and faceted species of library classifications. The value of this paper is to have a picture of the whole spectrum of existing classifications, which may serve for the study of future developments and constructions of new systems. This paper updates previous works by Comaromi and Ranganathan and is also theoretically inspired by them.

Abstract

The main object of the paper is to demonstrate in detail the role of classification in information retrieval (IR) and the design of classificatory structures by the application of logical division to all forms of the content of records, subject and imaginative. The natural product of such division is a faceted classification. The latter is seen not as a particular kind of library classification but the only viable form enabling the locating and relating of information to be optimally predictable. A detailed exposition of the practical steps in facet analysis is given, drawing on the experience of the new Bliss Classification (BC2). The continued existence of the library as a highly organized information store is assumed. But, it is argued, it must acknowledge the relevance of the revolution in library classification that has taken place. It considers also how alphabetically arranged subject indexes may utilize controlled use of categorical (generically inclusive) and syntactic relations to produce similarly predictable locating and relating systems for IR.

Abstract

S.R. Ranganathan is credited with the introduction of the term "facet" in the field of knowledge organization towards the middle of the twentieth century. Facets have traditionally been used to organize document collections and to express complex subjects. In the digital world, they act as filters to facilitate navigation and improve retrieval. But the popularity of the term does not mean that a definitive characterization of the concept has been established. Indeed, several conceptualizations of the facet co-exist. This article provides an overview of formal and informal definitions found in the literature of knowledge organization, followed by a discussion of four common conceptualizations of the facet: process vs product, nature vs function, object vs subject and organization vs navigation.

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

This paper reviews Ranganathan's description of subject from mathematical angle. Ranganathan was highly influenced by Nineteenth Century mathematician George Cantor and he used the concept of infinity in developing an axiomatic interpretation of subject. Majority of library scientists interpreted the concept of subject merely as a term or descriptor or heading to include the same in cataloguing and subject indexing. Some library scientists interpreted subject on the basis of document, i.e. from the angle of the concept of aboutness or epistemological potential of the document etc. Some people explained subject from the viewpoint of social, cultural or socio-cultural process. Attempts were made to describe subject from epistemological viewpoint. But S R Ranganathan was the first to develop an axiomatic concept of subject on its own. He built up an independent idea of subject that is ubiquitously pervasive with human cognition process. To develop the basic foundation of subject, he used the mathematical concepts of infinity and infinitesimal and construed the set of subjects or universe of subjects as continuous infinite universe. The subject may also exist in extremely micro-form, which was termed as spot subject and analogized with point, which is dimensionless having only an existence. The influence of Twentieth Century physicist George Gamow on Ranganathan's thought has also been discussed.

Abstract

The identification and contextual definition of concepts is the core of knowledge organization. The full expression of comprehension is accomplished through the use of an extension device called the facet. A facet is a category of dimensional characteristics that cross the hierarchical array of concepts to provide extension, or breadth, to the contexts in which they are discovered or expressed in knowledge organization systems. The use of the facet in knowledge organization has a rich history arising in the mid-nineteenth century. As it has matured through more than a century of application, the notion of the facet in knowledge organization has taken on a variety of meanings, from that of simple categories used in web search engines to the more sophisticated idea of intersecting dimensions of knowledge. This book describes the state of the art of the understanding of facets in knowledge organization today.

Abstract

This paper focuses on the discursive formations emerging from the Social Semantic Information Spaces (SSIS) in light of the concept of emergence in the theory of integrative levels. The study aims to identify the opportunities and challenges of incorporating epistemological considerations in the act of acquiring knowledge into the consolidation of knowledge organization and mediation processes and devices in the emergence of phenomena. The goal was to analyze the effects of that concept on the actions of a sample of researchers registered in an emerging research domain in SSIS in order to understand this type of indexing done by the users and communities as a classification of integrating levels. The methodology was established by triangulation through social network analysis, consensus analysis and archaeology of knowledge. It was possible to conclude that there is a collective effort to settle a semantic interoperability model for the labeling of contents based on best practices regarding the description of the objects shared in SSIS.

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.

Abstract

Reviews the new edition of CC, which has incorporated most of the developments in the idea plane and notational plane reported in the literature during the previous 20 years, making it a 'freely faceted' scheme. However, some errors have crept in which are bound to create problems for the users. Both these aspects have been critically examined here drawing comparison, where necessary, with the previous edition of the scheme. Reveals the enormously improved capabilities of the scheme in meeting the challenge posed by the ever expanding horizon of the universe of subjects as also the inconsistencies and lack of cohesion in various schedules

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.
