Abstract

Research history of the last 70 years highlights various systems for contents assessment and retrieval of scientific literature, such as universal classifications, thesauri, ontologies etc., which have followed developments of their own, notwithstanding a general trend towards interoperability, i.e. either to become instruments for cooperation or to widen their scope to encompass neighbouring fields within their framework. In the case of thesauri and ontologies, the endeavour to upgrade them into a universal system was bound to miscarry. This paper purports to indicate ways to gain from past experience and possibly rally material achievements while updating and promoting the ontologically-based faceted Information Coding Classification as a progressive universal system fit for meeting whatever requirements in the fields of information and science at large.

Abstract

General concepts are all those form-categorial concepts which - attached to a specific concept of a classification system or thesaurus - can help to widen, sometimes even in a syntactical sense, the understanding of a case. In some existing universal classification systems such concepts have been named "auxiliaries" or "common isolates" as in the Colon Classification (CC). However, by such auxiliaries, different kinds of such concepts are listed, e.g. concepts of space and time, concepts of races and languages and concepts of kinds of documents, next to them also concepts of kinds of general activities, properties, persons, and institutions. Such latter kinds form part of the nine aspects ruling the facets in the Information Coding Classification (ICC) through the principle of using a Systematiser for the subdivision of subject groups and fields. Based on this principle and using and extending existing systems of such concepts, e.g. which A. Diemer had presented to the German Thesaurus Committee as well as those found in the UDC, in CC and attached to the Subject Heading System of the German National Library, a faceted classification is proposed for critical assessment, necessary improvement and possible later use in classification systems and thesauri.

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 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

In this paper, we propose a part of the methodological work to accompanying the development of a new type of Knowledge Organization System (KOS) based on faceted classification. Our approach to faceted classification differs from its traditional use. We develop a theoretical typology of professional documents based on their uses. Then we correlate these types of documents to specific types of KOS according to their degree of structural constraint and activities they aim to serve.

Abstract

Colon Classification (CC), based on dynamic theory of classification saw seven editions from 1928 to 1987. Libraries practising it continued with extensions and additions carried out to meet their needs since it was not revised for long after the 7th edition. Revision requires adding terms in different disciplines, organising them in relation to each other and assigning notation for shelf classification. Use of ICT would help in reviving CC and is essential for regular revision of a classification scheme. The paper explores the possibility for creation of an expert system through the design of Web based Colon Classification. The author explores the possibility by designing a prototype for online revision of Colon Classification in the paper.

Abstract

S R Ranganathan and Melvil Dewey devised two types of classification schemes viz., faceted and enumerative. Ranganathan's faceted classification scheme is based on postulates, principles and canons. It has a strong theory. While working with the two schemes, similarities are observed. This paper tries to identify and present some relationships.

Abstract

Facet analysis is proposed as a general theory of knowledge organization, with an associated methodology that may be applied to the development of terminology tools in a variety of contexts and formats. Faceted classifications originated as a means of representing complexity in semantic content that facilitates logical organization and effective retrieval in a physical environment. This is achieved through meticulous analysis of concepts, their structural and functional status (based on fundamental categories), and their inter-relationships. These features provide an excellent basis for the general conceptual modelling of domains, and for the generation of KOS other than systematic classifications. This is demonstrated by the adoption of a faceted approach to many web search and visualization tools, and by the emergence of a facet based methodology for the construction of thesauri. Current work on the Bliss Bibliographic Classification (Second Edition) is investigating the ways in which the full complexity of faceted structures may be represented through encoded data, capable of generating intellectually and mechanically compatible forms of indexing tools from a single source. It is suggested that a number of research questions relating to the Semantic Web could be tackled through the medium of facet analysis.

Abstract

Faceted classification is based on the core ideas that there are kinds or categories of concepts, and that compound, or non-elemental, concepts, which are ubiquitous in classification and subject annotation, are to be identified as being constructions of concepts of the different kinds. The categories of concepts are facets, and the individual concepts, which are instances of those facets, are foci. Usually, there are constraints on how the foci can be combined into the compound concepts. What is standard is that any combination of foci is permitted from kind-to-kind across facets, but that the foci within a facet are restricted in their use by virtue of being dependent on each other, either by being exclusive of each other or by bearing some kind of hierarchical relationship to each other. Thus faceted classification is typically considered to be a synthetic classification consisting of orthogonal facets which themselves are composed individually either of exclusive foci or of a hierarchy of foci. This paper addresses in particular this second exclusive-or-hierarchical foci condition. It evaluates the arguments for the condition and finds them not conclusive. It suggests that wider synthetic constructions should be allowed on foci within a facet.

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

Classification is the basis of knowledge organization. Ontology, a comparatively new concept used as a tool for knowledge organization, establishes connections between terms and concepts enhancing the scope and usefulness of library classification. Ranganathan had invented the strong theory of the analytico-synthetic method in classification and devised Colon Classification. In this study a domain ontology on library and information science has been developed by implementing Raganathan's faceted approach of classification. The hierarchical relationships among terms have been established primarily keeping conformity with that of Ranganathan's Colon Classification (7th edition). But to accommodate new vocabularies, DDC 23rd edition and UDC Standard edition are consulted. The Protégé ontology editor has been used. The study carefully examines the steps in which the analytico-synthetic method have been followed. Ranganathan's Canon of Characteristics and its relevant Canons have been followed for defining the class-subclass hierarchy. It concludes by identifying the drawbacks as well as the merits faced while developing the ontology. This paper proves the relevance and importance of Ranganathan's philosophy in developing ontology based knowledge organization.
