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

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

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

Computers have transformed from single isolated devices to entry points into a worldwide network of information exchange. Consequently, support in the exchange of data, information, and knowledge is becoming the key issue in computer technology today. The increasing volume of data available on the Web makes information retrieval a tedious and difficult task. Researchers are now exploring the possibility of creating a semantic web, in which meaning is made explicit, allowing machines to process and integrate web resources intelligently. The vision of the semantic web introduces the next generation of the Web by establishing a layer of machine-understandable data. The success of the semantic web depends on the easy creation, integration and use of semantic data, which will depend on web ontology. The faceted approach towards analyzing and representing knowledge given by S R Ranganathan would be useful in this regard. Ontology development in different fields is one such area where this approach given by Ranganathan could be applied. This paper presents a case of developing ontology for the field of banking.

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

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

"dwibindu vargiikaraNa" is the Kannada rendering of the revised Colon Classification, 7th Edition, intended essentially for the classification of macro documents. This paper discusses the planning, preparation, and features of Colon Classification (CC) in Kannada, one of the major Indian languages as well as the Official Language of Karnataka, and uploading the CC on the web. Linguistic issues related to the Kannada rendering are discussed with possible solutions. It creates facilities in the field of Indexing Language (IL) to prepare products such as, Subject Heading List, Information Retrieval Thesaurus, and creation of subject glossaries or updating the available subject dictionaries in Kannada.

Abstract

A modest attempt is made in this paper to show how Ranganathan's Principles for Helpful Sequence are relevant in technical writings as writers need to organise the knowledge in a helpful sequence. Instead of relying on intuition, a deliberate understanding of the Principles for Helpful Sequence as recognised by Ranganathan would be more useful in bringing out effective products. The paper first outlines the eight Principles for Helpful Sequence and then goes on to explore the relevance of each of these eight principles to a wide range of technical documents. The paper concludes that an understanding of these principles is part of the core competencies of technical writers even in the web environment.

Abstract

S R Ranganathan's ideas have influenced library classification since the inception of his Colon Classification in 1933. His address at Elsinore, "Library Classification Through a Century", was his grand vision of the century of progress in classification from 1876 to 1975, and looked to the future of faceted classification as the means to provide a cohesive system to organize the world's information. Fifty years later, the internet and its achievements, social ecology, and consequences present a far more complicated picture, with the library as he knew it as a very small part and the problems that he confronted now greatly exacerbated. The systematic nature of Ranganathan's canons, principles, postulates, and devices suggest that modern semantic algorithms could guide automatic subject tagging. The vision presented here is one of internet-wide faceted classification and retrieval, implemented as open, distributed facets providing unified faceted searching across all web sites.

Abstract

Freely faceted classifications allow for free combination of concepts across all knowledge domains, and for sorting of the resulting compound classmarks. Starting from work by the Classification Research Group, the Integrative Levels Classification (ILC) project has produced a first edition of a general freely faceted scheme. The system is managed as a MySQL database, and can be browsed through a Web interface. The ILC database structure provides a case for identifying and representing the structural elements of any freely faceted classification. These belong to both the notational and the verbal planes. Notational elements include: arrays, chains, deictics, facets, foci, place of definition of foci, examples of combinations, subclasses of a faceted class, groupings, related classes; verbal elements include: main caption, synonyms, descriptions, included terms, related terms, notes. Encoding of some of these elements in an international mark-up format like SKOS can be problematic, especially as this does not provide for faceted structures, although approximate SKOS equivalents are identified for most of them.

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

Shiyali Ramamrita Ranganathan's theory of classification spans a number of works over a number of decades. And while he was devoted to solving many problems in the practice of librarianship, and is known as the father of library science in India (Garfield, 1984), his work in classification revolves around one central concern. His classification research addressed the problems that arose from introducing new ideas into a scheme for classification, while maintaining a meaningful hierarchical and systematically arranged order of classes. This is because hierarchical and systematically arranged classes are the defining characteristic of useful classification. To lose this order is to through the addition of new classes is to introduce confusion, if not chaos, and to move toward a useless classification - or at least one that requires complete revision. In the following chapter, I outline the stages, and the elements of those stages, in Ranganathan's thought on classification from 1926-1972, as well as posthumous work that continues his agenda. And while facets figure prominently in all of these stages; but for Ranganathan to achieve his goal, he must continually add to this central feature of his theory of classification. I will close this chapter with an outline of persistent problems that represent research fronts for the field. Chief among these are what to do about scheme change and the open question about the rigor of information modeling in light of semantic web developments.
