- 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
- 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
- Vanda, lecturer at SLAIS and ISKOUK Chairperson, provided an account of the origins of faceted classification in the work of the eminent Indian scholar and librarian S. R. Ranganathan in the 1930s and described how its influence persists today. Ranganathan himself derived inspiration for his Colon Classification from Meccano, which he came across in a London toy shop whilst studying at UCL in 1924. Vanda, on the other hand, proposed that the molecular model is perhaps a better representation

- 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
- Knowledge space is diverse and thus extremely complex. With increased means for online publishing and communication world communities are actively contributing content. This augments the need to find and access resources in different contexts and for different purposes. Owing to different socio-cultural backgrounds, purposes and applications, knowledge generated by people is marked by diversity. Hence, knowledge representation for building diversity-aware tools presents interesting research challenges. In this paper, we provide an analytico-synthetic approach for dealing with topical diversity following a faceted subject indexing method. Illustrations are used to demonstrate facet analysis and synthesis for use in annotations for Media Content Analysis within the European Commission (EC) funded 'Living Knowledge' project.

- 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.

- Content
- The paper describes current work on the generation of a thesaurus format from the schedules of the Bliss Bibliographic Classification 2nd edition (BC2). The practical problems that occur in moving from a concept based approach to a terminological approach cluster around issues of vocabulary control that are not fully addressed in a systematic structure. These difficulties can be exacerbated within domains in the humanities because large numbers of culture specific terms may need to be accommodated in any thesaurus. The ways in which these problems can be resolved within the context of a semi-automated approach to the thesaurus generation have consequences for the management of classification data in the source vocabulary. The way in which the vocabulary is marked up for the purpose of machine manipulation is described, and some of the implications for editorial policy are discussed and examples given. The value of the classification notation as a language independent representation and mapping tool should not be sacrificed in such an exercise.

- 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
- Faceted analytical theory is a widely accepted approach for constructing modern classification schemes and other controlled vocabularies. While the advantages of faceted approach are broadly accepted and understood the actual implementation is coupled with many challenges when it comes to data modelling, management and retrieval. UDC Seminar 2017 revisits faceted analytical theory as one of the most influential methodologies in the development of knowledge organization systems.

- 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
- 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
- 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.
