Abstract

The paper takes a retrospective look at the work of Henry Evelyn Bliss, classificationist theorist and author of the Bibliographic Classification. Major features of his writings and philosophy are examined and evaluated for the originality of their contribution to the corpus of knowledge in the discipline. Reactions to Bliss's work are analysed, as is his influence on classification theory of the 20th century. Contemporary work on knowledge organization is seen to continue a number of strands from Bliss's original writings. His standing as a classificationist is compared with that of Ranganathan, with the conclusion that he is not given the credit he deserves.

Abstract

The ways in which notation can be used to express the content of documents to which it relates are various. At the most superficial level notation can correspond to the hierarchical structure of the schedules or link to literal components. The notation of compound concepts can express the structure and composition of the compound, and systems exist in which symbols denote the functional roles of the constituent elements and the relationships between them. At the highest level notation can be used to mirror the actual structure of those entities which it represents, as in the case of mathematical systems or chemical compounds. Methods of displaying these structures are examined, and the practicality in a documentary context is questioned, with particular reference to recent revision work on the chemistry class of the Bliss Bibliographic Classification 2nd edition (BC2)

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

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

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

Purpose - The purpose of this editorial is to introduce the selected Proceedings of the 1st National Conference of ISKO UK, the UK Chapter of the International Society for Knowledge Organization. It aims to provide some background for the group, and place it within the context of the recent history of information organization and retrieval in subject domains. Design/methodology/approach - The paper introduces a selection of papers delivered at the 1st National Conference of the UK Chapter of the International Society for Knowledge Organization. Findings - The field of knowledge organization is lively and progressive, and researchers and practitioners in many sectors are actively engaged with it, despite its apparent decline in LIS education. New communities of interest may use different terms to describe this work, but there is much common ground, and a growing convergence of ideas and methods. Originality/value - The value of existing theory is now more widely recognised, and the importance of structured knowledge organization systems and vocabularies in retrieval is generally acknowledged. It is to be hoped that these important areas of information practice and research will soon be restored to their former place in professional education.

Abstract

Recent revision of UDC classes has aimed at implementing a more faceted approach. Many compound classes have been removed from the main tables, and more radical revisions of classes (particularly those for Medicine and Religion) have introduced a rigorous analysis, a clearer sense of citation order, and building of compound classes according to a more logical system syntax. The faceted approach provides a means of formalizing the relationships in the classification and making them explicit for machine recognition. In the Bliss Bibliographic Classification (BC2) (which has been a source for both UDC classes mentioned above), terminologies are encoded for automatic generation of hierarchical and associative relationships. Nevertheless, difficulties are encountered in vocabulary control, and a similar phenomenon is observed in UDC. Current work has revealed differences in the vocabulary of humanities and science, notably the way in which terms in the humanities should be handled when these are semantically complex. Achieving a balance between rigour in the structure of the classification and the complexity of natural language expression remains partially unresolved at present, but provides a fertile field for further research.

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

The genesis of the Group: In 1948, as part of the post-war renewal of library services in the United Kingdom, the Royal Society organized a Conference on Scientific Information.' What, at the time, must have seemed a minute part of the grand plan, but was later to have a transforming effect on the theory of knowledge organization throughout the remainder of the century, was the setting up of a standing committee of a small group of specialists to investigate the organization and retrieval of scientific information. In 1950, the secretary of that committee, J.D. Bernal, suggested that it might be appropriate to ask a group of librarians to do a study of the problem. After a couple of years of informal discussion it was agreed, in February 1952, to form a Classification Research Group - the CRG as it has become known to subsequent generations. The Group published a brief corporate statement of its views in the Library Association Record in June 1953 and submitted a memorandum to the Library Association Research Committee in May 1955, entitled "The need for a faceted classification as the basis of all methods of information retrieval". This memorandum was published in the proceedings of what has become known as the "Dorking Conference" in 1957. Of the original fifteen members, four still belong to the Group, three of whom are in regular attendance: Eric Coates, Douglas Foskett and Jack Mills. Brian Vickery ceased attending regularly in the 1960s but has retained his interest in their doings: he was present at the 150th celebratory meeting in 1984 and played an active part in the "Dorking revisited" conference held in 1997. The stated aim of the Group was 'To review the basic principles of bibliographic classification, unhampered by allegiance to any particular published scheme' and it can truly be stated that the work of its members has had a fundamental influence on the teaching and practice of information retrieval. It is paradoxical that this collection of people has exerted such a strong theoretical sway because their aims were from the outset and remain essentially practical. This fact is sometimes overlooked in the literature on knowledge organization: there is a tendency to get carried away, and for researchers of today to concentrate so hard on what might be that they overlook what is needed, useful and practical - the entire objective of any retrieval system.

Trickey): "Vanda has provided a very useful work that will enable any reader who is prepared to follow her instruction to produce a thesaurus that will be a quality language-based subject access tool that will make the task of information retrieval easier and more effective. Once again I express my gratitude to Vanda for producing another excellent book." - Electronic Library 24(2006) no.6, S.866-867 (A.G. Smith): "Essential thesaurus construction is an ideal instructional text, with clear bullet point summaries at the ends of sections, and relevant and up to date references, putting thesauri in context with the general theory of information retrieval. But it will also be a valuable reference for any information professional developing or using a controlled vocabulary." - KO 33(2006) no.4, S.215-216 (M.P. Satija)

Rez. in: KO 32(2005) no.1, S.47-49 (M. Hudon): "Vanda Broughton's Essential Classification is the most recent addition to a very small set of classification textbooks published over the past few years. The book's 21 chapters are based very closely an the cataloguing and classification module at the School of Library, Archive, and Information studies at University College, London. The author's main objective is clear: this is "first and foremost a book about how to classify. The emphasis throughout is an the activity of classification rather than the theory, the practical problems of the organization of collections, and the needs of the users" (p. 1). This is not a theoretical work, but a basic course in classification and classification scheme application. For this reviewer, who also teaches "Classification 101," this is also a fascinating peek into how a colleague organizes content and structures her course. "Classification is everywhere" (p. 1): the first sentence of this book is also one of the first statements in my own course, and Professor Broughton's metaphors - the supermarket, canned peas, flowers, etc. - are those that are used by our colleagues around the world. The combination of tone, writing style and content display are reader-friendly; they are in fact what make this book remarkable and what distinguishes it from more "formal" textbooks, such as The Organization of Information, the superb text written and recently updated (2004) by Professor Arlene Taylor (2nd ed. Westport, Conn.: Libraries Unlimited, 2004). Reading Essential Classification, at times, feels like being in a classroom, facing a teacher who assures you that "you don't need to worry about this at this stage" (p. 104), and reassures you that, although you now speed a long time looking for things, "you will soon speed up when you get to know the scheme better" (p. 137). This teacher uses redundancy in a productive fashion, and she is not afraid to express her own opinions ("I think that if these concepts are helpful they may be used" (p. 245); "It's annoying that LCC doesn't provide clearer instructions, but if you keep your head and take them one step at a time [i.e. the tables] they're fairly straightforward" (p. 174)). Chapters 1 to 7 present the essential theoretical concepts relating to knowledge organization and to bibliographic classification. The author is adept at making and explaining distinctions: known-item retrieval versus subject retrieval, personal versus public/shared/official classification systems, scientific versus folk classification systems, object versus aspect classification systems, semantic versus syntactic relationships, and so on. Chapters 8 and 9 discuss the practice of classification, through content analysis and subject description. A short discussion of difficult subjects, namely the treatment of unique concepts (persons, places, etc.) as subjects seems a little advanced for a beginners' class.
