Abstract

The presentation will examine the potential of facet analysis as a basis for determining status and relationships of concepts in subject based tools using a controlled vocabulary, and the extent to which it can be used as a general theory of knowledge organization as opposed to a methodology for structuring classifications only.

Abstract

LCSH are increasingly seen as 'the' English language controlled vocabulary, despite their lack of a theoretical foundation, and their evident US bias. In mapping exercises between national subject heading lists, and in exercises in digital resource organization and management, LCSH are often chosen because of the lack of any other widely accepted English language standard for subject cataloguing. It is therefore important that the basic nature of LCSH, their advantages, and their limitations, are well understood both by LIS practitioners and those in the wider information community. Information professionals who attended library school before 1995 - and many more recent library school graduates - are unlikely to have had a formal introduction to LCSH. Paraprofessionals who undertake cataloguing are similarly unlikely to have enjoyed an induction to the broad principles of LCSH. There is currently no compact guide to LCSH written from a UK viewpoint, and this eminently practical text fills that gap. It features topics including: background and history of LCSH; subject heading lists; structure and display in LCSH; form of entry; application of LCSH; document analysis; main headings; topical, geographical and free-floating sub-divisions; building compound headings; name headings; headings for literature, art, music, history and law; and, LCSH in the online environment. There is a strong emphasis throughout on worked examples and practical exercises in the application of the scheme, and a full glossary of terms is supplied. No prior knowledge or experience of subject cataloguing is assumed. This is an indispensable guide to LCSH for practitioners and students alike from a well-known and popular author.

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

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.

Abstract

Classification is a crucial skill for all information workers involved in organizing collections, but it is a difficult concept to grasp - and is even more difficult to put into practice. Essential Classification offers full guidance an how to go about classifying a document from scratch. This much-needed text leads the novice classifier step by step through the basics of subject cataloguing, with an emphasis an practical document analysis and classification. It deals with fundamental questions of the purpose of classification in different situations, and the needs and expectations of end users. The novice is introduced to the ways in which document content can be assessed, and how this can best be expressed for translation into the language of specific indexing and classification systems. The characteristics of the major general schemes of classification are discussed, together with their suitability for different classification needs.

Footnote

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.
In Chapter 10, "Controlled indexing languages," Professor Broughton states that a classification scheme is truly a language "since it permits communication and the exchange of information" (p. 89), a Statement with which this reviewer wholly agrees. Chapter 11, however, "Word-based approaches to retrieval," moves us to a different field altogether, offering only a narrow view of the whole world of controlled indexing languages such as thesauri, and presenting disconnected discussions of alphabetical filing, form and structure of subject headings, modern developments in alphabetical subject indexing, etc. Chapters 12 and 13 focus an the Library of Congress Subject Headings (LCSH), without even a passing reference to existing subject headings lists in other languages (French RAMEAU, German SWK, etc.). If it is not surprising to see a section on subject headings in a book on classification, the two subjects being taught together in most library schools, the location of this section in the middle of this particular book is more difficult to understand. Chapter 14 brings the reader back to classification, for a discussion of essentials of classification scheme application. The following five chapters present in turn each one of the three major and currently used bibliographic classification schemes, in order of increasing complexity and difficulty of application. The Library of Congress Classification (LCC), the easiest to use, is covered in chapters 15 and 16. The Dewey Decimal Classification (DDC) deserves only a one-chapter treatment (Chapter 17), while the functionalities of the Universal Decimal Classification (UDC), which Professor Broughton knows extremely well, are described in chapters 18 and 19. Chapter 20 is a general discussion of faceted classification, on par with the first seven chapters for its theoretical content. Chapter 21, an interesting last chapter on managing classification, addresses down-to-earth matters such as the cost of classification, the need for re-classification, advantages and disadvantages of using print versions or e-versions of classification schemes, choice of classification scheme, general versus special scheme. But although the questions are interesting, the chapter provides only a very general overview of what appropriate answers might be. To facilitate reading and learning, summaries are strategically located at various places in the text, and always before switching to a related subject. Professor Broughton's choice of examples is always interesting, and sometimes even entertaining (see for example "Inside out: A brief history of underwear" (p. 71)). With many examples, however, and particularly those that appear in the five chapters an classification scheme applications, the novice reader would have benefited from more detailed explanations. On page 221, for example, "The history and social influence of the potato" results in this analysis of concepts: Potato - Sociology, and in the UDC class number: 635.21:316. What happened to the "history" aspect? Some examples are not very convincing: in Animals RT Reproduction and Art RT Reproduction (p. 102), the associative relationship is not appropriate as it is used to distinguish homographs and would do nothing to help either the indexer or the user at the retrieval stage.
Essential Classification is also an exercise book. Indeed, it contains a number of practical exercises and activities in every chapter, along with suggested answers. Unfortunately, the answers are too often provided without the justifications and explanations that students would no doubt demand. The author has taken great care to explain all technical terms in her text, but formal definitions are also gathered in an extensive 172-term Glossary; appropriately, these terms appear in bold type the first time they are used in the text. A short, very short, annotated bibliography of standard classification textbooks and of manuals for the use of major classification schemes is provided. A detailed 11-page index completes the set of learning aids which will be useful to an audience of students in their effort to grasp the basic concepts of the theory and the practice of document classification in a traditional environment. Essential Classification is a fine textbook. However, this reviewer deplores the fact that it presents only a very "traditional" view of classification, without much reference to newer environments such as the Internet where classification also manifests itself in various forms. In Essential Classification, books are always used as examples, and we have to take the author's word that traditional classification practices and tools can also be applied to other types of documents and elsewhere than in the traditional library. Vanda Broughton writes, for example, that "Subject headings can't be used for physical arrangement" (p. 101), but this is not entirely true. Subject headings can be used for physical arrangement of vertical files, for example, with each folder bearing a simple or complex heading which is then used for internal organization. And if it is true that subject headings cannot be reproduced an the spine of [physical] books (p. 93), the situation is certainly different an the World Wide Web where subject headings as metadata can be most useful in ordering a collection of hot links. The emphasis is also an the traditional paperbased, rather than an the electronic version of classification schemes, with excellent justifications of course. The reality is, however, that supporting organizations (LC, OCLC, etc.) are now providing great quality services online, and that updates are now available only in an electronic format and not anymore on paper. E-based versions of classification schemes could be safely ignored in a theoretical text, but they have to be described and explained in a textbook published in 2005. One last comment: Professor Broughton tends to use the same term, "classification" to represent the process (as in classification is grouping) and the tool (as in constructing a classification, using a classification, etc.). Even in the Glossary where classification is first well-defined as a process, and classification scheme as "a set of classes ...", the definition of classification scheme continues: "the classification consists of a vocabulary (...) and syntax..." (p. 296-297). Such an ambiguous use of the term classification seems unfortunate and unnecessarily confusing in an otherwise very good basic textbook an categorization of concepts and subjects, document organization and subject representation."

Abstract

The paper looks at ways in which traditional classification and indexing tools have dealt with the relationships between constituent terms; variations in these are examined and compared with the methods used in machine searching, particularly of the Internet and World Wide Web. Apparent correspondences with features of index languages are identified, and further methods of applying classification and indexing theory to machine retrieval are proposed. There are various ways in which indexing and retrieval systems, both conventional and electronic, deal with the problem of searching for documents on a subject basis, and various approaches to the analysis and processing of a query. There appear to be three basic models; the taxonomic or structural system, in which the user is offered a map of the `universe of knowledge'; the language based system, which offers a vocabulary of the subject and a grammar for dealing with compound statements; and the mathematical model using the language of symbolic logic or the algebra of set theory

Abstract

Basic skills of classification and subject indexing have been little taught in British library schools since automation was introduced into libraries. However, development of the Internet as a major medium of publication has stretched the capability of search engines to cope with retrieval. Consequently, there has been interest in applying existing systems of knowledge organization to electronic resources. Unfortunately, the classification systems have been adopted without a full understanding of modern classification principles. Analytico-synthetic schemes have been used crudely, as in the case of the Universal Decimal Classification (UDC). The fully faceted Bliss Bibliographical Classification, 2nd edition (BC2) with its potential as a tool for electronic resource retrieval is virtually unknown outside academic libraries

Content

A short discussion of using classification systems to organize the web, one of many such. The authors are both involved with BC2 and naturally think it is the best system for organizing information online. They list reasons why faceted classifications are best (e.g. no theoretical limits to specificity or exhaustivity; easier to handle complex subjects; flexible enough to accommodate different user needs) and take a brief look at how BC2 works. They conclude with a discussion of how and why it should be applied to online resources, and a plea for recognition of the importance of classification and subject analysis skills, even when full-text searching is available and databases respond instantly.

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

Many information professionals working in small units today fail to find the published tools for subject-based organization that are appropriate to their local needs, whether they are archivists, special librarians, information officers, or knowledge or content managers. Large established standards for document description and organization are too unwieldy, unnecessarily detailed, or too expensive to install and maintain. In other cases the available systems are insufficient for a specialist environment, or don't bring things together in a helpful way. A purpose built, in-house system would seem to be the answer, but too often the skills necessary to create one are lacking. This practical text examines the criteria relevant to the selection of a subject-management system, describes the characteristics of some common types of subject tool, and takes the novice step by step through the process of creating a system for a specialist environment. The methodology employed is a standard technique for the building of a thesaurus that incidentally creates a compatible classification or taxonomy, both of which may be used in a variety of ways for document or information management. Key areas covered are: What is a thesaurus? Tools for subject access and retrieval; what a thesaurus is used for? Why use a thesaurus? Examples of thesauri; the structure of a thesaurus; thesaural relationships; practical thesaurus construction; the vocabulary of the thesaurus; building the systematic structure; conversion to alphabetic format; forms of entry in the thesaurus; maintaining the thesaurus; thesaurus software; and; the wider environment. Essential for the practising information professional, this guide is also valuable for students of library and information science.

Abstract

The paper examines the development of facet analysis as a methodology and the role it plays in building classifications and other knowledge-organization tools. The use of categorical analysis in areas other than library and information science is also considered. The suitability of the faceted approach for humanities documentation is explored through a critical description of the FATKS (Facet Analytical Theory in Managing Knowledge Structure for Humanities) project carried out at University College London. This research focused on building a conceptual model for the subject of religion together with a relational database and search-and-browse interfaces that would support some degree of automatic classification. The paper concludes with a discussion of the differences between the conceptual model and the vocabulary used to populate it, and how, in the case of religion, the choice of terminology can create an apparent bias in the system.

Abstract

Broughton is one of the key people working on the second edition of the Bliss Bibliographic Classification (BC2). Her article has a brief, informative history of facets, then discusses semantic vs. syntactic relationships, standard facets used by Ranganathan and the Classification Research Group, facet analysis and citation order, and how to build subject indexes out of faceted classifications, all with occasional reference to digital environments and hypertext, but never with any specifics. It concludes by saying of faceted classification that the "capacity which it has to create highly sophisticated structures for the accommodation of complex objects suggests that it is worth investigation as an organizational tool for digital materials, and that the results of such investigation would be knowledge structures of unparalleled utility and elegance." How to build them is left to the reader, but this article provides an excellent starting point. It includes an example that shows how general concepts can be applied to a small set of documents and subjects, and how terms can be adapted to suit the material and users

Abstract

Purpose - This paper aims to provide an overview of principles and procedures involved in creating a faceted classification scheme for use in resource discovery in an online environment. Design/methodology/approach - Facet analysis provides an established rigorous methodology for the conceptual organization of a subject field, and the structuring of an associated classification or controlled vocabulary. This paper explains how that methodology was applied to the humanities in the FATKS project, where the objective was to explore the potential of facet analytical theory for creating a controlled vocabulary for the humanities, and to establish the requirements of a faceted classification appropriate to an online environment. A detailed faceted vocabulary was developed for two areas of the humanities within a broader facet framework for the whole of knowledge. Research issues included how to create a data model which made the faceted structure explicit and machine-readable and provided for its further development and use. Findings - In order to support easy facet combination in indexing, and facet searching and browsing on the interface, faceted classification requires a formalized data structure and an appropriate tool for its management. The conceptual framework of a faceted system proper can be applied satisfactorily to humanities, and fully integrated within a vocabulary management system. Research limitations/implications - The procedures described in this paper are concerned only with the structuring of the classification, and do not extend to indexing, retrieval and application issues. Practical implications - Many stakeholders in the domain of resource discovery consider developing their own classification system and supporting tools. The methods described in this paper may clarify the process of building a faceted classification and may provide some useful ideas with respect to the vocabulary maintenance tool. Originality/value - As far as the authors are aware there is no comparable research in this area.
