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 relations 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 The wider environment. Readership: Although primarily aimed at the practising information professional, the book is also suitable for students of library and information science.
The fourth edition of this standard student text, Organizing Knowledge, incorporates extensive revisions reflecting the increasing shift towards a networked and digital information environment, and its impact on documents, information, knowledge, users and managers. This is a key introductory text for undergraduate and postgraduate students of information management.
Dealing with information is one of the vital skills in the 21st century. It takes a fair degree of information savvy to create, represent and supply information as well as to search for and retrieve relevant knowledge. How does information (documents, pieces of knowledge) have to be organized in order to be retrievable? What role does metadata play? What are search engines on the Web, or in corporate intranets, and how do they work? How must one deal with natural language processing and tools of knowledge organization, such as thesauri, classification systems, and ontologies? How useful is social tagging? How valuable are intellectually created abstracts and automatically prepared extracts? Which empirical methods allow for user research and which for the evaluation of information systems? This Handbook is a basic work of information science, providing a comprehensive overview of the current state of information retrieval and knowledge representation. It addresses readers from all professions and scientific disciplines, but particularly scholars, practitioners and students of Information Science, Library Science, Computer Science, Information Management, and Knowledge Management. This Handbook is a suitable reference work for Public and Academic Libraries.
Library of Congress Subject Headings (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 Library of Congress Subject Headings (LCSH). Paraprofessionals who undertake cataloguing are similarly unlikely to have enjoyed an induction to the broad principles of LCSH. This is the first compact guide to LCSH written from a UK viewpoint. Key topics include: • 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 • LCSH in the online environment. Readership: 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.
A practical guide to the construction of thesauri for use in information retrieval, written by leading experts in the field. Includes: planning and design; vocabulary control; specificity and compound terms; structure and relationships; auxiliary retrieval devices; multilingual thesauri; AAT Compound Term Rules. The US ANSI/NISO Z39.19 Thesaurus construction standard is also covered.
Classification is a crucial skill for all information workers involved in organizing collections. This new edition offers fully revised and updated guidance on how to go about classifying a document from scratch. Essential Classification leads the novice classifier step by step through the basics of subject cataloguing, with an emphasis on 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 reader 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. Fully updated to reflect changes to the major general schemes (Library of Congress, LCSH, Dewey and UDC) since the first edition, and with new chapters on working with informal classification, from folksonomies to tagging and social media, this new edition will set cataloguers on the right path. Key areas covered are: - The need for classification - The variety of classification - The structure of classification - Working with informal classification - Management aspects of classification - Classification in digital space. This guide is essential reading for library school students, novice cataloguers and all information workers who need to classify but have not formally been taught how. It also offers practical guidance to computer scientists, internet and intranet managers, and all others concerned with the design and maintenance of subject tools.
Facet analysis is an important theory in the fields ofknowledge organization and information retrieval. It has been stated that 'ithas dominated what has been termed "modern classification theory"', and theClassification Research Group of the UK aimed to make it 'the basis of allinformation retrieval'. Yet the philosophical and methodological bases of facetanalysis are poorly understood by the wider information community and thetheory is not well documented. Facet Analysis provides a general overview of facet analysisas a formal methodology for building knowledge organization and search tools andas a general knowledge organization theory. The functions of faceted systems can be broadly categorized as:organizing content; building tools; designing interfaces; and empoweringsearch, and examples of all of these are discussed. Coverage includes: a full statement of the principles and theory of facetedsystems as developed by Ranganathan and the UK Classification Research Group,and that theory as it is understood today discussion of the origin and development of analytico-synthetic classification andindexing tools, and of the use of facet analytical theory to underpin designand construction discussion of different applications of facet analysis, notonly in conventional information managements contexts (classification schemesand thesauri), but also in e-environments, both academic and commercial, and onthe Web a survey of the work of a number of current writers andresearchers in the facet analytical tradition, including those who work in thedigital environment, for which a distinctive parallel strand of facet theorycan be observed. This book will be useful reading for LIS students enrolledon classification, knowledge organisation and information retrieval modules. Itwill also be of immediate use to practitioners concerned with informationorganisation, management and retrieval, as well as software engineers, webdesigners, semantic web researchers and developers.
