Abstract

"Clearly details the conceptual and practical notions of controlled vocabularies. . provides a crash course for newcomers and offers experienced practitioners a common frame of reference. A valuable book." - Christine Connors, TriviumRLG LLC The Accidental Taxonomist is the most comprehensive guide available to the art and science of building information taxonomies. Heather Hedden-one of today's leading writers, instructors, and consultants on indexing and taxonomy topics-walks readers through the process, displaying her trademark ability to present highly technical information in straightforward, comprehensible English. Drawing on numerous real-world examples, Hedden explains how to create terms and relationships, select taxonomy management software, design taxonomies for human versus automated indexing, manage enterprise taxonomy projects, and adapt taxonomies to various user interfaces. The result is a practical and essential guide for information professionals who need to effectively create or manage taxonomies, controlled vocabularies, and thesauri. "A wealth of descriptive reference content is balanced with expert guidance. . Open The Accidental Taxonomist to begin the learning process or to refresh your understanding of the depth and breadth of this demanding discipline." - Lynda Moulton, Principal Consultant, LWM Technology Services "From the novice taxonomist to the experienced professional, all will find helpful, practical advice in The Accidental Taxonomist." - Trish Yancey, TCOO, Synaptica, LLC "This book squarely addresses the growing demand for and interest in taxonomy. ...Hedden brings a variety of background experience, including not only taxonomy construction but also abstracting and content categorization and creating back-of-the-book indexes. These experiences serve her well by building a broad perspective on the similarities as well as real differences between often overlapping types of work." - Marjorie M. K. Hlava, President and Chairman, Access Innovations, Inc., and Chair, SLA Taxonomy Division

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.

In den stärker ins Detail gehenden Kapiteln weist Broughton zunächst auf die Bedeutung des systematischen Teils eines Thesaurus neben dem alphabetischen Teil hin und erläutert dann die Elemente des letzteren, wobei neben den gängigen Thesaurusrelationen auch die Option der Ausstattung der Einträge mit Notationen eines Klassifikationssystems erwähnt wird. Die Thesaurusrelationen selbst werden später noch in einem weiteren Kapitel ausführlicher diskutiert, wobei etwa auch die polyhierarchische Beziehung thematisiert wird. Zwei Kapitel zur Vokabularkontrolle führen in Aspekte wie Behandlung von Synonymen, Vermeidung von Mehrdeutigkeit, Wahl der bevorzugten Terme sowie die Formen von Thesauruseinträgen ein (grammatische Form, Schreibweise, Zeichenvorrat, Singular/Plural, Komposita bzw. deren Zerlegung usw.). Insgesamt acht Kapitel - in der Abfolge mit den bisher erwähnten Abschnitten didaktisch geschickt vermischt - stehen unter dem Motto "Building a thesaurus". Kurz zusammengefasst, geht es dabei um folgende Tätigkeiten und Prozesse: - Sammlung des Vokabulars unter Nutzung entsprechender Quellen; - Termextraktion aus den Titeln von Dokumenten und Probleme hiebei; - Analyse des Vokabulars (Facettenmethode); - Einbau einer internen Struktur (Facetten und Sub-Facetten, Anordnung der Terme); - Erstellung einer hierarchischen Struktur und deren Repräsentation; - Zusammengesetzte Themen bzw. Begriffe (Facettenanordnung: filing order vs. citation order); - Konvertierung der taxonomischen Anordnung in ein alphabetisches Format (Auswahl der Vorzugsbegriffe, Identifizieren hierarchischer Beziehungen, verwandter Begriffe usw.); - Erzeugen der endgültigen Thesaurus-Einträge.
Weitere Rez. in: New Library World 108(2007) nos.3/4, S.190-191 (K.V. 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)
