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.

Wissensreprasentation ist die Wissenschaft, Technik und Anwendung von Methoden und Werkzeugen, Wissen derart abzubilden, damit dieses in digitalen Datenbanken optimal gesucht und gefunden werden kann. Sie ermoglicht die Gestaltung von Informationsarchitekturen, die auf der Grundlage von Begriffen und Begriffsordnungen arbeitend gestatten, Wissen in seinen Bedeutungszusammenhangen darzustellen. Ohne elaborierte Techniken der Wissensreprasentation ist es unmoglich, das "semantische Web" zu gestalten. Das Lehrbuch vermittelt Kenntnisse uber Metadaten und beschreibt eingehend sowohl dokumentarische wie bibliothekarische Ansatze der Inhaltserschliessung (Thesauri und Klassifikationssysteme), Bemuhungen der Informatik um Begriffsordnungen (Ontologien) als auch nutzerkonzentrierte Entwicklungen im Web 2.0 (Folksonomies). Es geht um das Auswerten und Bereitstellen von Informationen bei Diensten im World Wide Web, bei unternehmensinternen Informationsdiensten im Kontext des betrieblichen Wissensmanagement sowie bei fachspezifischen professionellen (kommerziellen) Datenbanken."

From its first edition the purpose of Walford has been to identify and evaluate the widest possible range of reference materials. No rigid definition of reference is applied. In addition to the expected bibliographies, indexes, dictionaries, encyclopaedias, and directories, a number of important textbooks and manuals of general practice are included. While the majority of the items are books, Walford is a guide to reference material. Thus periodical articles, microforms, online and CD-ROM sources are all represented. In this volume a particular effort has been made to improve coverage of the latter two categories.
