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.

Wissensrepr sentation 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 erm glicht die Gestaltung von Informationsarchitekturen, die - auf der Grundlage von Begriffen und Begriffsordnungen arbeitend - gestatten, Wissen in seinen Bedeutungszusammenh ngen darzustellen. Ohne elaborierte Techniken der Wissensrepr sentation ist es unm glich, das "semantische Web" zu gestalten. Das Lehrbuch vermittelt Kenntnisse ber Metadaten und beschreibt eingehend sowohl dokumentarische wie bibliothekarische Ans tze der Inhaltserschlie ung (Thesauri und Klassifikationssysteme), Bem hungen 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. Das Buch richtet sich an Studierende der Informationswissenschaft, Informationswirtschaft und der Wirtschaftsinformatik an Hochschulen in deutschsprachigen Raum wie auch an Studierende des Bibliothekswesens. Dar ber hinaus finden auch Wissensmanager und Informationsmanager in der Unternehmenspraxis wertvolle Hinweise.
