- Abstract
- Indexing consists of both novel and more traditional techniques. Cutting-edge indexing techniques, such as automatic indexing, ontologies, and topic maps, were developed independently of older techniques such as thesauri, but it is now recognized that these older methods also hold expertise. Indexing describes various traditional and novel indexing techniques, giving information professionals and students of library and information sciences a broad and comprehensible introduction to indexing. This title consists of twelve chapters: an Introduction to subject readings and theasauri; Automatic indexing versus manual indexing; Techniques applied in automatic indexing of text material; Automatic indexing of images; The black art of indexing moving images; Automatic indexing of music; Taxonomies and ontologies; Metadata formats and indexing; Tagging; Topic maps; Indexing the web; and The Semantic Web.

Das Buch mit seiner Auswahl von über 150 Klassifikationen und Thesauri aus Naturwissenschaft, Technik, Wirtschaft und Patenwesen macht es zu einem brauchbaren Nachschlagewerk, zumal auch ein umfassender Index nach Sachgebieten, nach Datenbanken und nach Klassifikationen und Thesauri angeboten wird. Nach einer 13-seitigen Einführung (Kapitel 1 und 2) folgt mit dem 3. Kapitel die "Darstellung von Klassifikationen und Thesauri", im wesentlichen aus den Beschreibungen der Hersteller zusammengestellt. Hier werden Dokumentationssprachen der Fachgebiete - Naturwissenschaften (3.1) und deren Spezialisierungen wie zum Beispiel "Biowissenschaften und Biotechnologie", "Chemie" oder "Umwelt und Ökonomie", aber auch "Mathematik und Informatik" (?) auf 189 Seiten vorgestellt, - Technik mit zum Beispiel "Fachordnung Technik", "Subject Categories (INIS/ ETDE) mit 17 Seiten verhältnismäßig knapp abgehandelt, - Wirtschaft mit "Branchen-Codes", "Product-Codes", "Länder-Codes"",Fachklas-sifikationen" und "Thesauri" ausführlich auf 57 Seiten präsentiert, - Patente und Normen mit zum Beispiel "Europäische Patentklassifikation" oder "International Patent Classification" auf 33 Seiten umrissen. Jedes Teilgebiet wird mit einer kurzen Beschreibung eingeleitet. Danach folgen die jeweiligen Beschreibungen mit den Merkmalen: "Anschrift des Erstellers", "Themen-gebiet(e)", "Sprache", "Verfügbarkeit", "An-wendung" und "Ouelle(n)". "Das Buch wendet sich an alle Information Professionals, die Dokumentationssprachen aufbauen und nutzen" heißt es in der Verlagsinformation. Zwar ist es nicht notwendig, die informationswissenschaftlichen Aspekte der Klassifikationen und Thesauri abzuhandeln, aber ein Hinweis auf die Bedeutung der Information und Dokumentation und/oder der Informationswissenschaft wäre schon angebracht, um in der Welt der Informations- und Wissenswirtschaft zu demonstrieren, welchen Beitrag unsere Profession leistet. Andernfalls bleibt das Blickfeld eingeschränkt und der Anschluss an neuere Entwicklungen ausgeblendet. Dieser Anknüpfungspunkt wäre beispielsweise durch einen Exkurs über Topic Map/Semantic Web gegeben. Der Verlag liefert mit der Herausgabe die ses Kompendiums einen nützlichen ersten Baustein zu einem umfassenden Verzeichnis von Thesauri und Klassifikationen."

- Abstract
- Thesauri are Knowledge Organization Systems (KOS), that arise from the consensus of wide communities. They have been in use for many years and are regularly updated. Whereas in the past thesauri were designed for information professionals for indexing and searching, today there is a demand for conceptual vocabularies that enable inferencing by machines. The development of the Semantic Web has brought a new opportunity for thesauri, but thesauri also face the challenge of proving that they add value to it. The evolution of thesauri toward their integration with the Semantic Web is examined. Elements and structures in the thesaurus standard, ISO 25964, and SKOS (Simple Knowledge Organization System), the Semantic Web standard for representing KOS, are reviewed and compared. Moreover, the integrity rules of thesauri are contrasted with the axioms of SKOS. How SKOS has been applied to represent some real thesauri is taken into account. Three thesauri are chosen for this aim: AGROVOC, EuroVoc and the UNESCO Thesaurus. Based on the results of this comparison and analysis, the benefits that Semantic Web technologies offer to thesauri, how thesauri can contribute to the Semantic Web, and the challenges that would help to improve their integration with the Semantic Web are discussed.

- Abstract
- The World Wide Web and the use of HTML-based information displays has greatly increased access to online information sources, but at the same time limits the ways in which they can be used. By the same token, Web-based indexing and search engines give us access to the full text of online documents, but make it difficult to access them in any kind of organized, systematic way. For years before the advent of the Internet, lexicographers built weIl-structured subject thesauri to organize large collections of documents. These have since been converted into electronic form and even put online, but in ways that are largely uncoordinated and not useful for searching. This paper describes some of the ways in which XML-based Web services could be used to coordinate subject thesauri and other online vocabulary sources to create a "Thesauro-Web" that could be used by both searchers and indexers to improve subject access an the Internet.

- Abstract
- This article provides an overview of recent developments relating to the application of thesauri in information organisation and retrieval on the World Wide Web. It describes some recent thesaurus projects undertaken to facilitate resource description and discovery and access to wide-ranging information resources on the Internet. Types of thesauri available on the Web, thesauri integrated in databases and information retrieval systems, and multiple-thesaurus systems for cross-database searching are also discussed. Collective efforts and events in addressing the standardisation and novel applications of thesauri are briefly reviewed.

- Abstract
- This document describes in brief how to express the content and structure of a thesaurus, and metadata about a thesaurus, in RDF. Using RDF allows data to be linked to and/or merged with other RDF data by semantic web applications. The Semantic Web, which is based on the Resource Description Framework (RDF), provides a common framework that allows data to be shared and reused across application, enterprise, and community boundaries.

- Abstract
- Ein Konferenzereignis der besonderen Art fand am 18. und 19. November 2010 in Luxemburg statt. Initiiert durch das Amt für Veröffentlichungen der Europäischen Union (http://publications.europa.eu) waren Bibliothekare und Information Professionals eingeladen, um über die Zukunft mehrsprachiger kontrollierter Vokabulare in Informationssystemen und insbesondere deren Beitrag zum Semantic Web zu diskutieren. Organisiert wurde die Konferenz durch das EuroVoc-Team, das den Thesaurus der Europäischen Union bearbeitet. Die letzte EuroVoc-Konferenz fand im Jahr 2006 statt. In der Zwischenzeit ist EuroVoc zu einem ontologie-basierten Thesaurusmanagementsystem übergegangen und hat systematisch begonnen, Semantic-Web-Technologien für die Bearbeitung und Repräsentation einzusetzen und sich mit anderen Vokabularen zu vernetzen. Ein produktiver Austausch fand mit den Produzenten anderer europäischer und internationaler Vokabulare (z.B. United Nations oder FAO) sowie Vertretern aus Projekten, die an Themen über automatische Indexierung (hier insbesondere parlamentarische und rechtliche Dokumente) sowie Interoperabilitiät zwischen Vokabularen arbeiten, statt.

- Abstract
- Thesauri can be useful resources for indexing and retrieval on the Semantic Web, but often they are not published in RDF/OWL. To convert thesauri to RDF for use in Semantic Web applications and to ensure the quality and utility of the conversion a structured method is required. Moreover, if different thesauri are to be interoperable without complicated mappings, a standard schema for thesauri is required. This paper presents a method for conversion of thesauri to the SKOS RDF/OWL schema, which is a proposal for such a standard under development by W3Cs Semantic Web Best Practices Working Group. We apply the method to three thesauri: IPSV, GTAA and MeSH. With these case studies we evaluate our method and the applicability of SKOS for representing thesauri.

- Abstract
- The task of an information architect is to create web sites where users can actually find the information they are looking for. As the ocean of information rises and leaves what we seek ever more deeply buried in what we don't seek, this discipline becomes ever more relevant. Information architecture involves many different aspects of web site creation and organization, but its principal tools are information organization techniques developed in other disciplines. Most of these techniques come from library science, such as thesauri, taxonomies, and faceted classification. Topic maps are a relative newcomer to this area and bring with them the promise of better-organized web sites, compared to what is possible with existing techniques. However, it is not generally understood how topic maps relate to the traditional techniques, and what advantages and disadvantages they have, compared to these techniques. The aim of this paper is to help build a better understanding of these issues.
