    Content
    Enthält u.a. folgende Aussage von J. Aitchison u. S. Dextre Clarke: "We face a paradox. Ostensibly, the need and the opportunity to apply thesauri to information retrieval are greater than ever before. On the other hand, users resist most efforts to persuade them to apply one. The drive for interoperability of systems means we must design our vocabularies for easy integration into downstream applications such as content management systems, indexing/metatagging interfaces, search engines, and portals. Summarizing the search for vocabularies that work more intuitively, we see that there are trends working in opposite directions. In the hugely popular taxonomies an the one hand, relationships between terms are more loosely defined than in thesauri. In the ontologies that will support computer-to-computer communications in AI applications such as the Semantic Web, we see the need for much more precisely defined term relationships."

    Rez. in: KO 32(2005) no.2, S.95-97 (A. Gilchrist):"It might be thought unfortunate that the word thesaurus is assonant with prehistoric beasts but as this book clearly demonstrates, the thesaurus is undergoing a notable revival, and we can remind ourselves that the word comes from the Greek thesaurus, meaning a treasury. This is a useful and timely source book, bringing together ten chapters, following an Editorial introduction and culminating in an interview with a member of the team responsible for revising the NISO Standard Guidelines for the construction, format and management of monolingual thesauri; formal proof of the thesaural renaissance. Though predominantly an American publication, it is good to see four English authors as well as one from Canada and one from Denmark; and with a good balance of academics and practitioners. This has helped to widen the net in the citing of useful references. While the techniques of thesaurus construction are still basically sound, the Editors, in their introduction, point out that the thesaurus, in its sense of an information retrieval tool is almost exactly 50 years old, and that the information environment of today is radically different. They claim three purposes for the compilation: "to acquaint or remind the Library and Information Science community of the history of the development of the thesaurus and standards for thesaurus construction. to provide bibliographies and tutorials from which any reader can become more grounded in her or his understanding of thesaurus construction, use and evaluation. to address topics related to thesauri but that are unique to the current digital environment, or network of networks." This last purpose, understandably, tends to be the slightly more tentative part of the book, but as Rosenfeld and Morville said in their book Information architecture for the World Wide Web "thesauri [will] become a key tool for dealing with the growing size and importance of web sites and intranets". The evidence supporting their belief has been growing steadily in the seven years since the first edition was published.

    Rez. in: Online-Mitteilungen 2007, Nr.90, S.18-21 (M. Katzmayr): "Suzanne S. Bell, Bibliothekarin und einschlägig Lehrende, hat ein bemerkenswertes und thematisch sehr breit angelegtes Lehrbuch zur Datenbankrecherche vorgelegt. Die 12 Kapitel lassen sich in drei thematisch zusammengehörende Teile gruppieren: Der erste Teil (Kap. 1-3) vermittelt Grundkenntnisse über Datenbanken. Nach einem kurzen Abriss zur historischen Entwicklung von gedruckten Referats- und Indexierungsdiensten zu kommerziellen Online-Recherchedatenbanken wird die Struktur von Datenbanken anhand des Zusammenhangs von Feldern, Datensätzen und Registerdateien erläutert. Anschließend werden Boolesche Operatoren und Klammersetzung, Verwendung kontrollierten Vokabulars, feldspezifische Suche, Nähesuche, Trunkierung etc. erklärt. Zusätzlich wird auch eine (leider etwas gespreizte) Einführung in die Berechnung von Relevanz- und Trefferquote gegeben. Im zweiten Teil (Kap. 4-8) werden prominente Datenbanken zu den Sozial-, Geistes- und Naturwissenschaften/Medizin vorgestellt, weiters werden Recherchen in Online-Bibliothekskatalogen bzw. Verbundkatalogen und statistischen Datensammlungen erklärt. Neben einigen eingestreuten wissenswerten Hintergrundinformationen (etwa zu Zitationsindizes oder eine kurze Einführung in die Statistikrecherche) werden die Funktionalitäten. ausgewählter Suchoberflächen mittels Beispielrecherchen und Abbildungen ziemlich detailliert veranschaulicht. Thesauri, Indexlisten und der feldspezifischen Suche wird-dabei viel Raum gewidmet. Hinsichtlich der Recherche in Bibliothekskatalogen bzw. Buchverzeichnissen ist auffallend, dass die Autorin ausschließlich für diese den Begriff bibliographische Datenbanken ("bibliographic databases") verwendet und sie dadurch von Referats- und Indexierungsdiensten abzugrenzen versucht, obwohl letztere in der gängigen Fachsprache (1) ebenfalls als bibliographische Datenbanken gehandelt werden. Unklar ist auch, warum dieses Kapitel ausgerechnet zwischen den Ausführungen zu den naturwissenschaftlich/medizinischen und geisteswissenschaftlichen Indexierungsdiensten platziert wurde.
