    Abstract
    Das wachsende Informationsvolumen im WWW führt paradoxerweise zu einer immer schwierigeren Nutzung, das Finden und Verknüpfen von Informationen in einem unstrukturierten Umfeld wird zur Sisyphosarbeit. Hier versprechen Semantic-Web-Ansätze Abhilfe. Die Autoren beschreiben Technologien, wie eine semantische Integration verteilter Daten durch verteilte Ontologien erreicht werden kann. Diese Techniken sind sowohl für Forscher als auch für Professionals interessant, die z.B. die Integration von Produktdaten aus verteilten Datenbanken im WWW oder von lose miteinander verbunden Anwendungen in verteilten Organisationen implementieren sollen.

    Abstract
    Practical Ontologies for Information Professionals provides an accessible introduction and exploration of ontologies and demonstrates their value to information professionals. More data and information is being created than ever before. Ontologies, formal representations of knowledge with rich semantic relationships, have become increasingly important in the context of today's information overload and data deluge. The publishing and sharing of explicit explanations for a wide variety of conceptualizations, in a machine readable format, has the power to both improve information retrieval and discover new knowledge. Information professionals are key contributors to the development of new, and increasingly useful, ontologies. Practical Ontologies for Information Professionals provides an accessible introduction to the following: defining the concept of ontologies and why they are increasingly important to information professionals ontologies and the semantic web existing ontologies, such as RDF, RDFS, SKOS, and OWL2 adopting and building ontologies, showing how to avoid repetition of work and how to build a simple ontology interrogating ontologies for reuse the future of ontologies and the role of the information professional in their development and use. This book will be useful reading for information professionals in libraries and other cultural heritage institutions who work with digitalization projects, cataloguing and classification and information retrieval. It will also be useful to LIS students who are new to the field.

    Footnote
    Rez. in: Mitt. VÖB 62(2009) H.2, S.92-96 (O. Oberhauser): "... Ein kurzes Fazit: Ein lesenswertes Buch, das insbesondere jenen, die sich bislang noch nicht mit Ontologien und semantischen Techniken befasst haben, einen nützlichen ersten Einblick zu geben vermag. Nichts hingegen für Spezialisten, denn der Text kann auf den verfügbaren Seiten an keiner Stelle wirklich in die Tiefe gehen. Insbesondere die beiden ersten Hauptabschnitte sind auch als Lehrtext gut geeignet, selbst wenn an verschiedenen Stellen die Präzision zu wünschen übrig lässt. Gar zu nonchalant wird hier nämlich mit Grundbegriffen der Wissensorganisation umgegangen - z.B. wird der Informationsthesaurus nicht ausreichend vom Synonymenwörterbuch (Roget's) abgegrenzt, Klassifikationssysteme werden durchweg als Taxonomien (mit reduziertem Anspruchsniveau) verkauft. Und: zum Themenbereich "automatisches Klassifizieren" fällt den Autorinnen lediglich das reichlich angestaubte System Scorpion von OCLC ein. Mit diesen kleinen Einschränkungen kann das Werk aber durchaus empfohlen werden. Der Ladenpreis ist natürlich für Studierende bzw. persönliche Käufer zu hoch, doch das Buch wird wohl ohnedies vornehmlich institutionelle Abnehmer finden."
