    Abstract
    Google ist zum Inbegriff einer Suchmaschine geworden. Doch ist in Fachkreisen klar, dass Volltexsuchtmaschinen wie Google auch deutliche Schwächen aufweisen und deshalb für die effiziente Suche in Fachportalen, Intranets und Enterprise-Content-Management-Systemen oft nicht ausreichen. Weil Volltextsuchmaschinen nur mit dem genauen Wortlaut suchen, finden sie einerseits Informationen nicht, die zwar dem Inhalt, nicht aber den genauen Formulierungen der Suchanfrage entsprechen. Bezeichnungsalternativen, sprachlichen Varianten sowie fremdsprachliche Benennungen werden nicht als bedeutungsgleich erkannt. Andererseits entstehen unpräzise Suchergebnisse, weil gleich lautende Bezeichnungen unterschiedlicher Bedeutung nicht unterschieden werden. Diese Probleme geht die semantische Suchmaschine ConWeaver an, die das Fraunhofer Institut Integrierte Informations- und Publikationssysteme (Fraunhofer IPSI) in Darmstadt entwickelt hat. An Stelle eines Volltextindexes setzt sie ein Wissensnetz als Suchindex ein. Im Unterschied zu den meisten anderen ontologiebasierten Softwareprodukten baut die Software ConWeaver dieses Wissensnetz automatisiert auf.

    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."

    Abstract
    Das Werk behandelt die aktuellen Entwicklungen zur inhaltlichen Erschließung von Informationsquellen im Internet. Topic Maps, semantische Modelle vernetzter Informationsressourcen unter Verwendung von XML bzw. HyTime, bieten alle notwendigen Modellierungskonstrukte, um Dokumente im Internet zu klassifizieren und ein assoziatives, semantisches Netzwerk über diese zu legen. Neben Einführungen in XML, XLink, XPointer sowie HyTime wird anhand von Einsatzszenarien gezeigt, wie diese neuartige Technologie für Content Management und Information Retrieval im Internet funktioniert. Der Entwurf einer Abfragesprache wird ebenso skizziert wie der Prototyp einer intelligenten Suchmaschine. Das Buch zeigt, wie Topic Maps den Weg zu semantisch gesteuerten Suchprozessen im Internet weisen.
