    Abstract
    As the World Wide Web continues to expand, it becomes increasingly difficult for users to obtain information efficiently. Because most search engines read format languages such as HTML or SGML, search results reflect formatting tags more than actual page content, which is expressed in natural language. Spinning the Semantic Web describes an exciting new type of hierarchy and standardization that will replace the current "Web of links" with a "Web of meaning." Using a flexible set of languages and tools, the Semantic Web will make all available information - display elements, metadata, services, images, and especially content - accessible. The result will be an immense repository of information accessible for a wide range of new applications. This first handbook for the Semantic Web covers, among other topics, software agents that can negotiate and collect information, markup languages that can tag many more types of information in a document, and knowledge systems that enable machines to read Web pages and determine their reliability. The truly interdisciplinary Semantic Web combines aspects of artificial intelligence, markup languages, natural language processing, information retrieval, knowledge representation, intelligent agents, and databases.

    Abstract
    Suchmaschinen sind die neuen »Gatekeeper« im Internet. Sie kanalisieren unsere Aufmerksamkeit und haben entscheidenden Einfluss darauf, welche Inhalte wie zugänglich sind. Ohne sie sind Informationen im Netz nur schwer auffindbar. Allerdings: Nur wenige Nutzer wissen, wie man Suchmaschinen optimal bedient und wie sie funktionieren. Sie sind anfällig für Manipulationen (»Spamming«) und verschaffen auch ungewollt Zugang zu illegalen und jugendgefährdenden Inhalten. Wie können Suchmaschinen trotzdem ihrer Verantwortung als zentrale Informationssortierer gerecht werden? Eine groß angelegte Untersuchung der Bertelsmann Stiftung stellt diese Beobachtungen auf eine wissenschaftliche Basis. Eine Nutzerbefragung, ein Laborexperiment und ein Leistungsvergleich geben Aufschluss über Image, Bedienerfreundlichkeit und Qualität von Suchmaschinen. Aus dieser Analyse entwickeln die Autoren einen Code of Conduct für Suchmaschinenbetreiber, der einen möglichst objektiven und transparenten Zugang zu Informationen im Netz garantieren soll. Das Buch ist dreigeteilt: Im ersten umfangreichen Teil (bis Seite 490) werden, nach einer Einführung in die Suchmaschinenproblematik und ihr Umfeld, Qualität und Nutzung erforscht: Nach der Marktanalyse der deutschsprachigen Suchdienste werden ausgewählte einem Leistungsvergleich unterzogen. Der Gefährdung von Kindern und Jugendlichen widmet sich das Kapitel Problemanalyse. Wie erfolgreich Spamversuche die Suchergebnisse beeinflussen können, wird anschließend dargestellt. Den Kenntnissen und Einstellungen von Nutzern von Suchdiensten widmet sich ein ausführliches Kapitel. Nutzungshäufigkeit, Suchprozesse und Vorgehensweisen sind detailliert untersucht worden. Die Ergebnisse der Laborexperimente liefern konkrete Einsichten, auf über 100 Seiten verständlich beschrieben. In Kapitel 6 werden die angewandten Methoden ausführlich erläutert. Das angefügte Glossar könnte ausführlicher sein. Der zweite Teil appelliert an die gesellschaftliche Verantwortung der deutschen Suchdienstbetreiber, indem ein Code of Conduct für Suchmaschinen entworfen wird. Im dritten Teil wird auf die Entwicklungen in der Suchmaschinenlandschaft eingegangen, die sich durch Firmenübernahmen und die Monopolstellung von Google ergeben haben.

    Footnote
    Some of the pieces are more captivating than others and less "how-to" in nature, providing contextual discussions as well as pragmatic advice. For example, Darlene Fichter's "Blogging Your Life Away" is an interesting discussion about creating and maintaining blogs. (For those unfamiliar with the term, blogs are frequently updated Web pages that ]ist thematically tied annotated links or lists, such as a blog of "Great Websites of the Week" or of "Fun Things to Do This Month in Patterson, New Jersey.") Fichter's article includes descriptions of sample blogs and a comparison of commercially available blog creation software. Another article of note is Kelly Broughton's detailed account of her library's experiences in initiating Web-based reference in an academic library. "Our Experiment in Online Real-Time Reference" details the decisions and issues that the Jerome Library staff at Bowling Green State University faced in setting up a chat reference service. It might be useful to those finding themselves in the same situation. This volume is at its best when it eschews pragmatic information and delves into the deeper, less ephemeral libraryrelated issues created by the rise of the Internet and of the Web. One of the most thought-provoking topics covered is the issue of "the serials pricing crisis," or the increase in subscription prices to journals that publish scholarly work. The pros and cons of moving toward a more free-access Web-based system for the dissemination of peer-reviewed material and of using university Web sites to house scholars' other works are discussed. However, deeper discussions such as these are few, leaving the volume subject to rapid aging, and leaving it with an audience limited to librarians looking for fast technological fixes."

    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.
