    Abstract
    Section 11: To argue that fighting large search engines and plagiarism slice-by-slice by using dedicated servers combined by one hub could eventually decrease the importance of other global search engines. Section 12: To argue that global search engines are an area that cannot be left to the free market, but require some government control or at least non-profit institutions. We will mention other areas where similar if not as glaring phenomena are visible. Section 13: We will mention in passing the potential role of virtual worlds, such as the currently overhyped system "second life". Section 14: To elaborate and try out a model for knowledge workers that does not require special search engines, with a description of a simple demonstrator. Section 15 (Not originally part of the proposal): To propose concrete actions and to describe an Austrian effort that could, with moderate support, minimize the role of Google for Austria. Section 16: References (Not originally part of the proposal) In what follows, we will stick to Sections 1 -14 plus the new Sections 15 and 16 as listed, plus a few Appendices.

    "Am 7. September feiert die Google-Seite ihren zehnten Geburtstag. Die Bilanz dieser Dekade ist durchaus überwältigend. Gerade bescheinigte das Marktforschungs-Unternehmen comScore Google einen Anteil von 61,6 Prozent am weltweiten Suchmaschinen-Markt. Der Gigant aus Mountain View machte letztes Jahr 16,5 Milliarden US-Dollar Umsatz und erwirtschaftete 4,2 Milliarden US-Dollar Gewinn - gegenüber 2006 ein Plus von bemerkenswerten 30 Prozent. Viele Gründe zum Feiern. Eigentlich. Doch die Stimmung beim weltgrößten Suchmaschinen-Betreiber ist getrübt. Die gleichen Marktforscher sagen Google nämlich ein Ende der glorreichen Zeiten voraus. Die Gründe: Die User verstecken sich vor Google, klicken seltener auf Werbebanner und achten stärker denn je auf ihre Privatsphäre im Internet. In den USA schrumpfte das Anzeigengeschäft allein von Dezember 2007 bis Januar 2008 um sieben Prozent. Der Aktienkurs der Suchmaschine brach ob dieser Zurückhaltung ein, seit letztem November verlor Google 40 Prozent seines Börsenwertes - immerhin 80 Milliarden US-Dollar. Das rückläufige Geschäft verdeutlicht ein gravierendes Problem. Es wird für Google immer schwerer, Werbung dort einzublenden, wo die Webnutzer sind. Die Platzierung funktioniert vereinfacht so: Um seinen Webseitenindex aktuell zu halten, schickt Google Crawler durch das Web. Sie erfassen für das Indizierungs-Programm Google-bot die Inhalte der Webseiten - anhand häufig auftauchender Begriffe sowie von Content- und Title-Tags. So weiß Google, auf welchen Seiten welche Inhalte stehen und kann passende Werbung schalten. In Zeiten dröger HTML-Seiten war das mehr als ausreichend. Doch das Web hat sich schneller geändert als Google seinen Googlebot. Der nämlich kann nicht alle Seitenformate erfassen. Die Inhalte von Flash-Dateien und dynamischen Webseiten etwa bleiben außen vor, zielgenaue Werbung lässt sich hier nicht schalten. Dummerweise boomen ausgerechnet diese Formate im populären "Web 2.0". Eigentlich ein rein technisches Problem, für das die Suchmaschine noch keine Lösung hat.

    Abstract
    Die deutschen Suchmaschinen, Abacho, Acoon, Fireball und Lycos sowie die Web-Kataloge Web.de und Yahoo! werden einem Qualitätstest nach relativem Recall, Precision und Availability unterzogen. Die Methoden der Retrievaltests werden vorgestellt. Im Durchschnitt werden bei einem Cut-Off-Wert von 25 ein Recall von rund 22%, eine Precision von knapp 19% und eine Verfügbarkeit von 24% erreicht
