- "Wer Google googelt, sieht zuallererst Google. Das klingt wie ein plattes Witzchen - ist aber schon das wesentliche Geheimnis des unheimlichen Erfolgs einer Suchmaschine, der es gelungen ist, binnen weniger Jahre das Internet, die Suche nach Informationen und die Werbewelt zu verändern und sich unentbehrlich zu machen. Googeln wurde buchstäblich zum Begriff. "Keine andere Marke hat je so schnell globale Anerkennung gefunden wie Google", schreiben David A. Vise, ein Reporter der "Washington Post", und sein Kollege Mark Malseed in ihrem Buch über den sagenhaften Aufstieg des Unternehmens, das Suchergebnisse in 35 Sprachen liefert. Allein in Deutschland nutzen heute über 22 Millionen Menschen die Suchmaschine mit den bunten Buchstaben regelmäßig - unter den Internet-Surfern hierzulande ein Marktanteil von 65 Prozent. Sie suchen nach Neuigkeiten über ihre Filmhelden, prüfen die Schreibweise von Fremdwörtern oder forschen wie Detektive nach Wissenswertem über die Frau oder den Mann, mit dem sie sich abends treffen werden - zum Rendezvous oder Geschäftsessen. Längst gelten in manchen Kreisen Menschen als Langweiler, über die selbst Google nichts weiß. Wie dieser Erfolg möglich war, beschreiben Vise und Malseed auf rund 300 Seiten. Man kann es mit dem Dichter Victor Hugo (1802-1885) aber auch kürzer sagen: "Nichts ist so mächtig wie eine Idee, deren Zeit gekommen ist." Noch mächtiger freilich ist eine Idee, die von der Konkurrenz übernommen wird - in totaler Verkennung der Bedürfnisse von Internet-Nutzern. Eine solche Idee brachte 1997 Google hervor - und hat längst Wirtschafts- und Kulturgeschichte geschrieben. Der zentrale Gedanke der beiden damals 22-jährigen Google-Gründer Larry Page und Sergey Brin ist simpel: Wenn die Lawine der im Internet abrufbaren Informationen weiter derart anschwillt, dann brauchen die Nutzer des weltweiten Netzes einen exzellenten Suchhund. Nicht umsonst ist der Name der Suchmaschine abgeleitet von dem Wort Googol, womit in der Mathematik eine absurd große Zahl mit hundert Nullen bezeichnet wird - eine Anspielung auf die unermessliche und längst unüberschaubare Weite des Internets.

- 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
