    Abstract
    Google ist die erste Suchmaschine, die ihre Wurzeln an einer Uni hat. Sie wurde ursprünglich von S. Brin und L. Page aus Stanford lediglich als Proof of Concept implementiert [BP98]. Den gesuchten Beweis für die implementierten Konzepte erbrachte sie aber so überzeugend, dass sie innerhalb weniger Monate zu einer der populärsten universellen Suchmaschinen wurde. Unter den von der Suchmaschine Google zu Testzwecken implementierten Konzepten sind insbesondere zwei Verfahren zum Ranking von Suchergebnissen, auf die in diesem Papier näher eingegangen wird: PageRank (Abschnitt 6) und Anchor Text (Abschnitt 7).

    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
