Abstract

Suchmaschinen bilden den bedeutendsten Zugang zu den im World Wide Web verfügbaren Informationen und haben andere Zugänge zu diesem Informationsbestand (wie etwa Internetverzeichnisse) weitgehend verdrängt. Der Suchmaschinenmarkt ist stark konzentriert; nur wenige Anbieter mit eigener Technologie bieten selbst Endnutzerlösungen an und lizenzieren ihre Technologie an die bekannten Web-Portale wie AOL oder T-Online. Die im vorliegenden Kapitel dargestellten Kennzahlen zur Messung der Qualität von Suchmaschinen basieren einerseits auf Erkenntnissen über den State of the Art der Suchmaschinentechnologie, andererseits stehen sie im Kontext eines umfassenderen Modells der Qualitätsmessung für Web-Suchmaschinen. Die besondere Bedeutung von Erkenntnissen über die Qualität der bestehenden Suchmaschinen ergibt sich einerseits aus ihrer Bedeutung für die Weiterentwicklung der Suchmaschinentechnologie. Qualitätsuntersuchungen geben Hinweise auf die Schwachstellen der Suchmaschinen im Allgemeinen und die ihrer Ranking-Algorithmen im Besonderen. Letztere sind als zentral für die Ergebnisqualität anzusehen und bilden den >Kern< der technologischen Leistungsfähigkeit einer jeden Suchmaschine.
