    Abstract
    Der Zusammenhang zwischen Topic-Entwicklung und Relevanzbewertung wird anhand einiger Fallbeispiele aus der CLEF-Evaluierungskampagne 2005 diskutiert. Im fachspezifischen Retrievaltest für multilinguale Systeme wurden die Topics am Dokumentenbestand von GIRT entwickelt. Die Zusammenhänge von Topic-Formulierung und Interpretationsspielräumen bei der Relevanzbewertung werden untersucht.

    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
