    Abstract
    In diesem Beitrag werden beispielhaft Probleme der Validität bei Retrievaltests behandelt. Die externe Validität wird im Zusammenhang von Ähnlichkeitsmaßen und Bewertungsmaßen diskutiert. Die interne Validität wird am Beispiel der Mittelwertbildung diskutiert. Es zeigt sich, daß die Forderung nach Validität die zur Auswahl stehenden Methoden einschränkt

    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
