Abstract

Gegenstand dieser Arbeit ist die Entwicklung eines funktionalen Prototyps einer Webanwendung für die Verknüpfung der Evaluierung von explorativen Suchen in Verbindung mit der Durchführung klassisches Retrievaltests. Als Grundlage für die Programmierung des Prototyps werden benutzerorientierte und systemorientierte Evalulierungsmethoden für Suchmaschinen analysiert und in einem theoretischen Modell zur Untersuchung von Informationssysteme und Suchmaschinen kombiniert. Bei der Gestaltung des Modells und des Prototyps wird gezeigt, wie sich aufgezeichnete Aktionsdaten praktisch für die Suchmaschinenevaluierung verwenden lassen, um auf der einen Seite eine Datengrundlage für Retrievaltests zu gewinnen und andererseits, um für die Auswertung von Relevanzbewertungen auch das implizierte Feedback durch Handlungen der Anwender zu berücksichtigen. Retrievaltests sind das gängige und erprobte Mittel zur Messung der Retrievaleffektiviät von Informationssystemen und Suchmaschinen, verzichten aber auf eine Berücksichtigung des tatsächlichen Nutzerverhaltens. Eine Methode für die Erfassung der Interaktionen von Suchmaschinennutzern sind protokollbasierte Tests, mit denen sich Logdateien über Benutzer einer Anwendung generieren lassen. Die im Rahmen der Arbeit umgesetzte Software bietet einen Ansatz, Retrievaltests auf Basis protokollierter Nutzerdaten in Verbindung mit kontrollierten Suchaufgaben, durchzuführen. Das Ergebnis dieser Arbeit ist ein fertiger funktionaler Prototyp, der in seinem Umfang bereits innerhalb von Suchmaschinenstudien nutzbar ist.
