Abstract

In einem Labor-Experiment wurden insgesamt achtzehn Studenten und Studentinnen mit zwei offenen Web-Rechercheaufgaben konfrontiert. Während deren Bewältigung mit einer Suchmaschine wurden sie per Proxy-Logfile-Protokollierung verdeckt beobachtet. Sie machten demographische und ihre Webnutzungs-Gewohnheiten betreffende Angaben, bewerteten Aufgaben-, Performance- und Suchmaschinen-Eigenschaften in Fragebögen und stellten sich einem Multiple-Choice-Test zu ihrem Wissen über Suchmaschinen. Die Versuchspersonen wurden gezielt angeworben und eingeteilt: in eine erfahrene und eine unerfahrene Untergruppe mit je neun Teilnehmern. Die Untersuchung beruht auf dem Vergleich der beiden Gruppen: Im Zentrum stehen dabei die Lesezeichen, die sie als Lösungen ablegten, ihre Einschätzungen aus den Fragebögen, ihre Suchphrasen sowie die Muster ihrer Suchmaschinen-Interaktion und Navigation in Zielseiten. Diese aus den Logfiles gewonnen sequentiellen Aktionsmuster wurden vergleichend visualisiert, ausgezählt und interpretiert. Zunächst wird das World Wide Web als strukturell und inhaltlich komplexer Informationsraum beschrieben. Daraufhin beleuchtet der Autor die allgemeinen Aufgaben und Typen von Meta-Medienanwendungen, sowie die Komponenten Index-basierter Suchmaschinen. Im Anschluß daran wechselt die Perspektive von der strukturell-medialen Seite hin zu Nutzungsaspekten. Der Autor beschreibt Nutzung von Meta-Medienanwendungen als Ko-Selektion zwischen Nutzer und Suchmaschine auf der Basis von Entscheidungen und entwickelt ein einfaches, dynamisches Phasenmodell. Der Einfluß unterschiedlicher Wissensarten auf den Selektionsprozeß findet hier Beachtung.Darauf aufbauend werden im folgenden Schritt allgemeine Forschungsfragen und Hypothesen für das Experiment formuliert. Dessen Eigenschaften sind das anschließende Thema, wobei das Beobachtungsinstrument Logfile-Analyse, die Wahl des Suchdienstes, die Formulierung der Aufgaben, Ausarbeitung der Fragebögen und der Ablauf im Zentrum stehen. Im folgenden präsentiert der Autor die Ergebnisse in drei Schwerpunkten: erstens in bezug auf die Performance - was die Prüfung der Hypothesen erlaubt - zweitens in bezug auf die Bewertungen, Kommentare und Suchphrasen der Versuchspersonen und drittens in bezug auf die visuelle und rechnerische Auswertung der Suchmuster. Letztere erlauben einen Einblick in das Suchverhalten der Versuchspersonen. Zusammenfassende Interpretationen und ein Ausblick schließen die Arbeit ab
