- Abstract
- Die Arbeit untersucht die Usability von Online-Wörterbüchern und elektronischen Sprachportalen und soll eine Brücke zwischen der Usability von Websites hinsichtlich softwareergonomischer Normen und Konventionen und Wörterbüchern in elektronischer Form schlagen. Die einzige Usability-Methode, mit der es möglich ist, konkrete und empirisch belegte Aussagen darüber zu treffen, wie potentielle Nutzer ein Online-Wörterbuch verwenden und welche Probleme dabei festgestellt werden, ist ein Usability- Test mit realen Benutzern. Als Untersuchungsgegenstand dient das Online-Wortschatz-Informationssystem Deutsch (Owid), die Base lexicale du français (BLF) und das elektronische Lernerwörterbuch Deutsch-Italienisch (Eldit). Die Arbeit setzt sich aus vier verschiedenen empirischen Studien zusammen. Da ein Usability-Test immer nur einen Ausschnitt an Funktionalitäten aus einem gesamten System widerspiegeln kann, wurden mithilfe einer empirischen Fragebogen-Studie zunächst die für den Benutzer wichtigsten und am meisten verwendeten Funktionen eines Online-Wörterbuchs identifiziert und als Grundlage für den Test gewählt. Eine anschließende heuristische Evaluation trug potentielle Usability-Probleme der drei Online- Wörterbücher zusammen und stellte die Grundlage für die Thesenstellung des Usability-Tests dar. Der Test setzte sich aus zwei empirischen Teilen zusammen: Einem Aufgabenteil, den die Testperson für jedes der drei Online-Wörterbüchern einzeln bearbeiten und dabei die Testmethode des lauten Denkens anwenden musste und einem Post-Test- Fragebogen, der direkt nach dem Bearbeiten des jeweiligen Aufgabenkatalogs ausgefüllt wurde. Der gesamte Test wurde mit Morae, einer Software u. a. für Software- und Website- Usability-Tests, durchgeführt und ausgewertet.
