Title
Wissenschaftliche Suchmaschinen : Usability Evaluation und Betrachtung des Suchverhaltens potentieller Nutzer

Abstract
Wissenschaftliche Suchmaschinen haben es nicht leicht in einer "Amazoogle" gestalteten Welt. Dabei ist nicht nur die Einfachheit der Benutzerschnittstelle d.h. die Umsetzung von Usability-Anforderungen entscheidend für den Erfolg, sondern ebenso die Qualität der Suchergebnisse. Im Rahmen des Masterprojektes "Wissenschaftliche Suchmaschinen" an der Hochschule Darmstadt werden benutzerspezifische Bedürfnisse, Anforderungen und Aspekte der Wahrnehmung in Relation zum individuellen Informationssuchverhalten aufgerollt und methodisch evaluiert. Es wird der Fragestellung nachgegangen, was die Informationssuche auszeichnet und welche Rolle die Informationskompetenz der Nutzer in diesem Rahmen spielt. Anschließend werden die Ergebnisse detailliert skizziert, analysiert und daraus Rückschlüsse auf die zielgruppenspezifischen Anforderungen und Bedürfnisse hinsichtlich der Gestaltung von wissenschaftlichen Suchmaschinen gezogen.
