Abstract

User interfaces of Web search engines reflect attributes of the underlying tools used to create them, rather than what we know about how people look for information. In this article, the author examines several characteristics of user search behavior: the variety of information-seeking goals, the cultural and situational context of search, and the iterative nature of the search task. An analysis of these characteristics suggests ways that interfaces can be redesigned to make searching more effective for users.

Abstract

Web Usability konnte sich als Forschungsbereich zunächst nur in größeren Firmen der Internet-Branche wie z. B. Icon Medialab etablieren. Mit zunehmender Konkurrenz und ersten Pleiten im E-Commerce entsteht die Einsicht oder bittere Erfahrung, dass bunte, multimediale Internetpräsenz nicht alles ist: Die Nutzungsqualität von Websites tritt in den Vordergrund und damit ein neuer Arbeitsmarkt für Informationsarchitekten und HCI- bzw. Usability-Spezialisten. Suchmaschinen sind eine besondere Kategorie von Website. Sie entstehen in einem Spannungsfeld zweier unterschiedlicher Interessen: Mit kommerziellen Websites teilen sie den Wettbewerb um Kunden und die Art der Kunden: den ungeduldigen gelegentlichen Anwender. Mit der akademischen Welt teilen sie das forschende Bemühen um die Optimierung von Features und Funktionen und die déformation professionelle der Eingeweihten. Am Beispiel zweier Untersuchungen wird deutlich, wie es der richtige 'Methodenmix' ermöglicht, bei der Evaluation der Nutzungsqualität von Suchmaschinen ganz unterschiedlicher Art (a) diesen Interessenkonflikt bewusst zu machen, (b) Empathie für die Nöte der Kunden zu entwickeln und c) allgemeingültige Kriterien zur Entwicklung gebrauchstauglicher Suchmaschinen aufzustellen. Beide Untersuchungen fanden im Rahmen des Projekts Jorschung und Forschungsumgebung für Web Usability« unter Mitwirkung von Studierenden am Fachbereich Bibliothek und Information der FH Hamburg statt

Abstract

Those seeking information from the Internet often start from a search engine, using either its organised directory structure or its text query facility. In response to the difficulty in identifying the most relevant pages for some information needs, many search engines offer Boolean text matching and some, including Google, AltaVista and HotBot, offer the facility to integrate additional information into a more advanced request. Amongst web users, however, it is known that the employment of complex enquiries is far from universal, with very short queries being the norm. It is demonstrated that the gap between the provision of advanced search facilities and their use can be bridged, for specific information needs, by the construction of a simple interface in the form of a website that automatically formulates the necessary requests. It is argued that this kind of resource, perhaps employing additional knowledge domain specific information, is one that could be useful for websites or portals of common interest groups. The approach is illustrated by a website that enables a user to search the individual websites of university level institutions in European Union associated countries.
