With the rise of interactive search engines, direct access to information is available to the end user. Evaluation of these systems is clearly important for their comparison and development. From the perspective of the user engaged with the system in some information-seeking task, the range of relevant evaluation factors could be considerable. This article presents an investigation into the suitability of repertory grid technique eliciting a mental model of search engines in the user. Such a model comprises constructs held important to the user, which can be used to evaluate the system. The design of the repertory grid application is described and the data analyzed in two stages. The important issues in determining the suitability of the method are identified and the constructs are analyzed to determine their association, discriminatory ability, and clustering around a central overall rating. From this, it is concluded that repertory grid technique is appropriate for user-centered determination of evaluative constructs. Further analysis of the characteristics of the resulting construct set is undertaken towards establishing an underlying user model of the search engines, and further research is identified for its use in system evaluation.

A flexible interface design for Web directories to accommodate different cognitive styles

Search engines are very popular tools for collecting information from distributed resources. They provide not only search facilities, but they also offer directories for users to browse content divided into groups. In this paper, we've adopted an individual differences approach to explore user's attitudes towards various interface features provided by existing Web directories. Among a variety of individual differences, cognitive style is a particularly important characteristic that influences the effectiveness of information seeking. Empirical results indicate that users' cognitive styles influence their reactions to the organization of subject categories, presentation of the results, and screen layout. We developed a set of design guidelines on the basis of these results, and propose a flexible interface that adopts these guidelines to accommodate the preferences of different cognitive style groups.
