Describes the development of a method for the evaluation and comparison of interactive information retrieval systems, which are based on the concept of a simulated work-task situation and the involvement of real end users. Highlights include real and simulated information needs; relevance assessments; and the dynamic nature of information needs.…

This paper discusses the research into information seeking and its directions at a general level. We approach this topic by analysis and argumentation based on past research in the domain. We begin by presenting a general model of information seeking and retrieval which is used to derive nine broad dimensions that are needed to analyze information…

Outlines principles underlying the theory of polyrepresentation as it applies to user cognitive space and information space of information retrieval (IR) systems. A discussion and diagram illustrate the interactive communication that takes place between users and IR systems in order to complete work tasks such as retrieving full text information.…
