Describes studies conducted at the University of Sheffield that explored the variables during mediated online search interaction. Discuses aspects of the mediated search process, including user satisfaction; relevant information sources; and interaction measures derived from search logs and tape transcripts, and related interaction measures.…

Investigates the regions across a distribution of users' relevance judgments. A multidimensional instrument was designed using four scales for collecting, measuring, and describing end-user relevance judgments, and was administered to 21 end-users who conducted searches on their own information problems and made relevance judgments on a total of…

Reports results from a study exploring the information retrieval (IR) and types of interactive feedback during mediated IR. Five types of interactive feedback were identified, extending the interactive IR model to include relevance, magnitude, and strategy interactive feedback. Implications for further research investigating the nature and models…

Proposes a useful concept of relevance as a relationship and an effect on the movement of a user through the iterative stages of their information seeking process, and that users' relevance judgments can be plotted on a Three-Dimensional Spatial Model of Relevance Level, Degree and Time. Discusses implications for the development of information…
