Abstract

We present results of a preliminary study of a pile-based information retrieval interface that supports contextual relevance feedback. We designed two interfaces based on the pile metaphor, one which supported contextual relevance feedback and the other which did not, and conducted a within-subjects laboratory evaluation with 24 subjects. Results demonstrate support for the pile-based approach generally, with users indicating that it assisted them in structuring and managing their search results. There were significant differences between usability assessments of each interface and in the interactions in which subjects engaged while they were seeking information. Although we found no significant differences in performance between interfaces, subjects showed a strong preference for the contextual relevance feedback interface over the other, and believed that they did better with that interface.
