We are interested in questions of control for best-match text-retrieval systems, specifically questions as to whether simple visualizations that nonetheless go beyond the minimal ones generally available can significantly help users. Recently, we have been investigating ways to help users decidegiven a set of documents retrieved by a querywhich documents and passages are worth closer examination.
We built a document viewer incorporating a visualization centered around a novel content-displaying scrollbar and color term highlighting, and studied whether the visualization is helpful to non-expert searchers. Participants reaction to the visualization was very positive, while the objective results were inconclusive.
