Abstract

The classic TileBars paradigm has been used to show distribution information of query terms in full-text documents. However, when the number of query terms becomes large, it is not an easy task for users to comprehend their distribution within certain parts of a document. In this paper, we present a novel approach to improve the visual presentation of TileBars, in which barycenter heuristic for bigraph crossing minimization is used to reorder TileBars elements. The reordered TileBars can be demonstrated to provide users with better focus and navigation while exploring text documents.
