They propose a novel browser, HishiMochi, for searching and browsing hierarchically clustered documents. HishiMochi visualizes a hierarchy of clusters and documents as nested rectangles with multi-focus distortion views and animation. It provides suitable views for various search phases, by dynamically changing the DOI (Degree of Interest) function. Using HishiMochi, the user can easily search multiple target documents scattered in the hierarchy, and seamlessly browse their contents in a few operations. |
