Abstract

An approach for visualizing versions of a hierarchically organized object is presented. A measure of similarity is computed between each version and a standard version. Versions having identical hierarchies are clustered into sets of versions. Versions within each of the sets of versions are organized according to the computed similarity measures. A visualization is generated as a plot having first and second dimensions. The first dimension represents similarity between a set of versions and the standard version. The second dimension represents similarity between a version and the standard version. In one embodiment, the visualization includes, in a first area, information from multiple hierarchical levels of the standard version and includes, in a second area, information from only the root node level of the other versions. After receiving an approval of a version in the second area, the approved version may replace the standard version in the first area.
