Tool for visualizing data patterns of a hierarchical classification structure

摘要

A visualization method and tool for gaining insight into the structure of a hierarchy. A derived intuitive display of the relation and effect on classification of features in nodes in a classification hierarchy provides a snapshot of a metric, such as coherence of the hierarchy. The visualization tool displays, in a single view, all or part of the following information: which features are the most powerful in identifying a particular topic; how these features are distributed over items in its sub-classes; which of these features do strongly distinguish among, and help classify items into, subclasses, and which do not (the ones that are shared evenly among the sub-classes justify the grouping as being coherent); and topic relationships among subclasses.
