  • Correlating categories using taxonomy distance and term space distance
    Patent number: 7546278
    Abstract: A method and system for determining similarity or correlation between categories of a hierarchical taxonomy for documents by combining heterogeneous similarity metrics is provided. A correlation system uses both a taxonomy distance metric and a term space distance metric to represent the similarity between categories. The correlation system finds a new distance metric for categories that factors in both the taxonomy distance metric and the term space distance metric. The new distance metric can then be used by classifiers to more accurately represent the correlation between categories.
