Patent ID: 8005862

Claim:
A computer-implemented method for classifying a set of content resources, the set of content resources being characterized by structured patterns among features associated with the content resources, wherein the features are metadata associated with each content resource, and wherein the structured patterns represent a multidimensional space and each of the content resources corresponds to a vector in the multidimensional space, the vector being populated by the features of the corresponding content resource, the method comprising: enriching the vector of features associated with each of selected ones of the content resources with reference to the structured patterns by traversing a hierarchy of the structured patterns to identify at least one additional feature not originally included in the vector of features for inclusion in the vector of features thereby reducing data sparsity of the multidimensional space; and classifying each of the content resources with reference to the associated vector of features and a predefined classification schema not associated with the set of content resources.
