Abstract
A number of levels of a cluster hierarchy may be determined, and a current level of the levels may be obtained by providing a current input to at least one clustering algorithm to thereby obtain a current output of the at least one clustering algorithm, where the current output includes a current plurality of clusters and defines the current level. Content information associated with each cluster of the current output from the at least one clustering algorithm may be aggregated to obtain aggregated content information for each cluster of the current output. The obtaining and the aggregating may be repeated, using the aggregated content information as the new current input, to thereby obtain a new current output defining a new current level during the obtaining, and using the new current output during the aggregating, until the new current level equals the number of levels.
