A computerized method of representing a dataset with a taxonomy includes representing a plurality of records within a dataset as a plurality of clusters in an initial taxonomy layer; generating a hierarchy of cluster sets based on clusters within the initial taxonomy layer, wherein the structure of the hierarchy is independent of the order of the records within the dataset; and labeling clusters within the hierarchy.

Method and system for order invariant clustering of categorical data

Records including category data is clustered by representing the data as a plurality of clusters, and generating a hierarchy of clusters based on the clusters. Records including category data are classified into folders according to a predetermined entropic similarity condition.

Clustering and classification of multimedia data

A computerized method of representing a dataset with a taxonomy includes augmenting a dataset containing a plurality of records with a plurality of predetermined exemplars; representing the plurality of records and predetermined exemplars within the augmented dataset as a plurality of clusters in an initial taxonomy layer; generating a truncated hierarchy of cluster sets based on clusters within the initial taxonomy layer, wherein clusters within the truncated hierarchy contain no more than a predetermined number of exemplars; and labeling clusters within the truncated hierarchy.
