Claim One:
1. A computerized method comprising: generating, with a cluster content computer, a hierarchy of clusters of category data, the hierarchy comprises a plurality of levels of different sets of clusters, wherein at least one higher set of clusters is derived from a lower set of clusters and the generating the hierarchy includes, calculating similarity values between clusters in the lower set of clusters, the similarity values are based on a probability distribution for each cluster and an entropic distance metric, the probability distribution for each cluster is a probability of an occurrence of an attribute in the category data occurring in that cluster, and the entropic distance metric is a instance metric of cluster pairs in the lower set of clusters, and identifying a cluster pair in the lower set of clusters that minimizes the loss of information; and representing records of multimedia content as the hierarchy of clusters of category data, wherein the category data is defined in a vector space comprising multiple attributes, and wherein the records comprise category data.
