Claim One:
1. A system, comprising: a processor configured to: cluster a data set into one or more initial clusters using a first term space comprising a plurality of keywords; determine an initial theme for each initial cluster, wherein the initial theme for each initial cluster is determined based on at least one keyword in the first term space; reduce the first term space to create a reduced term space, wherein reducing the first term space includes removing from the first term space a keyword term that is determined to be present in a first document clustered into a first initial cluster and is also determined to be present in a second document clustered into a second initial cluster, and wherein a term frequency for the keyword at least meets a predetermined threshold; recluster at least a portion of the data set into one or more baby clusters using the reduced term space, wherein after reclustering, at least one singleton is present, wherein a singleton is an element from the data set that was not assigned to any baby clusters during the reclustering; assign at least one singleton to a baby cluster to form one or more renovated clusters; determine a renovated theme for at least one of the renovated clusters; and provide as output one or more of the renovated clusters and their respective themes; and a memory coupled to the processor and configured to provide the processor with instructions.
