Abstract
A data set is clustered into one or more initial clusters using a first term space. Initial themes for the initial clusters are determined. The first term space is reduced to create a reduced term space. At least a portion of the data set is reclustered into one or more baby clusters using the reduced term space. One or more singletons are reassigned to form one or more renovated clusters from the baby clusters. A renovated theme is determined for at least some of the renovated clusters. One or more of the renovated clusters and their respective themes are provided as output.
