In this paper, we present an approach to clustering in text-based information retrieval systems. The proposed method generates overlapping clusters, each of which is composed of subsets of associated terms and documents with normalized significance weights. In the paper, we first briefly introduce the probabilistic formulation of our clustering scheme and then show the procedure for cluster generation. We also report some experimental results, where the generated clusters are investigated in the framework of automatic text categorization.
