Using clustering algorithms in legacy systems remodularization

Incited by the observation that cluster analysis and the remodularization of software systems solve similar problems, we have done research in both these areas in order to provide theoretical background for the application of cluster analysis in systems remodularization. We present an overview of cluster analysis and of systems remodularization. It appears that system remodularization techniques often either reinvent clustering techniques or could be augmented by them. We also give directions for further research
