Improving modular structure of software system using structural and lexical dependency

Our combined lexical-structural approach (SLTFIDFW) considering various types of dependencies along with their relative weights performs well and results into better remodularization compared to rest of considered alternates. It also shows significant improvement over techniques based on only lexical or structural information. Thus this approach can be very useful to improve the quality of the software whose remodularization quality deteriorates beyond accepted level.
