Abstract: | The quality of a software system is largely determined by its internal structures which always degrade over the software evolution.
Therefore, the structures have to be reconditioned from time to time. However, the existing methods are very complex and resource-consuming
when doing this task. In this paper, we present an approach to recondition the class structures of object-oriented (OO) software
systems. It uses attribute-method networks and method-method networks to represent attributes, methods and dependencies between
them; It proposes a guided community detection algorithm to obtain the optimized community structures in the method-method
networks, which also correspond to the optimized class structures; It also provides a list of refactorings by comparing the
optimized class structures with the real class structure in software systems and inspecting the attribute-method networks.
The approach is evaluated using the open-source case study, JHotDraw 5.1, and the advantages of our approach are illustrated
in comparison with existing methods. |
