Adjusting dependency-based software clusters using semantic cohesion

Abstract (in Japanese) (See Japanese page) 
(in English) Software clustering techniques have been used to divide a software system into smaller parts. Especially, dependency-based clustering is able to extract software clusters that implement features of the system. However, using only dependencies sometimes leads to inappropriate results, for example, a cluster that contains two or more distinct features. To solve this problem, combining dependency- and semantic-based approaches will hopefully prove successful. In this paper, we used a topic modeling technique to evaluate the semantic cohesion of a cluster that is extracted with dependency-based clustering and then low-cohesive clusters are divided in accordance with the cluster hierarchy. This method ensures that the obtained clusters are actually used together and also semantically cohesive, which is suitable with respect to the demand for extracting service candidates to restructure legacy applications. We evaluated the method using a real business application developed and used in a company that is under consideration for migration into microservice architecture.
