I have started my summer intern at Samsung Research America/Advanced Printing Software Lab since June 2015.
Our paper named “An Empirical Study of Architectural Change in Open-Source Software Systems” will be appeared in the Proceeding of the 12th Working Conference on Mining Software Repositories (MSR 2015)
Abstract-From its very inception, the study of software architecture has recognized architectural decay as a regularly occurring phenomenon in long-lived systems. Architectural decay
is caused by repeated changes to a system during its lifespan. Despite decay’s prevalence, there is a relative dearth of empirical data regarding the nature of architectural changes that may lead
to decay, and of developers’ understanding of those changes. In this paper, we take a step toward addressing that scarcity by conducting an empirical study of changes found in software
architectures spanning several hundred versions of 14 opensource systems. Our study reveals several new findings regarding the frequency of architectural changes in software systems, the
common points of departure in a system’s architecture during maintenance and evolution, the difference between system-level and component-level architectural change, and the suitability
of a system’s implementation-level structure as a proxy for its architecture.
