User Review-Based Change File Localization for Mobile Applications
share
In the current mobile app development, novel and emerging DevOps practices (e.g., Continuous Delivery, Integration, and user feedback analysis) and tools are becoming more widespread. For instance, the integration of user feedback (provided in form of user reviews) in the software release cycle represents a valuable asset for the maintenance and evolution of mobile apps. To fully make use of these assets, it is highly desirable for developers to establish semantic links between the user reviews and the software artefacts to be changed (e.g., source code and documentation), and thus to localize the potential files to change for addressing the user feedback. In this paper, we propose EINSTEIN (usEr-revIews iNtegration via claSsification, clusTEring, and linkINg), an automated approach to support the continuous integration of user feedback via classification, clustering, and linking of user reviews. EINSTEIN leverages domain-specific constraint information and semi-supervised learning to group user reviews into multiple fine-grained clusters concerning similar users' requests. Then, by combining the textual information from both commit messages and source code, it automatically localizes potential change files to accommodate the users' requests. Our empirical studies demonstrate that the proposed approach (significantly) outperforms the state-of-the-art baseline work in terms of clustering and localization accuracy, and thus produces more reliable results.
