Software repositories such as source code repositories and bug repositories record information about the software development process. By analyzing the rich data available in software repositories, we can uncover interesting information. This information can be leveraged to guide software developers, or to automate software development activities. In this thesis we investigate two activities of the development process: selective code integration and grouping of field crash-reports, and use the information available in software repositories to improve each of the two activities. / Thesis (Master, Electrical & Computer Engineering) -- Queen's University, 2012-09-04 12:26:59.388
