In this paper, we present case studies of recovering structural design patterns from object-oriented source code. The proposed recovery technique is based on the use of visual language parsing techniques, and is supported by a visual environment automatically produced by a grammar based visual environment generator. We have applied the recovery technique to public-domain programs and libraries obtaining...
Versioning systems such as CVS exhibit a large potential to investigate and understand the evolution of large software systems. Bug reporting systems such as Bugzilla help to understand which parts of the system are affected by problems. In this article, we present a novel visual approach to uncover the relationship between evolving software and the way it is affected by software bugs. By visually...
There are some concerns in the research community about the convenience of using low-level metrics (such as SLOC, source lines of code) for characterizing the evolution of software, instead of the more traditional higher lever metrics (such as the number of modules or files). This issue has been raised in particular after some studies that suggest that libre (free, open source) software evolves differently...
Software maintenance and reuse require identification of the applied software licenses. The information needs of maintainers and reusers can be supported by reverse engineering tools at different information retrieval levels. The paper presents a reverse engineering approach called ASLA for retrieving license information typically used in OSS. User needs, system architecture, tool features, and tool...
