Changes in software development come in many forms. Some changes are frequent, idiomatic, or repetitive (e.g. Adding checks for nulls or logging important values) while others are unique. We hypothesize that unique changes are different from the more common similar (or non-unique) changes in important ways, they may require more expertise or represent code that is more complex or prone to mistakes...
The paper presents an approach, namely iHDev, to recommend developers who are most likely to implement incoming change requests. The basic premise of iHDev is that the developers who interacted with the source code relevant to a given change request are most likely to best assist with its resolution. A machine-learning technique is first used to locate source code entities relevant to the textual...
Developers frequently employ Copy and Paste. However, little is known about the copy and paste behavior during development. To better understand the copy and paste behavior, automated approaches are proposed to identify cloned code. However, such automated approaches can only identify the location of the code that has been copied and pasted, but little is known about the context of the copy and paste...
Popular open-source software projects receive and review contributions from a diverse array of developers, many of whom have little to no prior involvement with the project. A recent survey reported that reviewers consider conformance to the project's code style to be one of the top priorities when evaluating code contributions on Github. We propose to quantitatively evaluate the existence and effects...
Deep learning subsumes algorithms that automatically learn compositional representations. The ability of these models to generalize well has ushered in tremendous advances in many fields such as natural language processing (NLP). Recent research in the software engineering (SE) community has demonstrated the usefulness of applying NLP techniques to software corpora. Hence, we motivate deep learning...
The quality of software projects is affected by developer turnover. Mockus studied organizational volatility in the context a large switching software project at Avaya. We replicate his model of the impact of organizational volatility on post-release defects. At the time of Mockus's study, Avaya was experimenting with outsourcing and layoffs were prevalent. In contrast, we study volatility on the...
In recent times, gamification has become a popular technique to aid online communities stimulate active member participation. Gamification promotes a reward-driven approach, usually measured by response-time. Possible concerns of gamification could a trade-off between speedy over quality responses. Conversely, bias toward easier question selection for maximum reward may exist. In this study, we analyze...
