Background: Code smells indicate suboptimal design or implementation choices in the
source code that often lead it to be more change-and fault-prone. Researchers defined …

Predictive models are one of the most important techniques that are widely applied in many
areas of software engineering. There have been a large number of primary studies that …

Defect prediction models-classifiers that identify defect-prone software modules-have
configurable parameters that control their characteristics (eg, the number of trees in a …

Patching is a common activity in software development. It is generally performed on a source
code base to address bugs or add new functionalities. In this context, given the recurrence of …

Unlike traditional defect prediction models that identify defect-prone modules, Just-In-Time
(JIT) defect prediction models identify defect-inducing changes. As such, JIT defect models …

Researchers in software engineering have attempted to improve software development by
mining and analyzing software repositories. Since the majority of the software engineering …

Topic modeling using models such as Latent Dirichlet Allocation (LDA) is a text mining
technique to extract human-readable semantic “topics”(ie, word clusters) from a corpus of …

Prior research suggests that predicting defect-inducing changes, ie, Just-In-Time (JIT) defect
prediction is a more practical alternative to traditional defect prediction techniques, providing …

Issue tracking systems are commonly used in modern software development for collecting
feedback from users and developers. An ultimate automation target of software maintenance …

Bug report assignment is an important part of software maintenance. In particular, incorrect
assignments of bug reports to development teams can be very expensive in large software …
