The concept of variability is not new in software engineering, but current research mostly remains vague about the overall variability concept when it comes to giving a clear overview of the dimensions of variability. In this paper we evaluate the core variability concept by proposing an...

Patterns for software development have been a hot topic for some time within the object-oriented community. Patterns are part of a software engineering problem-solving discipline. It all started with Design Patterns [11], but gradually patterns were used in a larger number of areas of system...

In software defect prediction, predictive models are estimated based on various code attributes to assess the likelihood of software modules containing errors. Many classification methods have been suggested to accomplish this task. However, association based classification methods have not been...
