In recent years, an increasingly large number of software systems have been developed at different geographical regions. As a result, the maintenance and evolution of those systems have shifted from being conducted at a single site to being ...

Software architectures play a key role for the development and evolution of software systems because they have to enable their quality properties such as scalability, flexibility, and security. Software architectural decisions represent a transition ...

Characterising and measuring software developed in multiple languages is a problem for practitioners. Rather than a language-based approach, we avoid difficulties related to syntax, semantics and language paradigms by looking directly at relative shared ...

The Gini coefficient is a prominent measure to quantify the inequality of a distribution. It is often used in the field of economy to describe how goods, e.g., wealth or farmland, are distributed among people. We use the Gini coefficient to measure code ...

Logical dependencies are implicit relationships established between software artifacts that have evolved together. Software engineering researchers have investigated this kind of dependency to assess fault-proneness, detect design issues, infer code ...

Rigorously evaluating and comparing traceability link generation techniques is a challenging task. In fact, traceability is still expensive to implement and it is therefore difficult to find a complete case study that includes both a rich set of ...

It is our great pleasure to welcome you to the 2011 12th International Workshop on Principles on Software Evolution and 7th ERCIM Workshop on Software Evolution -- IWPSE-EVOL 2011. Research in software evolution and evolvability has been thriving in the ...
