It is now understood that software metrics alone are not enough to characterize software quality. To cope with this problem, most of advanced and/or industrially validated quality models aggregate software metrics: for example, cyclomatic complexity is combined with test coverage to stress the fact that it is more important to cover complex methods than accessors. Yet, aggregating and weighting metrics...
Software re-modularization is an old preoccupation of reverse engineering research. The advantages of a well structured or modularized system are well known. Yet after so much time and efforts, the field seems unable to come up with solutions that make a clear difference in practice. Recently, some researchers started to question whether some basic assumptions of the field were not overrated. The...
In this talk we will first review our research program that led to the paper which has been designated the most influential paper from WCRE 1999. The paper discussed a wide variety of aspects to be considered when clustering software, including formal and nonformal descriptive features, the types of links, the similarity metrics, the clustering algorithms themselves, as well as criteria to evaluation...
Software architecture erosion is a general problem in legacy software. To fight this trend, component models and languages are designed to try to make explicit, and automatically enforceable, the architectural decisions in terms of components, interfaces, and allowed communication channels between component interfaces. To help maintainers work on existing object-oriented systems, we explore the possibility...
