New project: Models, Techniques and Tools for Software Evolution – New Challenges

New INES project (2nd round) involves researchers from UFBA, UFCG, UFRN, UEFS and PUC-Rio.

The project “Models, Techniques and Tools for Software Evolution: New Challenges“ has as its starting point the main goal of the previous INES project (“Models, Techniques and Tools for Software Evolution“/2009-2011) — to improve our understanding of the nature software processes and their evolution,  — and also its results — a set of models, techniques and tools to help integrate development activities in the software life cycle.

INES researchers at CSMR 2012

INES researchers, working in the context of the project “Models, Techniques and Tools for Software Evolution” had 2 papers accepted at CSMR 2012:

(1) “Understanding Structural Complexity Evolution: a Quantitative Analysis”,
Antonio Terceiro, Manoel Mendonça, Christina Chavez (UFBA) and Daniela Cruzes (NTNU)

Abstract—Background: An increase in structural complexity
makes the source code of software projects more difficult to
understand, and consequently more difficult and expensive to
maintain and evolve. Knowing the factors that influence structural
complexity may help developers to avoid the effects of
higher levels of structural complexity on the maintainability of
their projects.
Aims: This paper investigates factors that might influence the
evolution of structural complexity.
Method: We analyzed the source code repositories of 5 free/open
source software projects, with commits as experimental units. For
each commit we measured the structural complexity variation it
caused, the experience of the developer who made the commit,
the size variation caused by the commit, and the change diffusion
of the commit.
Results: Change diffusion was the most influential among the factors
studied, followed by size variation and developer experience;
system growth was not necessarily associated with complexity
increase; all the factors we studied influenced at least two
projects; different projects were affected by different factors; and
the factors that influenced the increase in structural complexity
were usually not the same that influenced the decrease.
Conclusions: All the factors explored in this study should be
taken into consideration when analysing structural complexity
evolution. However, they do not fully explain the structural
complexity evolution in the studied projects: this suggests that
qualitative studies are needed in order to better understand
structural complexity evolution and identify other factors that
must be included in future quantitative analysis.

(2) “On the Relevance of Code Anomalies for Identifying Architecture Degradation Symptoms”, Isela Macia(PUC-Rio), Roberta Arcoverde(PUC-Rio), Alessandro Garcia(PUC-Rio), Christina Chavez (UFBA) and Arndt von Staa(PUC-Rio).

This work has been developed by PUC-Rio researchers,  and Christina Chavez (UFBA) co-authored it during her pos-doc at PUC-Rio.

INES at CBSOFT 2011: FEES 2011 & SBES is 25

FEES 2011

INES researchers will join the FEES 2011 @ CBSoft (São Paulo), to discuss “Free/Libre/Open Source Software Development in Software Engineering Education: Opportunities and Experiences”.

The work involves researchers from UFBA (INES project: Models, Techniques and Tools for Software Evolution) in collaboration with IME-USP. One of the reported experiences took place in a Software Evolution course at UFBA.

“Free/Libre/Open Source Software Development in Software Engineering Education: Opportunities and Experiences”

– Christina Chavez, Antonio Terceiro (UFBA); Paulo Meirelles, Carlos Santos Jr., Fabio Kon (IME-USP)

PhD research internship at UBC

PhD student Antonio Soares de Azevedo Terceiro (DMCC-UFBA), member of the project “Models, Techniques and Tools for Software Evolution”, will undertake a PhD research internship in Empirical Software Engineering at the Software Practices Lab, Department of Computer Science at UBC (University of British Columbia) from March to September, 2011, and will be supervised by professor Gail C. Murphy.

Professor Gail Murphy’s team has been working on the concept of Degree of Knowledge over source code elements. In his PhD, Antonio Terceiro investigates the influence of developer characteristics over the
evolution of source code structural complexity in free software projects. In this research internship, Degree of Knowledge over source code elements will be considered as one of the factors that may influence the variation in structural complexity, what will be investigated in a empirical study.

UFBA researcher visits UFCG

Christina Chavez (LES-UFBA) visits UFCG researchers from November 30 to December 1st, 2011, to discuss ongoing research in the context of the project “Models, Techniques and Tools for Software Evolution”.
