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

    Publicado em February 27th, 2012News

    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

    Publicado em December 10th, 2011News, Publications

    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.

  • PhD research internship at UBC

    Publicado em March 16th, 2011News

    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.
