    Software Evolution Analysis with Networks (SEANets) is a free to use Eclipse plugin made by the software engineering lab at the University of Macedonia, Thessaloniki, Greece. The aim is to map, multiple Java based, object oriented systems as time-evolving directed networks, where nodes correspond to classes and edges between nodes, indicate the presence of method invocations that follow the Law of Demeter. Multiple Network metrics like the diameter, edges/degree evolution and clustering coefficient are calculated based on the software's code evolution.

    JDeodorant: Identification and Removal of Type-Checking Bad Smells
    th European Conference on Software Maintenance and Reengineering CSMR Athens Greece Apr
    In this demonstration, we present an Eclipse plug-in that automatically identifies Type-Checking bad smells in Java source code, and resolves them by applying the “Replace Conditional with Polymorphism” or “Replace Type Code with State/Strategy” refactorings. To the best of our knowledge there is a lack of tools that identify Type-Checking bad smells. Moreover, none of the state-of-the-art IDEs support the refactorings that resolve such kind of bad smells.

    Investigating the effect of evolution and refactorings on feature scattering
    Springer Software Quality Journal May
    The implementation of a functional requirement is often distributed across several modules posing difficulties to software maintenance. In this paper, we attempt to quantify the extent of feature scattering and study its evolution with the passage of software versions. To this end, we trace the classes and methods involved in the implementation of a feature, apply formal approaches for studying variations across versions, measure whether feature implementation is uniformly distributed and visualize the reuse among features. Moreover, we investigate the impact of refactoring application on feature scattering in order to assess the circumstances under which a refactoring might improve the distribution of methods implementing a feature.

    Identification and Removal of Complex Method Bad Smells
    University of Macedonia Jun
    In the object-oriented design paradigm, the methods that a class consists of should be designed in order to carry out one single task. But many times during the phase of development and due to pressing time limits the design of many methods deteriorates and bad smells in code are emerging. Those bad smells include Long Methods and Complex Methods. In the first case the problem is solved by using the Extract Method Refactoring, but for the second case the Extract Method Refactoring is inapplicable. This is because methods with this bad smell have local variables that are rampant and use one another in a complex way. This is the case where Replace Method with Method Object refactoring comes to solve the problem. It transforms the com

    Investigating the Evolution of Feature Scattering
    Sixth International Workshop on Software Quality and Maintainability Szeged Hungary Mar
    The identification of software components that implement a certain feature is vital for understanding and reverse engineering an existing software system. Requirements traceability allows the investigation of scattering and tangling requirements which hinder significantly software maintenance. Even worse than feature scattering in a number of modules, is that this diffusion might deteriorate as software evolves. In this paper we attempt to shed light on the following questions: whether scattering in the requirements implementation increases over time, whether the methods implementing a specific feature are distributed unequally and whether scattering can be justified by the reuse among features at method level. Emphasis is place

    SEAgle: Effortless Software Evolution Analysis
    IEEE International Conference on Software Maintenance and Evolution Sep
    The analysis of software evolution by means of mining public repositories has been established as one of the dominant approaches for empirical studies in software engineering. However, even the investigation of the simplest research question demands a mazy process involving installation and configuration of tools, climbing their learning curve and tedious collection of desired information. Acknowledging the need for effortless querying of remote repositories we introduce a Web-based one-click approach’ to perform software evolution analysis of Git projects.

    Forecasting Java Software Evolution Trends employing Network Models
    IEEE Transactions on Software Engineering Jun
    The evolution of networks representing systems in various domains, including social networks, has been extensively studied enabling the development of growth models which govern their behavior over time. The architecture of software systems can also be naturally represented in the form of networks, whose properties change as software evolves. In this paper we attempt to model several aspects of graphs representing object-oriented software systems as they evolve over a number of versions. The goal is to develop a prediction model by considering global phenomena such as preferential attachment, past evolutionary trends such as the tendency of classes to create fewer relations as they age, as well as domain knowledge in terms of principles tha

    Identification of Refused Bequest Code Smells
    th IEEE International Conference on Software Maintenance ICSM Sep
    Accumulated technical debt can be alleviated by means of refactoring application aiming at architectural improvement. A prerequisite for wide scale refactoring application is the automated identification of the corresponding refactoring opportunities, or code smells. One of the major architectural problems that has received limited attention is the so called 'Refused Bequest' which refers to inappropriate use of inheritance in object-oriented systems. This code smell occurs when subclasses do not take advantage of the inherited behavior, implying that replacement by delegation should be used instead. In this paper we propose a technique for the identification of Refused Bequest code smells whose major novelty lies in the intentional introdu

    A Taxonomy of Evaluation Approaches in Software Engineering
    Balkan Conference in Informatics Best Paper Award Sep
    As in any academic discipline, the evaluation of proposed methodologies and techniques is of vital importance for assessing the validity of novel ideas or findings in Software Engineering. Over the years, a large number of evaluation approaches have been employed, some of them drawn from other domains and other particularly developed for the needs of software engineering related research. In this paper we present the results of a survey of evaluation techniques that have been utilized in research papers that appeared in three leading software engineering journal and propose a taxonomy of evaluation approaches which might be helpful towards the organization of knowledge regarding the different strategies for the validation of research outcom
