We are happy to announce that our article  "What really changes when developers intend to improve their source code: a commit-level study of static metric value and static analysis warning changes" is published online in the Journal of Empirical Software Engineering, with the print version expected to appear in March 2023. In the article, we leverage the intent of developers about what constitutes a quality improvement in their own code base and investigate the improvements impact on 14 static source code metrics. In this study, we used a data set of 125,482 commits which we generated from a deep learning model that was trained from a randomized sample of 2.533 commits from 54 Java open source for which we manually labeled the commit intent.

Practical Course on Agile Software Development during the semester break

19.07.2022
During the semester break, our research group will offer a practical course on agile software development. In this course, students will learn about selected agile software development methods and practices and apply them in dedicated projects with the help of selected tools. The participants will be learning and applying their knowledge on three levels, including processes and practices, project-specific domain knowledge, implementation- and tool-specific aspects.Depending on the specific software projects, the students will get familiar with various state-of-the-art technologies and tools for software engineering and for the realisation of the specific project. The course will offer an insight into real-world software development, as well as other relevant aspects such as self learning, team work, and problem solving.

Paper accepted by SoSyM

11.07.2022
We are happy to announce that our paper "MoDMaCAO: A model-driven framework for the design, validation and configuration management of cloud applications based on OCCI" was recently accepted by the Software and Systems Modeling journal. The paper is a joint work of our group members Fabian Korte, Johannes Erbel, and Jens Grabowski with the researchers Philippe Merle, Stéphanie Challita, and Faiez Zalila from INRIA. In the paper, a model-driven framework is presented that extends the OCCI standard to support the management of platform elements on top of infrastructural resources using configuration management script. Hereby, we defined a framework to support the design, validation and management of cloud applications by utilizing the uniform interface and data model of OCCI.

Article published at IST

We are happy to announce that our article Facilitating the Co-Evolution of Semantic Descriptions in Standards and Models is published online in the Journal on Information and Software Technology, with the print version expected to appear in March 2022. The article is an extended version of a paper with the same title that was initially presented at the 12th System Analysis and Modelling Conference (SAM 2020) co-located with the ACM / IEEE 23nd International Conference on Model Driven Engineering Languages and Systems (MODELS 2020). The article describes an extension of the original methodology to make use of statistical and visual analyses of terms used in standardised specifications. The underlying meta-model for the information extracted from the specifications is also extended to accommodate the capturing of additional semantic information. With the help of the extended methodology and meta-model, we explore new means to identify further opportunities for the alignment and consolidation of semantic descriptions within identically named attributes in different information elements and specifications.The article is freely accessible for 50 days on the Journal's website.
