One argument in the discussion about the adoption of UML in industry is the supposedly large effort it takes to do modeling. Our study explores how the creation of UML models can be understood to consist of different cognitive activities: (i) designing: thinking about the design (ideation, key-design decision making), (ii) notation expression: expressing a design in a modeling notation and (iii) layouting:...
Context: Open Source is getting more and more collaborative with industry. At the same time, modeling is today playing a crucial role in development of, e.g., safety critical software. Goal: However, there is a lack of research about the use of modeling in Open Source. Our goal is to shed some light into the motivation and benefits of the use of modeling and its use within project teams. Method: In...
The Unified Modeling Language (UML) is widely taught in academia and has good acceptance in industry. However, there is not an ample dataset of UML diagrams publicly available. Our aim is to offer a dataset of UML files, together with meta-data of the software projects where the UML files belong to. Therefore, we have systematically mined over 12 million GitHub projects to find UML files in them....
This paper aims to reveal the most common strategies students use to create class designs. We show our approach of logging students' modelling activities while doing a software design task. We developed our own online modelling editor 'Web UML' and visualisation tool 'Log Viz' for the logging and interpretation of the log files. As follow-up students filled-in a brief questionnaire targeting their...
In this paper, we report on a machine learning approach to condensing class diagrams. The goal of the algorithm is to learn to identify what classes are most relevant to include in the diagram, as opposed to full reverse engineering of all classes. This paper focuses on building a classifier that is based on the names of classes in addition to design metrics, and we compare to earlier work that is...
Graphical modelling of various aspects of software and systems is a common part of software development. UML is the de-facto standard for various types of software models. To be able to research UML, academia needs to have a corpus of UML models. For building such a database, an automated system that has the ability to classify UML class diagram images would be very beneficial, since a large portion...
