  • Photovoice as a critical reflection methodology for a service learning module 
    Jordaan, Martina; Pieterse, Vreda (Higher Education South Africa, 2020-07)
    The article examines the value of using photovoice to assist reflection in a service learning module. Students were required to complete a reflective assignment in order to facilitate critical reflection on experiences ...
  • Improving short text classification through global augmentation methods 
    Marivate, Vukosi; Sefara, Tshephisho (Springer, 2020-08)
    We study the effect of different approaches to text augmentation. To do this we use three datasets that include social media and formal text in the form of news articles. Our goal is to provide insights for practitioners ...
  • Three-valued bounded model checking with cause-guided abstraction refinement 
    Timm, Nils; Gruner, Stefan (Elsevier, 2019-04)
    We present a technique for verifying concurrent software systems via SAT-based three-valued bounded model checking. It is based on a direct transfer of the system to be analysed and a temporal logic property into a ...
  • Diverging deep learning cognitive computing techniques into cyber forensics
