On December 6, 2022, the 35th EPILOG of TU Wien Informatics took place. The most outstanding researchers and their scientific work are presented and awarded as part of this biannual event. Researcher Bernhard Pointner, who wrote a significant portion of his master's thesis in our Visual Analytics Group, was one of the three nominees of the Distinguished Young Alumn Award presenting their master's theses to the broader public during the EPILOG final. Bernhard Pointner was subsequently awarded an honorable mention for his work and presentation.
In his master's thesis, "An Interactive Visualization Approach to Tackle Design Constraints in a Rule-Based Recommendation System," Bernhard Pointer, under the supervision of Johanna Schmidt (VRVis) and Silvia Miksch (TU Wien), set himself the task of making visualizing recommendations systems more understandable for the user. Visualization recommendation systems are designed to suggest the most suited visualizations based on existing data. However, the decision-making of these systems, which rely on many complex exceptions and rules, is very difficult to understand. To create greater traceability and, at the same time, trustworthiness in the recommendation system, Bernhard Pointer has developed a visualization method based on the "Draco" visualization recommendation system, with which the entirety of all rules, also called knowledge base, can better be displayed. The new system allows following the system's decisions visually and a better understanding of the different connections of the respective rules.
