Last week, our colleague Romana Pernischova presented her paper titled ‘ChImp: Visualizing Ontology Changes and their Impact in Protégé’ at the workshop VOILA, colocated with ISWC 2020. Together with Mirko Serbak, Daniele Dell’Aglio, and Abraham Bernstein, she looked at the needs of ontology engineers and created Protege plugin ChImp to help visualize changes and their impact while editing ontologies. Because of COVID-19, the conference took place online. Luckily, her presentation was still a success and well received. The paper can be found here.

At the same conference, a group of DDIS members also presented a demo of a graph-based retrieval system for lifelogs. ‘LifeGraph’ was developed in the context of an international evaluation campaign which, due to some changes and delays caused by the pandemic, was held online only a week before ISWC. During the demo, conference attendees could get an impression of how such a graph exploration-based approach could be used to find particular events from the life of a lifelogger. The demo was nominated for ‘Best Demo’. More information on the inner workings of that approach can be found in the paper, authored by Luca Rossetto, Matthias Baumgartner, Narges Ashena, Florian Ruosch, Romana Pernisch, and Abraham Bernstein.
