I am currently working on the evolution of ontologies and knowledge graphs and how evolution affects downstream tasks. This project is called CHIMP. So far, I have focused on the logical entailment (materialization) and embeddings. My research also includes ontology feature extraction used in the prediction of the impact. Thanks to a master student, my research is also integrated into a Protégé Plugin, which visualizes changes for ontology engineers, while they are editing an ontology.
Further, I am also interested in stream processing. I have previously worked on a platform that enables the combination and analysis of heterogeneous data streams in one system.
Open topics for students can be found on the topic's site.
