Visit of Sebastian Rudolph

Last week we were happy to host prof. Sebastian Rudolph from the Technische Universität Dresden. Together with Sebastian, Jędrek Potoniec and myself we have started a cooperation in the area of knowledge base completion with Formal Concept Analysis (we investigated some new ideas related to the use of machine learning in FCA).
Sebastian also gave a very interesting talk entitled “Advocatus Diaboli – A Playful Way of Enriching Ontologies with Negative Constraints” at the seminar of the Institute of Computing Science on enriching ontologies with negative constraints with a methodology where a domain expert navigates through the space of satisfiable class expressions with the aim of finding absurd ones. These ones can then be eliminated by adding a relevant constraint to the ontology.
