This week Agnieszka Ławrynowicz and Jędrzej Potoniec have been visiting the Protégé team at the Stanford Center for Biomedical Research (BMIR) (Stanford University). Agnieszka Ławrynowicz gave a talk entitled “Pattern discovery in semantic data mining” at the Protégé Research Meeting. The talk described Fr-ONT-Qu algorithm for mining patterns from Semantic Web data, and discussed its application in two use cases including our ongoing work on re-using Fr-ONT-Qu inside a LeoLOD Protégé plugin.

We thank a lot for the warm welcome, especially we thank Tania Tudorache for being a great host.

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.

dr Claudia d’Amato from the University of Bari has been visiting the Institute of Computing Science of PUT for one week exchange within LeoLOD.

Edit: We worked together on the DMOP ontology, and as an effect, together with the other collaborators we have prepared a paper that is currently under review.
