Top SchoolPetr Křemen is a semantic architect and ontologist with 11 years of professional experience building knowledge-driven information systems and applying semantic web technologies. He combines academic rigor from a Ph.D. background and long-term research at Czech Technical University with hands-on roles as a team lead, consultant, and co-owner of a tech company. His expertise spans OWL, description logics, SNOMED-CT, linked open data and ontological reasoning, with applied work in healthcare, government open data, and research environments.
