Highlights
Maria Skłodowska Curie Memorial Cancer Center and Institute of Oncology (MCMCC) based in Warsaw is a leader in cancer treatment in Poland. The best standards, advanced knowledge and experience in the treatment of the disease are concentrated there and the best doctors practice in the center. Unfortunately, other clinics in Poland do not have such high recovery rates, so we, together with the MCMCC, have developed a Clinical Decision Supporting System to systematize knowledge in oncology treatment and reduce the risk of medical error in all Polish oncology clinics. Besides, as it is compatible with OWL, a well known semantic web standard, and therefore it contributes to OWL community growth.
