Ontologies in Medical Knowledge Representation

In this work structure of medical ontologies and their construction process are presented. For each medical domain one has to specify the scope of the ontology, acquire medical knowledge, select a tool and an ontology language, design the ontology, and present it in an appropriate way. Special attention is devoted to the problem of representing relevant medical knowledge in the form of ontology. Connection of an ontology with a rule base as a part of a decision support system is established. The ontology of the heart failure disorder, designed for the use in Heartfaid platform, is used to explain the ontology construction process.
