  14. 3. Ontologyand Health Application

  15. Why do weneedOntologiesin healthcareAplication? REPRESENTING INFORMATION • An ontology is a "formal, explicit specification of a shared conceptualisation". • It formally represents knowledge as a set of concepts within a domain, and the relationships between theses concepts. • It can be used to model a domain and support reasoning about concepts REAL INFORMATION Semantic INTEROPERABILITY Problem

  16. Why do weneedOntologiesin healthcareAplication? • PROBLEM: Data integrationwithdiferent standards • AHA/MIT-BIH (Physionet) • SCP-ECG (ISO/DIS 11073-91064) • HL7 aECG ELECTROCARDIOGRAM
