An Information Exchange Model Based on HL7 v3 and Ontology in the Public Health Emergency Alarm System

Information exchange plays a vital part in the success of public health emergency alarm system. It includes collecting and integrating the monitoring information, sharing of data, commanding coordinately and so on. An information exchange model based on HL7 v3 and ontology is proposed in this paper. It adopts HL7 v3 and ontology techniques to tackle the problem caused by structural and semantic heterogeneities respectively. This approach promises a system capable of overcoming difficulties encountered by traditional information exchange in the public health emergency alarm system.
