Objectives: To meet the challenge for high quality and efficient care, highly specialized and distributed healthcare establishments have to communicate and co-operate in a semantically interoperable way. Information and communication technology must be open, flexible, scalable, knowledge-based and service-oriented as well as secure and safe. Methods: For enabling semantic interoperability, a un...

The issue of semantic interoperability pervades distributed systems whose components are designed independently. For example, when a source intends 70 to mean “70 meters, with 20% error”, the receiver must not interpret the result as “70 feet, exactly”. We examine semantic interoperability problems in a distributed object management environment, i.e., for a system of distributed objects and ser...

G. Vetere M. Lenzerini Although service-oriented architectures go a long way toward providing interoperability in distributed, heterogeneous environments, managing semantic differences in such environments remains a challenge. We give an overview of the issue of semantic interoperability (integration), provide a semantic characterization of services, and discuss the role of ontologies. Then we ...

This paper discusses the issue of information interoperability. In view of the problems that it is difficult to solve the semantic conflicts in information interoperability, the paper shows how to build the extension ontology model for information interoperability based on Extenics information-knowledge-Strategy system. Take advantage of Extenics’ feature of contradiction problem solving, the e...

Objectives: In the field of open Electronic Health Records (EHRs), openEHR as an archetype-based approach is being increasingly recognised. It is the objective of this paper to shortly describe this approach, and to analyse how openEHR archetypes impact on health professionals and semantic interoperability. Methods: Analysis of current approaches to EHR systems, terminology and standards develo...
