RDF Schema Based Ubiquitous Healthcare Service Composition.

We suggest a service framework and algorithms of provisioning healthcare services in a ubiquitous computing environment. In order to meet customers' need we translate the need into relevant goal and repeatedly refine the goal into sub-goals through commonsense knowledge until there are appropriate services for sub-goals and after, employ the services. The results of this research enable integration and interconnection of devices, applications, and functions within the healthcare services. By RDFSs and their interoperability, a ubiquitous healthcare service composition is achieved, and the hidden semantic distances can be measured dynamically. [ABSTRACT FROM AUTHOR]
