Recommendation service for smart space-based personalized healthcare system

The paper describes architecture of a recommendation service that provides advice on how to change the lifestyle to prevent appearance or progression of cardiovascular deceases. The service is an extension of the personalized healthcare system that has access to measurements of vital signs and the patient's electronic health record. The system is designed according to the smart spaces approach and implemented on top of the Smart-M3 platform. The paper presents the ontology used for representation of data of an electronic health record and the procedure of its retrieval with subsequent generation of sensible recommendations with the use of the rules engine. Justification of usefulness of the proposed approach is illustrated by implementation of several instructions from the seventh report of the Joint National Committee on prevention, detection, evaluation, and treatment of high blood pressure as rules for the recommendation service.
