ORC is an ontology reasoning component that builds upon existing ontology modelling tools and techniques to support the integration and interpretation of multimodal medical information. We show how to embed ORC as a reasoning capability in reactive infrastructure agents that support intelligent agents operating in COMMODITY12, a personal health environment(More)
