Abstract: Study on the clinical medical knowledge engineering, aims to build a large-scale, shared, reusable medical knowledge base, so as to provide the intelligent expert system of medicine, medical information retrieval system, medical education, medical natural language understanding etc.. In this paper, based on ontology integration technology, proposes an ontology integration of clinical medical knowledge management and computer-aided diagnosis system framework based on distributed ontology integration, and the technologies related to the knowledge management system is researched deeply, proposes a distributed ontology integration method based on semantics, in order to solve the information can not be shared between distributed information the distribution system and the problem of ontology integration, build a semantic platform can share the definition, design distributed ontology integration adapter, a reduction algorithm was proposed for distributed ontology integration relation, the ontology integration, reduce the redundant relation integrated ontology language, improving the quality and efficiency of ontology integration.

Abstract: Aiming at the existing of a large number of distributed and heterogeneous application systems cross-application of rights management issues, the deficiencies of traditional rights management system, which in the aspect of the formal semantics supporting and reasoning abilities, are analyzed. In the rights management of cross-applications, the concept of domain ontology is introduced; a rights management system model is presented, which is based on the domain ontology cross-applications, for permission ontology to conduct a conceptual modeling and formal description of semantics, an increase of semantic reasoning ability, rich in the corresponding access control mechanisms to provide a user-friendly structure interface.
