介绍了通过建立信息源本体间的语义关联来支持信息源间的语义互操作的OSIS(Ontology-based information Source Interoperation System),描述了基于连接的本体合成代数系统及基本代数运算的特点,并通过连接函数(建立本体语义关联的函数)建立语义关联的过程。
To describe and integrate various policies applied in different domains, the definition of the family of OntoRBAC based on the ontology of a general role-based access control （RBAC） policy is proposed, which can support and extend the RBAC96 model. The uniform ontology-based description mechanism of secure policies is applied in OntoRBAC, which can be used to describe different secure policies in distributed systems and integrate policies in semantic level with upper concepts. In addition, some rules have been defined to reason within the OntoRBAC to extend the inference algorithms in ontology, which makes the system accommodate itself to RBAC policies better.
