基于语义的访问控制模型及其推理机制

对语义Web上资源进行访问要求授权决策充分考虑实体之间的语义关系，但传统的访问控制模型不能处理该问题。结合基于本体的语义描述技术和基于语义规则的推理机制，将不同的语义内部关系归纳为包含关系，提出一种面向语义Web的基于语义的访问控制模型，研究其语义授权推理机制，并提出一个推理实现系统。

Semantic-Based Access Control Model and Its Reasoning Mechanism

Access to resources on the semantic Web demands the access decision take into account the semantic relationships among entities under this environment, but traditional access control models fail to address this problem. By combining Semantic Web Rule Language(SWRL) rule and Web Ontology Language(OWL) ontology, and reducing different semantic interrelations to the subsumption relation, a Semantic-Based Access Control(SBAC) model for semantic Web is presented, and its semantic authorization inference mechanism is discussed. A reasoning system for implementing the SBAC model is proposed.
