基于OWL的本体访问控制模型

当前的语义网中，本体缺乏访问控制机制。这导致本体的隐私无法受到保护，最终损害了语义网的稳定性。为了实现对本体的有效保护，提出了一种基于网络本体语言的访问控制模型。该模型为本体中的类定义了访问规则和访问控制属性，并由此建立了访问控制关系。进一步研究了模型的性质使其有效地应用于本体和基于本体的推理系统的构建。分析表明，该模型能够明确地定义本体的访问控制关系，并充分应用于本体的保护。而且还可以通过灵活的扩展机制，适应语义网络中日益复杂的访问控制需求。

OWL-Based Model for Access Control of Ontology

Nowadays the ontology in the semantic web lacks the access control mechanism,it causes the loss of privacy protection for the ontology and eventually damages the stability of semantic web.To guarantee the effective protection of the ontology,a new web ontology language-based(OWL-based) model for access control is proposed.In this model,the access rules and the access control attributes are defined.The relations for the access control are set up.Features of this model are discussed in details to apply to the construction of the ontology and the ontology-based reasoning systems.It is shown that this new model can definitely demonstrate the relations for the access control and can be effectively used for the protection of the ontology.Moreover,with the flexibility and extensibility it owned,this new model also meets the increasingly complex requirements of the access control in the semantic web.
