摘　　要：为解决多Agent系统在动态分布式环境中的交互缺乏语义信息的问题,并加强对隐私和安全方面的要求,将语义Web技术中的OWL DL和规则引入到Linda协同模型中,提出一种基于语义和策略的协同模型。该模型在Linda协同原语的基础上提出4个对语义元组空间操作的原语,并加入访问策略、定义访问策略原语,使该模型能够满足开放动态的分布式系统对安全、隐私以及可扩展性诸多方面的要求。实验结果表明,该方法可以使Agent在交互中使用更少的时间获取更多、更精确的信息,提高了Agent交互效率。In dynamic and distributed systems,to solve the lack of semantic problem and strengthen the privacy and security in multi agent system（MAS）,OWL DL and rule are introduced into Linda and a coordination model based on semantic and access policy is pre-sented.Four new coordination primitives are defined.Furthermore,to cope with the requirements of security,privacy,and scalability arising in open and dynamic distributed systems,access policy is introduced to the model.Experiments show that,the proposed method can make agents query more accurate information in less time,and the agents interaction efficiency is improved.
