摘要
针对传统服务描述模型无法对军事信息服务中服务的使用权限、适用范围等非功能约束信息进行全面、标准化描述的问题,扩展已有web服务通用描述模型,提出了一种基于行为约束的军事信息服务描述模型,以全面支持军事信息服务功能、行为约束和服务质量的描述。在此基础上采用分层匹配思想,在服务发现过程中引入相似度和匹配算法,对行为约束的相似性进行量化计算,提出基于行为约束的服务过滤,从而提高军事信息服务发现的查准率和查询效率。通过实例分析和仿真实验证明方法的可行性和有效性。
Traditional service description model cannot completely and normally describe military information services＇ nonfunctional restrictions, such as service using right, service using scope and so on. Aimed at this problem, a behavior restriction based description method that extends the common web service description model was proposed to support the description of the functionality, behavior restrictions and QoS attributes of military information services. By adopting level based matching idea, a behavior restriction based filter method was provided. The method imported similar degree and matching arithmetic to compute the similarity of restrictions quantilicationally to improve the precision and efficiency of service discovery. Case analysis and simulation results testify the feasibility and effectiveness of the method.
