基于约束条件的战场信息服务匹配算法

Restriction based battlefield information services matching algorithm

针对现有服务描述模型不能全面、准确地描述战场态势信息服务中地理范围、环境类型、目标属性等非功能属性的问题,扩展现有Web服务通用描述模型,提出了一种基于约束条件的战场态势信息服务描述模型,以支持战场态势信息服务功能、非功能描述。在此基础上提出一种基于约束条件的服务匹配算法,通过对强、弱约束条件进行相似度量化计算,进一步筛选满足用户需求服务,提高匹配精度。理论分析及仿真表明该算法提高了语义服务匹配的查准率和查询效率。

Traditional service description model cannot completely and normally describe military information service＇ nonfunctional restriction, such as geographical scope, type of environment, and target property. Aiming at this problem, restriction specification was introduced in service description that extends the common Web service description model. On this basis, a muki-granularity matching algorithm was provided. The proposed algorithm filtered out the unmatched service by calculating the similarity of soft and hard restriction, which enhanced the precision of matching. Case analysis and simulation results testify the feasibility and effectiveness of the algorithm.
