摘　　要：近年来,Web服务数量不断增多,在满足用户需求的同时,用户常常为服务查准率和服务发现效率不高困扰。为进一步提高服务组合发现的效率和精度,提出一种基于服务组合簇集的多用户Web服务发现方法。构建Web服务集合的逻辑Petri网形式化模型;基于LPN可达性分析技术构建服务组合库,基于五维坐标系构建服务组合簇集;考虑Web服务调用并发数给出基于语义相似度计算的面向多用户的服务组合发现方法。通过搭建仿真实验环境、数据测试及分析比较,验证了该方法在提高服务查准率和服务发现效率上具有优越性。In recent years,the number of Web services is increasing.Users are often frustrated by the low precision rate and efficiency of service discovery.To improve the efficiency and precision of service discovery,a Web service discovery method based on service composition clusters was proposed.The LPN model of Web service set and the service composition library were constructed.The service composition cluster set was constructed based on five-dimensional coordinate system.A multi-user service composition discovery method based on semantic similarity computation was proposed.Moreover,the validity and superiority of proposed methods were illustrated by simulation experiment and comparative analysis.
