中文摘要：
考虑到当前的服务推荐策略大多缺乏对系统整体发展需求的关注,结合服务新增、失效等动态要素构建了服务生态系统仿真模型;从全局发展的视角出发,提出了服务系统综合发展指标体系;结合服务系统模型和综合发展指标体系,设计了能够保障系统中服务多样性、减小服务失效率的推荐策略,该策略将服务分为新服务、保护服务和普通服务并分别设计推荐机制;在基于实际数据构建的仿真模型上进行测试,验证了推荐策略的有效性。
英文摘要：
Owing to the most of present recommendation methods were focused on users＇perspective only,a service recommendation strategy from the overall perspective was proposed based on a Web service ecosystem model with dynamic factors to consider the development and stability of the whole system.In the proposed strategy,the services were divided into the new service group,the protected service group and the normal group,and the corresponding recommendation mechanisms were design.Based on the real data,the simulation model was constructed to verify the effectiveness and efficiency of the new strategy.
