摘　　要：随着互联网的高速发展和移动终端设备的快速普及,传统服务流程向高实时、高可靠性的移动式服务组合方向发展。但由于网络地址呈爆发式增长,亟需IPv6技术来解决IPv4面临的地址短缺的问题。考虑到移动网络的服务资源位置变动性、网络连接的高频率不稳定性、服务资源的受限性会直接影响服务流程质量,研究支持移动环境的服务流程不确定性评估推荐方法,尤其是在IPv6环境下部署服务和组合服务,提出面向数据感知的移动服务流程服务质量描述方法。首先,从数据感知角度对服务流程的数据进行建模,定义不同结构的服务流程模型的非功能性性质计算方法。其次,基于皮尔逊相关系数计算用户与用户之间的关联度,改进天际线方法对服务流程推荐结果进行优选。再次,基于用户评分设置非功能性参数,提出服务流程非功能性归一化计算公式,从而实现推荐Top-k个服务流程。最后,结合实验分析证明该方法的可行性。With the development of internet and the popularization of mobile equipment,the traditional service process has been developing towards to the direction of high real-time and reliability.However,due to the explosive growth of network addresses,IPv6 technology is urgently needed to solve the current shortage problem of IPv4 addresses.Considering the position variability,high frequency instability,and service resource constrained,the recommendation method focusing on the uncertainty evaluation,especially deploying services and composting services under the environment of IPv6 environment were studied,data-aware oriented mobile service process and QoS description method were proposed.First,the data model of service process was formalized,defining the non-functional properties for different structures of service process.Second,the relationship between users and users is calculated based on Pearson correlation coefficient,and the recommendation results of service process are optimized by improving the Skyline method.Third,the non-functional parameters are set according to user ratings,and the normalization calculation formula for service process is proposed to return Top-k service processes.Finally,the results of a series of experiments show that the method is feasible.
