摘要
文章在前期调研的基础上,从当前社会化网络服务中用户建立关系的方式入手,提出了用户关系网络的构建机理和仿真演化原则,进而从用户关系网络拓扑结构和指数增长两个方面,分别构建仿真模型,进行仿真实验,得出了其幂律分布特征和小世界效应等仿真结果,并阐述了其在服务中的作用。
Based on the prophase investigation, starting with the pattern of users relationship establishment in cur- rent social networking service, this article proposed the mechanism of users relationship establishment and its principle of evaluation for simulation. Furthermore, from the aspects of topological structure and exponential growth, the simulation model of users relationship network was built, and the simulation experiment was conducted. Finally, the power - law distribution and the small - world effect was achieved which is the guidance for network service under social networking environment.
