中文摘要: 随着新兴在线社交网络服务的大规模涌现,具有不同结构与功能的社交网络之间呈现交互耦合的发展趋势,形成多层耦合的复杂社交网络。本课题对在线社交网络进行实证分析,研究社交网络拓扑演化机制,建立耦合网络拓扑演化模型。研究耦合社交网络环境下的信息传播过程,提出耦合社交网络信息传播模型,分析耦合网络结构对信息传播过程的影响,揭示影响信息传播过程的关键因素。在此基础上,设计社交网络信息传播干预策略。主要创新工作:1)研究建立能够描述复杂社交网络的形成过程的双层耦合网络拓扑演化模型;2)提炼双层耦合社交网络的信息传播模式,设计考虑外部网络舆论场影响率的社交网络信息传播模型,明确耦合网络结构对信息传播过程的影响;3)利用耦合网络的信息传播规律,设计基于覆盖网络的社交网络信息传播干预策略。研究成果有助于对在线社交网络信息传播规律形成深刻认识,为网络营销和舆情监控等网络应用提供理论指导和方法借鉴。

英文摘要: With the large-scale emergence of online social network services, the online social networks with different structures and functions present interaction coupled trend and it forms the multilayer coupled complex social network gradually. This project will make empirical analysis on the online social networks ,research on the topology evolution mechanism of the coupled online social networks and establish the double-layer coupled network evolution model. The information dissemination process is studied in the coupled social networks environment. The reasonable information dissemination model is proposed. By analyzing the topology's influence on the information transmission of social network, the key factors that effect information transmission process is revealed. On this basis can we design the intervention strategy of the network information dissemination. The main innovation of the project is as follows. Firstly,the network topology evolution model is established, and this model can describe the structural features of the social networks accurately. Secondly, the information dissemination mode is refined. Considering the influence ratio, the information dissemination model is designed, which based on the information dissemination mode of the coupled social network. To make sure the network topology's impact on
