中文摘要: 本项目拟采用统计物理、复杂网络理论和非线性动力学方法,利用新浪微博等多个在线社会网络上的信息传播数据,分析在线社会网络和信息传播网络的结构、演化规律及其相互作用关系,挖掘信息传播过程中的个体行为规律和交互行为特征,揭示其中的标度率和普适性,提炼出影响信息传播的微观机制;结合数据本质特征和传播机理分析,进行个体计算实验建模,并基于实证数据的宏观涌现特征和演化规律提出模型校准方法,从而更深入地理解在线社会网络上的信息传播机制;基于"情景-应对"研究思想,针对社会网络上的谣言扩散等舆情防控问题和产品信息发布问题设计计算实验,得到特定情景下的信息传播过程的模拟和预测,分析并提炼出相应社会问题可能的应对措施。本项目的研究将深化人们对社会网络演化机制和信息传播动力学的理解,对解决信息传播相关社会问题有进一步的推动意义。

英文摘要: Using the theories and methods from statistical physics, complexity science and complex networks, we will research the information spreading data on the social networks such as the Sina microblog in detail. We will analyse the structure and the evolution of the online social network and the information diffusion network respectively, obtain the individuals' behaviors and interacting patterns in the information transmission process, as well as the underlying dynamic mechanisms that may affect the information dissemination. Combined the empirical results and proposed mechanisms, the computational experimental model will be constructed, and the model calibrating method based on the macroscopic law of the datasets will also be proposed. Therefore, it will help us to understand the information spreading mechanic on the social network in depth. In addition, based on the idea of "scenario-response", we will design computational experiment on some problems such as the control of public opinion and the product information dissemination on the social networks, to analyse the probable solutions of the corresponding social problem. The research will deepen our understanding of the social network evolution and the informatioin spreading dynamics, and push forward to solve the related social problems.
