【摘要】：随着互联网的快速发展，特别是Web2.0的迅速兴起，涌现出大量具有不同目的和范畴的在线社交网络应用，如博客、微博和社交网站等。社交网络应用在近几年得到迅速发展，逐渐成为大家收集传播信息、表达观点和人际交往不可或缺的媒介工具。然而，社交网络的负面影响也不容忽视，谣言、诽谤信息肆意传播，给社会造成不良影响甚至影响社会秩序。为充分发挥社交网络在信息传播方面的积极作用，推动社交网络的健康发展，本文研究在线社交网络的信息传播理论，建立社交网络信息传播模型，探索社交网络的信息传播规律。目前，随着新兴社交网络服务的大规模涌现，社交网络环境日趋复杂，面向不同应用领域的社交网络应用之间呈现交互的发展趋势。为了认识这种复杂社交网络环境下的信息传播过程，本文从网络层次性的视角开展社交网络信息传播建模研究，，主要工作如下：针对特定的社交网络应用，分析其信息传播过程，提炼信息传播机制。在传染病模型(SEIR模型)的基础上，引入信息价值，定义用户信息传播状态，构建了能够描述单个社交网络(单层网络)信息传播过程的信息传播模型（S-SEIR）。实验结果表明该模型能够反映在线社交网络的信息传播规律，特别是通过模型分析得出信息价值是影响社交网络信息传播过程中的重要因素。在S-SEIR模型的基础上，分析多种社交网络应用共存环境下(双层网络)的信息传播过程，通过定义外部舆论场，分析不同用户行为（关注、评论、站内转发和站间转发等）对信息传播的影响，设计了双层社交网络信息传播模型O-SEI_2R。通过对该模型进行仿真，结果表明不同社交网络应用间的协作或抑制关系能够影响社交网络信息传播过程。最后，从信息内容、信息传播途径、信息主体、信息环境四个方面探讨了社交网络信息传播控制与干预策略。这些研究成果可以为人们认识在线社交网络信息传播规律，建立社交网络信息传播控制机制提供理论和方法支撑。
[Abstract]:With the rapid development of the Internet, especially the rapid rise of Web2.0, a large number of online social network applications, such as blog, Weibo and social network, have emerged. The application of social networks has developed rapidly in recent years, and has become an indispensable media tool for people to collect and disseminate information, express their views and communicate with each other. However, the negative impact of social networks can not be ignored, rumors, defamation information wanton spread to the society, and even affect the social order. In order to give full play to the positive role of social network in information dissemination and promote the healthy development of social network, this paper studies the information dissemination theory of online social network and establishes the information dissemination model of social network. Explore the laws of information dissemination on social networks. At present, with the emergence of new social network services, the social network environment is becoming more and more complex. In order to understand the process of information dissemination in this complex social network environment, this paper studies the modeling of social network information dissemination from the perspective of network hierarchy. The main work is as follows: For specific social network applications, the process of information dissemination is analyzed, and the mechanism of information dissemination is refined. Based on the model of infectious diseases (SEIR), this paper introduces the value of information, defines the state of information transmission of users, and constructs a model of information dissemination which can describe the process of information dissemination in a single social network (single-layer network). The experimental results show that the model can reflect the information transmission law of online social network, especially the information value is an important factor in the process of social network information dissemination. On the basis of S-SEIR model, this paper analyzes the process of information dissemination in the coexistence environment of social network applications (two-layer network). By defining the external public opinion field, it analyzes different user behaviors (concern, comment, etc. The influence of intra-station forwarding and inter-station forwarding on information dissemination is discussed. A two-layer social network information dissemination model O-SEI _ 2R is designed. The simulation results show that the collaboration or inhibition relationship among different social network applications can affect the process of social network information dissemination. Finally, the control and intervention strategies of social network information dissemination are discussed from four aspects: information content, information dissemination approach, information subject and information environment. These research results can provide theoretical and methodological support for people to understand the rules of online social network information dissemination and establish social network information dissemination control mechanism.
