【摘要】 社交网络在某种程度上改变了人们的网络行为方式,社交网络平台业已成为人们信息交流和信息传播的中心,这在微博、微信上表现的尤为显著,网络集群行为就是在这样的环境下产生的。网络集群行为是众多的网民在网络上的、自发的、无组织的围绕一个公共议题,发表自己的意见并进行传播的行为,而网络集群性事件是网络集群行为导致的一个社会性事件,因此,研究网络集群行为及其演化规律具有重要的理论和现实意义。首先,本文对网络集群行为、网络集群性事件的界定和关系进行了分析,得到网络集群行为产生的关键因素因素,并分析了关键因素对个体行为的影响。运用案例分析的研究方法对网络集群行为演化过程进行了探讨,得到网络集群行为演化的四个阶段,并对网络集群行为演化的影响因素进行分析。其次,阐述了运用系统动力学理论建模的优势和可行性和运用系统动力学方法建模的步骤,通过确定的研究条件设置以及研究边界,给出了系统的因果关系图,以因果关系图绘制出系统总流图,并对系统总流图中的变量进行了定义分析,再通过函数确定变量的方程式,完成变量的赋值和模型建立,然后运用历史检验法对模型有效性进行了验证。最后,基于建立的网络集群行为演化模型,运用VENSIM软件对网络集群行为演化过程进行仿真,并对仿真结果从网民、政府、媒体、事件这四个方面提出相应的策略。更多还原

【Abstract】 The social network has changed the way people’s network behavior to a certain extent,the social network platform has become the people to exchange information and information dissemination center,which is reflected in the micro-blog,WeChat is particularly significant,the network cluster behavior is produced in such environment.The network collectivebehavior is a large number of Internet users in the network,spontaneous and unorganized around a public topic,to express their views and communication behavior,and the network cluster events are leading the network collective behavior of a social event,therefore,it has important theoretical and practical significance to research the network cluster behavior and evolution.First of all,this paper focuses on the network cluster behavior,network cluster events defined and analyzed the relationship between the factors are key factors to produce network cluster behavior,and analyzed the influence of key factors on individual behavior.By using the method of case study,the evolution process of network cluster behavior is discussed,and the four stages of network cluster behavior evolution are obtained,and the influence factors of network cluster behavior evolution are analyzed.Secondly,this paper expounds the advantages and feasibility of using system dynamics and modeling method of system dynamics steps,through the research on boundary conditions to determine the settings and research,given the causality diagram,drawing to the causal relationship between the total system flow chart,and the total system flow diagram in the analysis of variables are defined then,the variable equation is determined by function,establish the variable assignment and model,and then use the method of historical test the validity of the model is verified.Finally,the establishment of the network cluster behavior evolution model based on the evolution of the network cluster behavior using VENSIM software process simulation,and the simulation results from Internet users,government,media,events of the four aspects put forward the corresponding strategy.更多还原
