摘要
随着移动互联技术的发展,移动社交网络正改变着人们进行信息交流与共享的模式。其中,微信作为当前最流行的、具有一定代表性的移动社交软件,其众多功能和及时性、社交化的特点,吸引众多用户运用微信进行信息的实时交流和共享。以微信朋友圈为研究对象,分析了微信的信息传播特点与传播机制,在此基础上,引入用户相似度、信息价值和信息时效性等影响因素构建了一种适用于解释微信朋友圈信息传播规律的改进的SEIR信息传播的系统动力学模型,仿真实验表明该改进的信息传播模型能较好解释相关影响因素对微信信息传播的影响。
With the development of mobile internet technology and the rise of mobile social network, the mode of people＇ s exchanging and sharing information is changing. With its features of muhifunctionality, timeliness and sociability, the WeChat, as the most popular instant messaging social software, promotes people＇ s real-time information communication. This paper , takes circle of friends as the research object, analysises the information transmission characteristics and mechanism of the WeChat. Based on that, through introducing three new factors of user similarity, information value and information timeliness, an improved SEIR system dynamics model is built to explain some laws of information transmission of the WeChat. The simulation experiments shows the improved SEIR model can better explain the influence of the related factores on the information dissemination of the WeChat.
