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, mobile social networks are changing the mode of people’s information exchange and sharing. Among them, WeChat, as the most popular and representative mobile social software at present, attracts many users to use WeChat to exchange and share information in real time because of its numerous functions, timeliness and socialization features. Taking WeChat’s circle of friends as the research object, this paper analyzes the characteristics and transmission mechanism of WeChat’s information dissemination. Based on this, we introduce a number of influencing factors such as user similarity, information value and information timeliness to construct a suitable communication system for explaining the information spread of WeChat friends circle Regular and improved SEIR model. The simulation results show that the improved model of information dissemination can better explain the impact of relevant factors on the spread of WeChat information.
