摘要由于互联网应用的普及和移动终端设备应用的发展,社会网络的服务人性化的增强,微博这一新型的服务模式应运而生。微博,微博客(Micro Blog)的简称,基于用户关系的信息的分享、传播和获取的平台,用户可以通过WEB、WAP等客户端组建个人社区,以140字以内的文字更新信息,并实现即时分享信息。用户既可以是信息的创造者也是消费者,通过网络平台和网络服务应用改变着网络信息的传播模式。研究微博信息的传播机制有助于了解信息在网络平台中的规律和特征。本文选取国内影响力最为深远的微博网站--新浪微博为蓝本进行建模分析,综合运用复杂网络、网络爬虫、概率论、应用统计学等相关理论为基础,研究用户的微博发布行为、评论行为和转发行为,并进行深入的统计分析。64610
