摘要

Retweet is an information dissemination mechanism provided by microblogging, in which users can follow with their interesting microblogs, and then forward them to their own platform to share with fans, so retweet is the most important function of information dissemination. In microblogging network there are different types of social ties. In this paper, it firstly extracts some features to identify different types of social ties, such as homogeneity, micro network struc-ture, geographic distance, and user gender. Secondly, it takes Log-linear model to fit the features. Finally, based on these coefficients, it analyzes the underlying reasons of user retweet behavior.%转发是微博提供的一个信息传播的机制，用户能够将关注者发布的有趣微博转发到自身平台，然后分享给追随者，是微博网络中信息传播最重要的功能。对于微博网络存在的不同类型连接关系，首先提取出相关特征，如同质性、微网络结构、地理距离以及用户性别等，用于识别连接关系的不同类型，然后采用Log-linear模型来拟合各个特征间系数，基于这些系数对微博用户转发行为形成的内在原因进行了分析。
