Abstract

Online social network is becoming more and more popular these days. Some literatures about it have been published, but few papers talk about Sin a Weibo, which is the most prevalent micro log in China and has more than 100 million users. The goal of this paper is to study the topological characteristics of Sin a Weibo and show what people use Sin a Weibo for. There are two main researches in micro logging system: (i) How is the overlay formed, and (ii) How does the information transmit. We crawled the Sin a micro log for one month and got 1.12 million user profiles. We mainly study the topology of Sin a micro log, and find that: (1) the overlay of Weibo is dynamic, (2) most of the links between users are one-way, (3) there is a core network in Sin a Weibo, and (4) the radius of Sine Weibo is very short, which make it different from human social networks and other online social networks. Finally, we classify online social networks into two types according to our results. To the best of our knowledge this work is the first quantitative study on the topological characteristics of Sin a Weibo, and the results can make people know Sin a Weibo clearly.

新浪微博:信息驱动的在线社交网络

在线社交网络现在变得越来越流行。关于它的一些文献已经发表，但很少有论文谈到新浪微博，这是中国最流行的微博，拥有超过1亿的用户。本文的目的是研究新浪微博的拓扑特征，展示人们使用新浪微博的目的。微测井系统主要有两个方面的研究:(1)叠层是如何形成的;(2)信息是如何传递的。我们在新浪微博上爬行了一个月，获得了112万用户资料。我们主要研究了Sin a微博的拓扑结构，发现:(1)微博的叠加是动态的;(2)用户之间的大部分链接是单向的;(3)Sin a微博存在一个核心网络;(4)Sin a微博的半径很短，不同于人类社交网络和其他在线社交网络。最后，根据我们的研究结果，我们将在线社交网络分为两类。据我们所知，这项工作是第一次对新浪微博的拓扑特征进行定量研究，其结果可以让人们清楚地了解新浪微博。
