This paper aims to quantify the correlation between social ties and checkins by investigating two location-based social networking websites. It is discovered that the probability of social or checkin’s rank is inversely proportional to the corresponding rank, which implies the potential connection between friendship and mobility. Therefore, the fractions of friends and checkins in the same county at different scales are compared and the Pearson correlation coefficients of users are computed. These results all demonstrate that social friendship correlates closely with human movements., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null,

articleAbstract=理解社交关系和移动行为的相关性，对于研究社交网络演化及建模人类移动是非常重要的。分析了两个基于位置社交网络网站用户的社交关系和签到行为，以量化社交关系与移动性的相关性。结果表明，社交或签到排名的概率分布反比于其排名，这意味着社交关系和移动性间存在着隐含的联系。通过对不同粒度下用户社交关系和签到行为的比较，以及用户皮尔逊相关系数的计算，证明社交关系和人类移动性存在较强的相关性。,
