我的追随者呢?理解Twitter中的局部性效应

Where are my followers? Understanding the Locality Effect in Twitter

Roberto Gonzalez, Ruben Cuevas, Angel Cuevas, Carmen Guerrero

摘要:

Twitter是目前互联网上使用最多的应用程序之一,迄今已创建了超过2亿个帐户。与其他大规模系统一样,Twitter也可以利用用户之间存在的局部性效应来获得优势。在本文中,我们进行了第一次全面的研究,Twitter的本地化效应。为此,我们收集了大约100万Twitter用户及其1600万追随者的地理位置。我们的研究结果表明,语言和文化特征决定了不同国家的本地化水平。那些语言不同于英语的国家,如巴西,通常表现出很高的国内局部性,而那些英语是官方语言或共同官方语言的国家则受到外部局部性效应的影响。也就是说,他们的用户在美国的粉丝数量比在同一个国家的粉丝数量要多。这是由两个原因造成的:第一,美国是Twitter的主导国家,大约有一半的用户,第二,这些国家与美国有共同的语言和文化特征。

英文摘要:

Twitter is one of the most used applications in the current Internet with more than 200M accounts created so far. As other large-scale systems Twitter can obtain enefit by exploiting the Locality effect existing among its users. In this paper we perform the first comprehensive study of the Locality effect of Twitter. For this purpose we have collected the geographical location of around 1M Twitter users and 16M of their followers. Our results demonstrate that language and cultural characteristics determine the level of Locality expected for different countries. Those countries with a different language than English such as Brazil typically show a high intra-country Locality whereas those others where English is official or co-official language suffer from an external Locality effect. This is, their users have a larger number of followers in US than within their same country. This is produced by two reasons: first, US is the dominant country in Twitter counting with around half of the users, and second, these countries share a common language and cultural characteristics with US.
