Twitter地理标签行为的大规模实证研究

A Large-Scale Empirical Study of Geotagging Behavior on Twitter

Binxuan Huang, Kathleen M. Carley

摘要:

社交媒体上的地理标记已成为了解人们流动性和社交活动的重要代理。使用地理标记来推断公众意见的研究依赖于对地理标记和非地理标记用户行为的几个关键假设。然而,这些假设尚未得到充分验证。缺乏对地理标记行为的了解阻碍了人们进一步利用它。本文基于从2000万用户收集的400多亿条推文,对Twitter上的地理标记行为进行了实证研究。有三个主要的发现可能会挑战这些共同的假设。首先,不同的用户群体具有不同的地理标记偏好。例如,只有不到3%的韩语用户使用地理标记,而超过40%的印度尼西亚语用户使用地理标记。其次,在配置文件中报告其位置的用户更有可能使用地理标记,这可能影响那些位置预测系统对非地理标记用户的可生成性。第三,用户的地理标记行为存在较强的同质性效应,即用户倾向于连接到具有相似地理标记偏好的朋友。

英文摘要:

Geotagging on social media has become an important proxy for understanding people's mobility and social events. Research that uses geotags to infer public opinions relies on several key assumptions about the behavior of geotagged and non-geotagged users. However, these assumptions have not been fully validated. Lack of understanding the geotagging behavior prohibits people further utilizing it. In this paper, we present an empirical study of geotagging behavior on Twitter based on more than 40 billion tweets collected from 20 million users. There are three main findings that may challenge these common assumptions. Firstly, different groups of users have different geotagging preferences. For example, less than 3% of users speaking in Korean are geotagged, while more than 40% of users speaking in Indonesian use geotags. Secondly, users who report their locations in profiles are more likely to use geotags, which may affects the generability of those location prediction systems on non-geotagged users. Thirdly, strong homophily effect exists in users' geotagging behavior, that users tend to connect to friends with similar geotagging preferences.
