从Twitter了解人类流动

Understanding Human Mobility from Twitter

Raja Jurdak, Kun Zhao, Jiajun Liu, Maurice AbouJaoude, Mark Cameron, David Newth

摘要:

了解人类流动对于从疾病预测到通信网络的广泛应用至关重要。到目前为止,研究人类流动的大多数努力都使用私有和低分辨率数据,例如呼叫数据记录。在这里,我们建议Twitter作为人类流动的代理,因为它依赖于公开的数据,并提供高分辨率定位时,用户选择地理标记他们的推文与他们的当前位置。我们分析了一个Twitter数据集,其中包含在澳大利亚发布的600多万条带有地理标记的推文,我们证明Twitter可以成为研究人类流动模式的可靠来源。我们的分析表明,地理标记的推文可以捕捉到人类流动的丰富特征,如个人之间的运动轨迹的多样性和城市内部和之间的运动。我们还发现,短距离和长距离的移动都花费他们的大部分时间在大都市地区,在对比中距离的移动,反映了不同的旅行方式的影响。我们的研究提供了坚实的证据,证明Twitter确实可以成为跟踪和预测人类运动的有用代理。

英文摘要:

Understanding human mobility is crucial for a broad range of applications from disease prediction to communication networks. Most efforts on studying human mobility have so far used private and low resolution data, such as call data records. Here, we propose Twitter as a proxy for human mobility, as it relies on publicly available data and provides high resolution positioning when users opt to geotag their tweets with their current location. We analyse a Twitter dataset with more than six million geotagged tweets posted in Australia, and we demonstrate that Twitter can be a reliable source for studying human mobility patterns. Our analysis shows that geotagged tweets can capture rich features of human mobility, such as the diversity of movement orbits among individuals and of movements within and between cities. We also find that short and long-distance movers both spend most of their time in large metropolitan areas, in contrast with intermediate-distance movers movements, reflecting the impact of different modes of travel. Our study provides solid evidence that Twitter can indeed be a useful proxy for tracking and predicting human movement.
