On the validity of geosocial mobility traces
2013
Proceedings of the Twelfth ACM Workshop on Hot Topics in Networks - HotNets-XII
Preserved Fulltext
Recently, researchers have begun to focus on geosocial mobility traces, e.g. Foursquare checkin traces, because of their availability and scale. But are we conceding correctness in our zeal for data? ...
In this paper, we take initial steps towards quantifying the value of geosocial datasets using a large ground truth dataset gathered from a user study. ...
To the best of our knowledge, our study is the first to quantitatively evaluate the accuracy and validity of geosocial mobility traces. ...

These findings indicate activity centres defined from Twitter do relate to general spatial activities, but the limited degree of spatial variability on an individual level limits the applications of geosocial ...
Additionally, we find that the broader pattern of geosocial footprints indicated that 35 percent of users have only one activity centre, 30 percent have two activity centres, and 14 percent have three ...
