Brightkite

Brightkite:  Dataset with multiple aspect trajectories from users of the Brightkite social media, collected between April 2008 and October 2010. The original dataset has a total of 4,491,143 check-in points from 58,228 users, and it provides the anonymized user that made the check-in, the POI semantic reference and the spatio-temporal information of where and when the check-in was made. The trajectories were split in weeks in order to have many trajectories examples for each user as necessary for classification tasks. We used a total of 300 random users for analysis, with a filter of a minimum of 10 points and maximum of 50 points per trajectory to guarantee consistency. Trajectories were enriched with the semantic information of the weekday of each check-in, and the resultant dataset has a total of 7,911 trajectories, with trajectory sizes varying from 10 to 50 points.
