dataset for multiple LBSs

Yelp is a typical one-platform dataset, with the last update at February 16 2021 for Yelp Dataset Challenge. Here, the review service is regarded as the check-in service because the review data record online interaction between users, whose fields include the useful count, the funny count and the cool count. We filter for users whose city is Austin, delete the records with missing values, and extract a subset of 45,524 users with 12,855 locations.
The foursSwarm dataset is obtained through the alternative crawl, whose user trajectories compose tips from Foursquare and check-ins from Swarm. In this dataset, locations are generated from October 9 2008 to November 5 2017, and are filtered by geographical distance within the fixed location number, i.e., 10,000 in this paper. After data was preprocessed, we eventually extracted a subset of 6,982 users with 12,503 locations.
