Due to twitter's terms of use, the source data only contains tweet identifiers. A tool such as twarc can be used to hydrate these identifiers in order to get the contents, extract the swarm check-in URL from the contents, and get the foursquare venue identifier. The scripts to do this are in the scripts directory.
