To have RQ2 i manage prohibit retweets since the audience is trying to find the choices one profiles create once they article a great tweet that is geotagged (‘Dataset2′).

Amazingly, small employers and individual membership pros have the same number of geotagging while the semi-techniques work (cuatro.2%) even though the former classification have less ratio regarding pages that have location qualities allowed.
