Most previous research on user geolocation has focused either on text-based classification approaches (Eisenstein et al., 2010; Wing and Baldridge, 2011;<cite> Roller et al., 2012</cite>; Han et al., 2014) or, to a lesser extent, network-based regression approaches (Jurgens, 2013; Compton et al., 2014;<cite> Rahimi et al., 2015)</cite> . Methods which combine the two, however, are rare.
