social media text carries implicit information about the author, which has been modeled in natural language processing (NLP) to predict author characteristics such as age (Goswami et al., 2009;Rosenthal and McKeown, 2011;Nguyen et al., 2014), gender (sarawgi et al., 2011;Ciot et al., 2013;Liu and Ruths, 2013;Volkova et al., 2015;Hovy, 2015), personality (schwartz et al., 2013;Volkova et al., 2014;Plank and Hovy, 2015;Preoţiuc-Pietro et al., 2015), and occupation (Preotiuc-Pietro et al., 2015).
