“…Sentiment analysis has become a major area of interest in communication research. Recent applications include analyses of media tone (Van Atteveldt, Kleinnijenhuis et al, 2008a;Hopkins & King, 2010;Soroka & McAdams, 2015;Soroka, Young, & Balmas, 2015;Young & Soroka, 2012), agenda setting (Ceron, Curini, & Iacus, 2016), framing (Burscher, Odijk, Vliegenthart, De Rijke, & De Vreese, 2014), election forecasting (Ceron, Curini, & Iacus, 2015, and candidate evaluations (Aaldering & Vliegenthart, 2016). These studies do automated text analysis with sentiment dictionaries (Aaldering & Vliegenthart, 2016;Young & Soroka, 2012) or use machine learning (Van Atteveldt, Kleinnijenhuis et al, 2008a;Burscher et al, 2014;Ceron et al, 2016;Hopkins & King, 2010) to get sentiment scores.…”
