This paper examines how emotional reactions to political events shape public opinion. We analyze political discussions in which people voluntarily engage online to approximate the public agenda: Online discussions offer a natural approach to the salience of political issues and the means to analyze emotional reactions as political events take place in real time. We measure shifts in emotions of the public over a period that includes Taiwan’s presidential election before, during and after during Chou Tsz-yu incident broke out. The uproar over Ms. Chou’s apology was so intense during the president election. Our findings show that emotional reactions to political events help explain rising anger rates for the same period, which casts novel light on the mechanisms that mediate the association between agenda setting and political evaluations. The political cultural context of the country and how it determines emotion sharing in online debate were analyzed. Big data content analysis of Taiwan’s political discussions on Facebook revealed that this sort of oppression from China really upsets people in Taiwan. Provoking the feelings of the public’s political views and anxiety were two significant factors underpinning the high level of political discussion. Additional analyses suggest how the news sources and social media perceived most important issues can have positive correlations between use of Internet sites and interest in political event.
