Topics and their salience in the 2015 parliamentary election in Croatia:uda topic model based analysis of the media agenda

摘要

There is a growing interest in automated content analysis for agenda-setting studies. While topic models have shown to be useful for this purpose, they are generally troubled with low topic quality and coverage. To alleviate this, Korenčić et al. (2015) proposed a semi-supervised topic modeling methodology. The aim of this work is to gain a better understanding of their methodology, by conducting a preliminary study of the media agenda during the 2015 parliamentary election in Croatia. Our goal is to analyze the topics and their salience during the official election campaign and the lively post-election negotiation period. We report on the methodological insights gained from this study and a preliminary analysis of the media agenda during the election period.
