this present study is the first attempt to validate the efficacy of the LDA model in the context of journalism and mass communication research. Considering its decent performance, future research should consider using this method to analyze mass communication text, especially to process large-scaled social media data. For example, when communication scholars have a big dataset, but are unsure of the topics or attributes that exist inside of it, our results suggest the LDA-based analysis will be more effective than using the most frequently used words to devise topic lists.
