Defense cost sharing, Twitter, Word Cloud, Social Network, Latent Dirichlet Allocation


To study, Twitter, the social media, was selected and analyzed by applying word cloud, social network and LDA techniques as keywords. The results showed that the main key words based on frequency were "THADD", "resident in Korea," "rise," "burdened," and "negotiation," while the main key words considering word relationship and centrality were "THADD," "opposite," "cost," "deployment" and "aligned alliance." In addition, LDA technology has shown that 'THADD base construction costs', 'the withdrawal of U.S. troops from South Korea', 'Recommendation of unpaid leave of Korean workers' and 'the government's efforts to reopen negotiations' have become an issue in the current negotiation process related to 'defense cost sharing'.
Through this, it was possible to identify the key words that the public recognizes “defense-sharing expenses,” and furthermore, the government should pursue strategic negotiation policies in consideration of the key words and topics recognized by the people in order to achieve successful negotiation results.
