Climate Change Emotions on YouTube: The Case of Before the Flood
Xanat Vargas Meza,Matthew Shapiro,박한우 한국자료분석학회 2018 Journal of the Korean Data Analysis Society Vol.20 No.4
This study examines public comments on the trailer for Before the Flood, a climate change-oriented documentary released in October 2016. Through webometrics, semantic and sentiment analyses, emotions related to climate change were explored. Sentiment analysis of comments on videos examined in previous studies was compared with a sentiment analysis of post-video comments for Before the Flood. Relevant influencers on the comment network were identified, their discourse analyzed in depth, and the results showed an acute politicization of comments, partly due to the electoral campaign ongoing in the United States; while usage of scientific terms decreased. Influential users tended to express polarized views in favor or against the view that climate change is real. However, sentiment regarding climate change remained stable. This study contributes to the intersection of webometrics with environmental psychology as a useful tool to analyze media, particularly if it is targeted to a global audience.
South Korean Culture Goes Latin America: Social network analysis of Kpop Tweets in Mexico
Choi, Seong Cheol,Meza, Xanat Vargas,Park, Han Woo The Korea Contents Association 2014 International Journal of Contents Vol.10 No.1
Previous studies of the Korean wave have focused mainly on fan clubs by taking an ethnographic approach in the context of countries in Southeast Asia and, in a minor extension, Europe. This study fills the gap in the literature by providing a social network analysis of Tweets in the context of Mexico. We used the Twitter API in order to collect Twitter comments with the hashtag #kpop from March to August 2012, analyzing them with a set of webometric methodologies. The results indicate that #kpop power Twitterians in Mexico were more likely to be related to the public television broadcast. The sent Tweets were usually related to their programs and promotion for Kpop artists. These Tweets tended to be positive, and according to URLs, not only Kpop but also Korean dramas had considerable influence on the Korean wave in Mexico.
