Abstract (in Japanese) (See Japanese page) 
(in English) Acquiring information about trend topics from social media can be useful for broadcasters to make TV program. In order to find trend Tweets and topics efficiently, broadcasters refer to the number of reactions such as “Retweet”. However, Tweets that have a large number of reactions are frequently posted about popular games and campaigns of enterprises. These Tweets are unnecessary to make programs. In this paper, we present a trend extraction method that focus on emotional polarity of Tweet as well as the number of reactions. Because emotional reactions on SNS reflect the occurring of real-world events and should be important for event detection. As a result of evaluation based on information shared in the broadcasting station, we confirm our method that focus on changes in the proportion of emotional polarity can extract Tweet that useful for broadcasters.
