From: Estimating community feedback effect on topic choice in social media with predictive modeling
Our predictive model can extract the topic trends which are related to news and social events. Topic trend extracted from three topic categories ((A) Sports, (B) Politics, and (C) Entertainment) are shown. The blue and green lines represent the mean topic trend of Reddit and Twitter, respectively, and the gray area represents the 95% confidence interval. Filled circles mark the days when the topic trend estimate is significantly higher than zero for at least three consecutive days. Social events manually identified from Wikipedia are written in magenta
