The Dynamics of Retweeting on Twitter
Add to Google Calendar
In this work we analyze the dynamics retweeting in the micro-blogging site Twitter. We propose a model for Twitter users' retweeting behavior which incorporates two key elements: the arrival patterns of users to Twitter and the design of the Twitter user interface. Using only these elements, our model predicts a distribution of user retweet times which agrees with observations on over 2.4 million retweets in Twitter. Our model allows us to predict the probability of a tweet being viewed by a specific user and the impact of promotional activity on the visibility of a tweet. This suggests that our model can serve as a tool to optimize advertising services provided by Twitter which promote tweets.
