Before revision:  We present two tools,birdspotter and evently, for analyzing online users based on their involvement in retweet cascades . birdspotter provides a toolkit to measure social influence and botnets of Twitter users. While it leverages the multimodal information of tweets, such as text contents, evently augments the user measurement by modeling the temporal dynamics of information diffusions using self-exciting processes.
After revision:  We present two tools,birdspotter and evently, for analyzing online users based on their involvement in retweet cascades . Here we present evently, a tool for modeling online reshare cascades, and particularly retweet cascades, using self-exciting processes. It provides a comprehensive set of functionalities for processing raw data from Twitter public APIs, modeling the temporal dynamics of information diffusions using self-exciting processes.
