Twitter trend prediction

Revisiting a research which aims to detect Twitter trends in advance...

Our most striking result is that we were able to detect Twitter trends in advance of Twitter’s trend detection algorithm a good percent of the time, while maintaining a low rate of error. In 79% percent of cases, we detected trending topics earlier than Twitter (1.43 hours earlier), and we managed to keep an error rate of around 95% (4% false positive rate, 95% true positive rate).
