Outline of Final Research Achievements |
Information cascade through friendship networks is one of the most important phenomena on social media. We analyzed information cascades on heterogeneous topics, and investigated how their cascading behaviors affected by features, such as contents, paths of cascades, involved users, and languages. Based on the analysis, we proposed methods for classifying cascades by their social influence, and for predicting occurrence of cross-lingual cascades. Finally, we developed a system for visualizing cascading behaviors.
