Outline of Final Research Achievements

We analyzed large scale social data and confirmed empirical laws of trending words. Then we constructed agent-based model which reproduces the empirical laws. Namely we clarified the relationships between microscopic agents’ behaviors and macroscopic dynamics of trending words. By analyzing the agent-based model theoretically, we introduced “life cycle equation of trending words” which characterizes the time evolution of trending words' frequency. Also we constructed early detection and control methods of false rumors.
