Position-sensitive propagation of information on social media using social physics approach

摘要

The excitement and convergence of tweets on specific topics are well studied. We can also investigate the position-sensitive subjects by utilizing the position information of tweets. In this research, we focus on bomb terrorist attacks and propose a method for separately analyzing the number of tweets at the place where the incident occurred, nearby, and far. We made measurements of position-sensitive tweets and suggested a theory to explain it. This theory is the theory of social physics that can analyze epidemic phenomena such as movies and hit products from the time change of the number of social media writing. This paper expanded this theory to take into account the position where Tweet was transmitted. With this theory we found that it is possible to explain the spread of information by the tweets with location information on the bomb case.
