Personality Estimation from SNS Messages and its Application to Evaluating a City Personality

The study proposes a method which enables the estimation of the personality of a single person from text-based their messages. The method can also reveal the personality of people staying in a city when applying the method to all public messages exchanged over a social networking service (a.k.a. SNS) originating from the city. This might be called “city personality”. In experiments, the method was applied to four cities in the U.S.A. and two cities in the U.K. The results make the differences in the personality between cities clear.
