A user terminal acquires data indicating a behavioral status of a user, acquires area stay information including position information of the area in which the user is staying and stay time information which is the amount of time for which the user has stayed in the area, stores the data which the user terminal has acquired, reads the stored data according to the acquired area stay information, and on the basis of the read data, assesses the behavioral status of the user, and generates a behavioral status time-sequence pattern indicating the behavioral status of the user. On the basis of the generated behavioral status time-sequence pattern, the user terminal calculates behavioral feature values indicating features of the behavior of the user. Using the calculated behavioral feature values, an area interest level indicating the degree and tendencies of interest of a user for the area is assessed.
