INFORMATION PROCESSING SYSTEM, POPULATION FLOW RATE ESTIMATION APPARATUS, COMPUTER-READABLE MEDIUM, INFORMATION PROCESSING METHOD AND METHOD OF ESTIMATING POPULATION FLOW RATE

摘要

In conventional techniques, obtained information is not utilized sufficiently. A system comprises: a movement history acquiring unit that acquires one or more pieces of movement history information in which terminal identification information identifying each of one or more communication terminals, terminal positional information indicating a position at which a communication terminal is present, and acquisition clock time information indicating a clock time at which the terminal positional information has been acquired are associated; and a presence probability generating unit that generates, based on the one or more pieces of movement history information, each of one or more pieces of presence probability information about a probability that a communication terminal present in a first area from among one or more areas having predetermined geographical ranges is present in a second area from among the one or more areas after each of one or more predetermined periods of time has elapsed.
