Abstract
A method for processing a first and second message groups submitted by a user includes executing a learning operation and an estimating operation. The learning operation includes extracting a first location message having a specifiable location from the first message group, extracting a first expression message including a specific expression from the first message group; and associating the location and the expression on the basis of the date and time submitted with each message, and for generating learning data. The estimating operation includes extracting a second expression message including a predetermined expression from the second message group, accepting input of a specified date and time for estimating a location; associating the expressions with each other on the basis of the specified date and time; and estimating a location at the specified date and time using coordination filtering on the basis of the learning data and the input data.
