User attribute estimating program for estimating the user attributes by using the life-related amount of the decision tree, the apparatus and method

摘要

PROBLEM TO BE SOLVED: To provide a user attribute estimation program capable of estimating user attributes on the basis of a life related quantity without depending on an input by a user and a questionnaire survey.;SOLUTION: The user attribute estimation program causes a computer to be functioned as: subset generation means that generates subsets from teacher data set containing a set of unit-period data (life related data in a unit period) and a user attribute value; decision tree generation means that generates a decision tree formed by associating a leaf node as a result of learning by a branch decision expression, with the user attribute value for each generated subset; unit attribute estimation means that inputs the unit-period data constituting estimation object data in a prescribed estimation period in a plurality of generated decision trees, and determining a unit user attribute value on the basis of the user attribute value associated with the leaf node of the decision tree as a destination; and user attribute estimation means for determining a user attribute estimation value in the estimation period on the basis of the unit user attribute estimation values.;COPYRIGHT: (C)2014,JPO&INPIT
