USAGE ESTIMATION DEVICE
First Claim
1. A usage estimation device that, when a trajectory made by dividing operation history information of a user on a terminal device by time, calculating a group of feature amount representing usage for each piece of the operation history information in each division section, and connecting points corresponding to the group of feature amount on a space based on the feature amount is referred to as a usage trajectory,compares the usage trajectory of each reference user calculated from the operation history information of a plurality of reference users with the usage trajectory calculated from the operation history information of a user to be analyzed, andestimates future usage of the user to be analyzed from the usage trajectory of the reference user that is similar to the usage trajectory of the user to be analyzed.

Abstract
Predicting a transition of usage of a user on a terminal device. A trajectory made by dividing operation history information of a user on the terminal device by time, calculating a group of feature amount representing the usage for each piece of the operation history information in each division section, and connecting points corresponding to the group of feature amount on a space based on the feature amount is referred to as a usage trajectory. A processing device 110 compares the usage trajectory of each reference user calculated from the operation history information of a plurality of reference users with the usage trajectory calculated from the operation history information of a user to be analyzed, and estimates future usage of the user to be analyzed from the usage trajectory of the reference user that is similar to the usage trajectory of the user to be analyzed.
