PROGRAM, DEVICE AND METHOD FOR ESTIMATING ABILITY OF EMPATHY OF USER WITH RESPECT TO CONTENT

摘要

To provide a program and the like for estimating ability of empathy of a user with respect to content.SOLUTION: As a learning function, for each user (sto s), a machine learning engine learns as teacher data that ability of empathy θbased on IRT (Item Response Theory) in an empathy degree matrix Tassociated with empathy degrees (tto tthrough tto t) of each content c(cto c) and a user feature amount matrix Fassociated with feature amounts (fto fthrough fto f) of each predetermined user feature element (vto v) are associated with each other. As an operation function, regarding an estimation target user s, a user feature amount matrix Fassociated with feature amounts (fto f) of each predetermined user feature element (vto v) is calculated and the machine learning engine accepts input of the user feature amount matrix Fof the estimation target user sand outputs ability of empathy θ.SELECTED DRAWING: Figure 2
