Abstract: EEG to be measured on a scalp is estimated based on EEG measured from an ear canal. The program causes a processor included in an information processing apparatus to execute: acquiring first EEG information that is measured by a first bio-electrode that comes into contact with an ear canal of a predetermined user; acquiring second EEG information that is measured by a brain activity measuring instrument with respect to the predetermined user at the same timing as the first EEG information; learning a relationship between a first feature of the first EEG information and a second feature of the second EEG information; and generating a learning model that has learned the relationship.

Abstract: A viewing material evaluating method includes: a brain activity measuring step of measuring a brain activity of a test subject who views a viewing material by using a brain activity measuring unit; a first matrix generating step of generating a first matrix estimating a semantic content of perception of the test subject on the basis of a measurement result acquired in the brain activity measuring step by using a first matrix generating unit; a second matrix generating step of generating a second matrix by performing natural language processing for text information representing a planning intention of the viewing material by using a second matrix generating unit; and a similarity calculating step of calculating similarity between the first matrix and the second matrix by using a similarity calculating unit.
