Material evaluation method and material evaluation device

Abstract

The present invention provides a material evaluation method, including: a brain activity detection step, the brain activity detection part presents the training material to the subject and detects brain activity; a meaning space construction step, the meaning space construction part is based on the detection detected by the brain activity detection step The result and the language description obtained by performing natural language processing on the content of the training material are used to construct the meaning space in the brain representing the relationship between brain activity and the meaning in the brain of the words appearing in the language description; in the first estimation step, the material estimation part is based on the new The content of the material is subjected to language description obtained by natural language processing, and the first position corresponding to the content of the new material in the meaning space in the brain is estimated; in the second estimation step, the target estimation part estimates the target word in the brain according to the target word representing the target concept of the new material. a second position corresponding to the target word in the inner meaning space; and an evaluation step in which the evaluation processing unit evaluates the new material based on the first position estimated by the first estimation step and the second position estimated by the second estimation step.

Description

technical field [0001] The present invention relates to a material evaluation method and a material evaluation device. [0002] This application claims priority based on Japanese Patent Application No. 2016-7314 filed in Japan on January 18, 2016, the content of which is incorporated herein. Background technique [0003] In recent years, there has been known a technique for estimating the content of the sense meaning perceived by the subject by detecting the subject's brain activity (for example, Patent Document 1). In the technique described in this Patent Document 1, materials such as video, audio content, and various products are evaluated in the following steps. In the prior art described in Patent Document 1, firstly, the subject is shown stimulation scenes including animations and the like, and brain activities induced by these stimuli are detected. Then, in the prior art, for the stimulus-brain activity group data, a corresponding brain meaning space as an intermedi...

Problems solved by technology

[0007] However, in the prior art, whenever a new material (new material) is required to be evaluated, it is necessary to show the new material to the subject to detect the brain activity, and it is difficult to perform evaluation quickly and easily.
