METHOD FOR DIAGNOSING KNOWLEDGE BY USING ONTOLOGY-BASED KNOWLEDGE MAP

摘要

The present invention relates to a method for diagnosing the knowledge of a person whose knowledge is to be diagnosed from verification data of the person by using an ontology-based knowledge map composed of relationships of knowledge objects, and proposes a method for performing diagnosis in a manner of correcting the knowledge level of a person whose knowledge is to be diagnosed by comparing and evaluating knowledge related to specific knowledge, rather than determining the knowledge level of the person with respect to the specific knowledge by using only an evaluation on the specific knowledge. To this end, the present invention determines the knowledge level by periodically repeating a forward propagation knowledge diagnosis process and a backward propagation knowledge diagnosis process which use the gradient descent of neural network theory so as to cause knowledge errors between the evaluated knowledge level and the corrected knowledge level of the person whose knowledge is to be diagnosed to converge.
