| Abstract(in English) | To categorize Web information as educational material, the relationships between subjects and terms that appeared in the teaching guidelines were analyzed by using the Singular Value Decomposition method, and feature vectors were extracted.The percentage corrects for classification of teaching schemes were higher in science and several subjects by using the dot-production of feature vectors.The Web information as educational or general material were also classified to a subject and grade in the same way.The degree of containing rate for dictionary terms and similarity to the subjects were compared among web documents.Codebook vectors, that were learned by a Self-Organizing Algorithm with feature vectors, then put the terms and subjects into a 2-dimensional map that described their relationship.It was examined that a Self-Organizing Map could be used for classification of Web information to the subject and grade. |
