TECHNICAL DOCUMENT ATTRIBUTE ASSOCIATION ANALYSIS SUPPORTING APPARATUS

摘要

Data on a group of technical documents having an attribute X and an attribute Y is acquired and a score corresponding to the data on the technical documents belonging to the combination of the attribute X and attribute Y is calculated. The attribute X is placed on the horizontal axis and the attribute Y is placed on the vertical axis. The scores are placed in a matrix. According to the scores belonging to each column of the placement in the matrix, a group of vectors Xj are created. According to the scores belonging to each line, a group of vector Yk are created. For the vectors Xj, Yk, vectors having higher association with each other are placed nearer to each other. The associations between the vectors of the first group corresponding to the first attribute X of the technical document and the associations between the vectors of the second group corresponding to the second attribute Y are analyzed in detail, and examination in consideration of both first and second attributes X, Y can be performed.
