apparatus and method for hierarchical analysis of data based on mutual correlations, and computer program product

摘要

The present invention relates to access to data selected by a user based on correlation analysis. It is proposed in the present invention to introduce attribute value normalization and a hierarchical analysis of data based on mutual correlations between attributes. Normalization of attribute scale values at nominal values provides a basis for the hypothesis of correlations between attributes, thus scientifically justifying further observation and comparison. Multilayer hierarchical investigation enables not only attribute-level analysis but also related data, which provides a more detailed look.
