PROBLEM TO BE SOLVED: To selectively present an important dimension by defining an importance level of a dimension, in general multidimensional data analysis.;SOLUTION: A dimension importance level calculation part 102 extracts a plurality of combinations between pieces of m-dimensional (m is an integer ≥1 and n) data from n-dimensional data stored in a dimensional data recording part 101, and analyzes a characteristic of a distribution of the data in an m-dimensional space in each extracted combination by a processor. A dimension selection part 104 selects one combination based on the importance level of each combination calculated by the dimension importance level calculation part 102. A data presentation part 105 outputs the m-dimensional data constituting the combination selected by the dimension selection part 104 from an output device.;COPYRIGHT: (C)2011,JPO&INPIT
