WIPO Patent Application WO/2017/064769
Kind Code:
A1
Abstract:
The purpose of the present invention is to calculate a distance between tables of records, each record consisting of a plurality of fields. In the information processing system according to the present invention, an axis determination unit 11 determines the order of fields of reference data G constituting a table. Following this order of fields, a data determination processing unit 12 first calculates the mutual information between the first field of the reference data G and the first field of target data T, and then calculates conditional mutual information between each subsequent field of the reference data G and the corresponding field of the target data T on the basis of fields preceding the subsequent field. The data determination processing unit then calculates a distance between the reference data G and the target data T on the basis of the mutual information, or the conditional mutual information, calculated for each field.
