DATA PROCESSOR, DATA PROCESSING METHOD, DATA PROCESSING PROGRAM AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a data processor capable of executing proper classification and display of classification results thereof even when a similarity degree is decided with respect to a specific attribute of a target.

SOLUTION: This data processor 1 has: a storage part 10 storing the similarity degree between the target and each of other targets included in a plurality of targets with respect to the specific attribute of the target about each of the plurality of targets; a sequence interchanging part 20 arranging the similarity degree between the target and each of the other targets to configure a row, arranging the row configured about each of the plurality of targets to configure a matrix, and interchanging the rows and columns of the matrix such that an element having a large similarity degree among elements of the matrix approaches a diagonal D of the matrix on the basis of a prescribed estimation function related to the similarity degree; and a display part 30 graphically displaying information about whether the plurality of targets respectively have similar relation to each other on the basis of the matrix wherein the rows and the columns are interchanged by the sequence interchanging part 20.
