DATA PROCESSING DEVICE, CONDITIONAL FUNCTIONAL DEPENDENCY RULE INTEGRATION METHOD, AND PROGRAM

摘要

This data processing device is provided with: data input means for inputting a data table to be processed and a conditional functional dependency rule list; identification means for identifying pairs of conditional functional dependency rules having the same attribute collection in a condition portion, a premise portion, and a consequence portion from the conditional functional dependency rule list; calculation means for calculating possibilities of integration using a condition portion compliance number and/or a premise portion match number and/or a dependency match number and/or a dependency mismatch number for the identified pairs of conditional functional dependency rules; and information presentation means which extracts data tuples related to the integrated conditional functional dependency rules on the basis of the possibilities of integration in order to output information related to the extracted data tuples.
