PROBLEM TO BE SOLVED: To increase the accuracy of candidate extraction in associating data items between different data schemas. SOLUTION: Data item names constituting a source data schema are extracted (1051), and data item names constituting a target data schema are extracted (1052). Element concepts included in the extracted data item names of the source data schema and target data schema are extracted (1053). Distinctive relationships between the data item names are set from the extracted element concepts and stored in an ontology 1061. The data item names of the source data schema and the data item names of the target data schema are read in, and a correspondence between every two data item names read is set according to the distinctive relationships and stored in a mapping definition file 1071.
