PROBLEM TO BE SOLVED: To provide a general-purpose data fusion system which can perform the same additional research data fusion as when additional research is performed with all subjects of basic data by performing additional research with a part of the subjects in the basic data.SOLUTION: A computer device C has additional research subject extraction means 6, additional research database creation means 7, and similarity calculation means 8. An operation part of the computer device C has answer content data of an additional research database calculated by the similarity calculation means 8 as virtual additional data, identifies the same data as additional research data, imparts it as additional research data to each of subject data which is not included in subjects extracted by the additional research subject extraction means 6 and about whom additional research has not be performed, imparts the identified additional research data to all subjects extracted by the additional research subject extraction means of a basic database and subjects who are not extracted by the additional research subject extraction means, and fuses the additional research data with the basic database. |
