PROBLEM TO BE SOLVED: To present retrieval target data in proper order by use of an inputted retrieval key and inputted additional information. SOLUTION: Data that are a retrieval target and a plurality of characteristic amounts and related information of the data are previously stored in a data accumulation part 15. Data that are the retrieval key are inputted by a key input part 12, and a characteristic amount of the retrieval key inputted to the key input part 12 is calculated by a characteristic amount calculation part 13. A distance between the characteristic amount of the retrieval key calculated in the characteristic amount calculation part 13 and each of the characteristic amounts stored in the data accumulation part 15 is calculated by a distance calculation part 16. Information that is a hint when performing retrieval in an additional information input part 14 is inputted. In a rearrangement part 17, the distances of the plurality of characteristic amounts calculated in the distance calculation part 16 are integrated by an integration vector calculated based on the additional information inputted in the additional information input part 14, and the order of presenting the retrieval target data is rearranged.
