PROBLEM TO BE SOLVED: To quickly register data in a data group as an object of retrieval of similar data without complicating a retrieval index. SOLUTION: When a plurality of pieces of registration data are input, similar data about each registration data are quickly retrieved by graph retrieval processing of a graph retrieval part 40. Also, a similar data acquisition part 51 in a data registration part 50 inputs registration data to a graph retrieval part 40, and obtains a retrieval result (similar data) about each registration data. Then, a merge part 53 generates a link between the registration data and the similar data. Also, the merge part 53 generates a link between the pieces of registration data, and reads link information of the similar data from a graph index DB70, and merges it on a temporary memory 80. A link optimization part 55 reduces the number of links on the basis of the number of links and the length of the link. Then, database registration is performed by optimizing the number of links generated by additional registration. COPYRIGHT: (C)2011,JPO&INPIT
