PROBLEM TO BE SOLVED: To provide an integrated retrieval device allowing a user to cheaply and easily use it without considering structures of individual retrieval devices, and capable of properly retrieving data demanded by the user. SOLUTION: When a keyword is inputted by an input means 2a, a keyword expansion means 2c expands the inputted keyword to a keyword group related thereto by using a keyword expansion function of a retrieval device having the keyword expansion function; and a data registration control means 2d registers the keyword based on the expanded keyword group to a retrieval device of a registration object by relating it with data. Thereby, even when data are retrieved by the retrieval device without having a keyword expansion function, the data can be properly retrieved like the retrieval device having the keyword expansion function.
