When a keyword described in Japanese is input, the input keyword is converted from Japanese into English. Thus, a retrieval keyword described in English is generated based on the input keyword described in Japanese. Documents that are described in English and that contain the retrieval keyword described in English are retrieved from a database. The retrieved documents are translated from English into Japanese. The documents translated into Japanese are compared with the input keyword described in Japanese. Thus, the validity of the results retrieved from the database is evaluated. Thus, even if the language of a database from which the data is retrieved is different from the language of the input keyword, retrieved results exactly based on the input keyword can be output. |
