13. A recording medium for storing a computer program which, when executed by a computer, causes said computer to operate as a translation server connected to a terminal via a network, said translation server performing the steps of: receiving a first translation instruction sent from the terminal, the first translation instruction including location information representing a location of an object document to be translated, source language information representing a source language of the object document and target language information representing a translation target language of the object document, and obtaining the object document to be translated from a Web server on the basis of the location information; separating the object document sent from the input information controller module into a translation object part and a non-translation object part; translating the translation object part sent from the information separator module according to the source language information and the target language information to obtain a translation result; producing a retranslation instruction part, the retranslation instruction part causing the terminal to display (1) at least one language information input column configured to receive source language information and/ or target language information input by the user for retranslation, (2) the location information, previously inputted by a user of the terminal, representing the location of the object document to be translated, and (3) a retranslation instruction input part, and, upon operation of the retranslation instruction input part by the user of the terminal, the retranslation instruction part causing the terminal to send to the translation server a second translation instruction including source language information and target language information from the language information input column and the location information of the object document to be translated, said location information being previously inputted by said user of the terminal in the first translation instruction; and assembling the translation result, the retranslation instruction part and the non-translation object part and sending a synthesized result to the terminal.

The recording medium as recited in claim 13 , which, when executed by said computer, causes said computer to further performs the steps of: converting link target document location information representing a location of a link target document included in the non-translation object part into a link target document translation instruction part for permitting the terminal to send the translation instruction including the source language information and the target language information in the language information input column and the link target document location information to a translation server system when the link target document is selected, and synthesizes the translation result sent from the translation server system, the retranslation instruction part and the converted non-translation object part after the conversion of the link target document location information into the link target document translation instruction part and sending a synthesized result to the terminal.
