1. A computer-readable storage medium which stores a hypertext conversion program characterized by causing a computer to execute a processing starting part determination step in which a processing starting part is determined in an original hypertext serving as a processing object; a processing range determination step in which a processing range including an original anchor in the original hypertext is determined based on the processing starting part; a link destination hypertext acquisition step in which a link destination hypertext of the original anchor present in the processing range is acquired; a link destination anchor information extraction step in which link destination anchor information composed of a pair of a character string and a link destination URL of a link destination anchor is extracted from the link destination hypertext; an original anchor effective range determination step in which an original anchor effective range is determined which serves as a candidate character string range to which a new anchor is added in the original hypertext; a character string comparison step in which a character string present in the original anchor effective range is compared with the character string present in the link destination anchor information, and in which a matched range in the original anchor effective range is determined; a new anchor information generation step in which the link destination URL paired with the link destination character string of the link destination anchor information which is matched in the character string comparison is set as a new link destination URL, and in which new anchor information is generated composed of a pair of the matched range and the new link destination URL; and a new anchor attachment step in which a new anchor describing the new link destination URL in the new anchor information is attached to a character string of the original hypertext present in the matched range in the new anchor information, so as to convert the original hypertext to a new hypertext.

The storage medium according to claim 1 , characterized in that, in the new anchor information generation step, when a plurality of new link destination URLs correspond to the same matched range of the new anchor information, priorities are given to the new link destination URLs; and, in the new anchor attachment step, a plurality of new anchors corresponding to the plurality of new link destination URLs are attached to the matched range in the original hypertext based on the priorities.
