  • a storage device for storing a plurality of body word sets, each of which is constituted with a word string having a plurality of words, and a plurality of duplicate word sets, each of the plurality of duplicate word sets being composed of a part of a word string of a respective body word set, and has a name identical to that of the respective body word set, wherein the plurality of body word sets and the plurality of duplicate word sets constitute ambiguous retrieval data;

    a specifying device for specifying a retrieving character string;

    a retrieving device for retrieving the body and the duplicate word sets which include a character string that coincides with the retrieving character string from the ambiguous retrieval data;

    a display device for displaying a name; and

    a selecting device for selecting one word set among one body word set and each of the plurality of duplicate word sets that has the name identical to that of the one body word set while automatically suppressing the display of the name of the one body word set together with the display of the name of the duplicate word set having the name identical to that of the one body word set, when the one body word set and at least one of the plurality of duplicate word sets are retrieved by the retrieving device, and for sending the selected one word set to the display device so that the name thereof is displayed as the name to be displayed at the display device, wherein the name of the one word set selected by the selecting device is displayed at the display device while display of a plurality of names identical to the name of the one word set are prohibited by the selecting device without selection by a user; and

    the storage device stores a body word set and one or more duplicate word sets corresponding to an identical name in a predetermined order, a number of overlapping characters of each of the body word and duplicate word sets is also stored in association with each of the body and duplicate word sets, the number of overlapping characters representing a number of characters of an arbitrary one of the body and duplicate word sets that match characters composing another of the body and duplicate word sets stored before the arbitrary one, from a head character thereof, and wherein the selecting device selects a word set whose number of overlapping characters is smaller than the number of characters in the retrieving character string specified through the specifying device when the body word and the duplicate word sets corresponding to the identical name are retrieved by the retrieving device.
