CHARACTER STRING CONVERSION DEVICE, RETRIEVAL DEVICE, CHARACTER STRING CONVERSION METHOD, AND CHARACTER STRING CONVERSION PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a character string conversion device for efficiently converting character strings.SOLUTION: The character string conversion device includes: a conversion candidate generation part which generates one or more conversion candidates including character strings different from an input character string; a selection key allocation part which allocates one or more selection keys to each of the one or more conversion candidates, respectively; and an output part which outputs a conversion candidate with the selected selection key allocated thereto as a defined character string when a key is operated to select any of the one or more selection keys in succession to a key operation for inputting the character string.
