<p><P>PROBLEM TO BE SOLVED: To provide a character string conversion device which has improved accuracy of converting character strings, a retrieval device, a character string conversion method, and a character string conversion program. <P>SOLUTION: The character string conversion device includes: a conversion candidate generation part which generates one or more conversion candidates including character strings other than an input character string; a conversion probability calculation part which divides each of one or more conversion candidates into one or more character strings, and calculates a conversion probability with which the input character string may be converted to each of the one or more conversion candidates, on the basis of statistical information on appearance of the one or more character strings; and a conversion candidate extraction part which extracts at least one conversion candidate from the one or more conversion candidates on the basis of the conversion probability. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
