<P>PROBLEM TO BE SOLVED: To achieve an unlimited length of unknown word morpheme candidates, exclusion of extremely improper unknown word morpheme candidates, and avoidance of reduction in generation probability of the unknown word morpheme candidates. <P>SOLUTION: The device comprises: a morpheme division point probability calculation means which calculates a morpheme division point probability in which a space between words in an input sentence is a division point of morpheme; a morpheme probability calculation means which calculates a morpheme probability in which a character string in the input sentence is a morpheme; and a morpheme candidate determination means which determines all character strings which will be morpheme candidates in the input sentence. <P>COPYRIGHT: (C)2009,JPO&INPIT |
