A SYSTEM FOR DIVIDING A CHARACTER STRING IN A MACHINE TRANSLATION PROCESS

A dividing device includes: an acquisition unit that acquires a plurality of words constituting a character string one by one from a head of the character string; a first calculation unit that calculates a forward division likelihood indicating a likelihood of dividing the character string at a position in front of a first word acquired by the acquisition unit and a backward division likelihood indicating a likelihood of dividing the character string at a position immediately after the first word; a detection unit that detects a division point based on the forward division likelihood and the backward division likelihood, the division point being a position at which the character string is divided; a generation unit that generates a chunk by dividing the character string at the division point; and an output unit that outputs the chunk.
