PROBLEM TO BE SOLVED: To provide a translation model generation device, a method and a program which can improve translation accuracy regardless of languages.SOLUTION: A translation model generation server 1 comprises: a character string extraction unit 12 which extracts a plurality of partial character strings with a mutually inclusive relation from sentences of a first language and sentences of a second language which are included in a plurality of combinations of the sentences of the first language and the sentences of the second language; a graph generation unit 13 which generates a digraph so that a node includes the partial character string corresponding to the sentences of each language extracted by the character string extraction unit 12 and a partial character string included in a parent node includes a partial character string included in a child node, for both the sentence of the first language and the sentence of the second language included in each of the plurality of combinations; and an alignment unit 14 which totals corresponding states between the partial character strings of the first language and the partial character strings of the second language extracted by the character string extraction unit 12 and performs alignment between nodes included in the generated digraph on the basis of the totaling result. |
