Abstract

A device includes a parsing unit that parses an input sentence into a plurality of clauses, an identification unit that identifies, as a target area, based on the clauses resulting from the parsing, any of the clauses corresponding to an area specified, a setting unit that sets, as a target clause, any of the clauses located at a boundary of the target area identified, and sets, as a candidate for modification of the target clause, any of the clauses adjacent to the target clause in the target area. A judgment unit judges whether there exists a relationship of modification between the target clause and the candidate for modification and a determination unit determines, when the judgment unit judges that there is the relationship of modification, a translation area based on the target area, the target clause, and the candidate for modification.

the determination unit determines, when the judgment unit judges that the target area includes the modifiee, a range from the clause which is the modifiee to the clause located at the tail end as the size-increased translation area.

11. The translation assistance device according to claim 9, wherein the judgment unit judges whether the candidate for modifier includes a comma, and when judging that the candidate for modifier does not include the comma, judges whether there exists the relationship of modification between the candidate for modifier and the target clause.

12. The translation assistance device according to claim 11, wherein the output unit outputs, when the judgment unit judges that the candidate for modifier includes the comma, information about the size increase which is not possible any more in the opposite direction.
