Syntax evaluation apparatus, translation apparatus, syntax evaluation method, and syntax evaluation program

摘要

A translation apparatus that can perform translation based on a correct syntax, a syntax evaluation apparatus employed in the translation apparatus, a syntax evaluation method, and a syntax evaluation program are provided. A syntax evaluation unit 13 includes a grammatical element guessing part 131 that guesses a grammatical element that should be connected before and after or after a word string indicated by first fragment data, and a grammatical element complementing part 132 that complements, based on the guessing result of the grammatical element guessing part 131, the first fragment data as necessary to generate second fragment data. When the grammatical element guessing part 131 guesses a grammatical element, the grammatical element complementing part 132 complements, at a location to which the grammatical element of the word string indicated by the first fragment data should be connected, a tag indicating the grammatical element in order to generate the second fragment data. When the grammatical element guessing part 131 does not guess a grammatical element, the grammatical element complementing part 132 handles the first fragment data as the second fragment data.
