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

摘要

Provided are a translation device capable of performing translation based on correct syntax, a syntax evaluation device, a syntax evaluation method, and a syntax evaluation program applied to the translation device. The syntax evaluation unit 13 estimates a grammar element that should be connected after or before or after the word string indicated by the first fragment data, and the first fragment based on the estimation result of the grammar element estimation unit 131 A grammar element complementing unit 132 that complements the data as necessary to generate second fragment data. When the grammar element estimation unit 131 estimates the grammar element, the grammar element complementation unit 132 complements the tag indicating the grammar element to the position where the grammar element in the word string indicated by the first fragment data should be connected. When the second fragment data is generated and the grammar element estimation unit 131 does not estimate the grammar element, the first fragment data is generated as the second fragment data.
