Abstract
Abstract A machine translation apparatus for translating a source language sentence into a target language sentence according to the present invention includes: an analysis unit for analyzing the source language sentence and generating a syntax tree of the source language; a conversion unit for converting the syntax tree of the source language into a syntax tree of the target language; and a generation unit for generating the target language sentence based on the syntax tree of the target language. The machine translation apparatus further includes: a correspondence information storage unit for storing information of correspondence between words in the source language sentence and words in the target language sentence obtained by the generation unit; a positioning unit for determining division positions at which to divide the source language sentence into phrases in the source language based on phrase categories in the syntax tree of the source language generated by the analysis unit; a translated phrase building unit for dividing the source language sentence at the division positions and generating phrases in the target language corresponding to the phrases in the source language; an output formatting unit for generating an output format for displaying the phrases in the source language so that the phrases in the source language correspond to the phrases in the target language; and a display unit for outputting the phrases in the source language and the phrases in the target language onto a display screen.
