METHOD AND APPARATUS FOR DETECTING ERRORS OF MACHINE TRANSLATION USING PARALLEL CORPUS

摘要

PURPOSE: A machine translation error detection method using the parallel corpus and an apparatus thereof are provided so that by providing an error statistics information classified as for each type the reading mistake generating in the machine translation system of the rule base is detected. The performance of the machine translation system is improved. CONSTITUTION: A part of analyzing morpheme(104) analyzes the morpheme of the purpose language sentence interpreted by machine with the purpose language sentence of the parallel corpus corresponding to the primitive language sentence. It classifies into the word by word. A word by word sorter(106) stands in line the group of the purpose language sentence interpreted by machine and primitive language sentence and the group of the purpose language sentence of the primitive language sentence and parallel corpus to the word by word. It decodes. An error detection part(108) detects error through the comparison of the word by word of the decoded sentences as described above from the purpose language sentence interpreted by machine. It classifies error and the error category and performance analysis part(110) inspect the error pattern ratio. Error data is produced.
