APPARATUS AND METHOD FOR CHINESE WORD SEGMENTATION PERFORMANCE IMPROVEMENT USING PARALLEL CORPUS

摘要

The present invention relates to an apparatus and method for improving Chinese word segmentation performance, and more particularly, an apparatus and method for improving word segmentation performance by processing word segmentation errors of Chinese by automatically recognizing an accurate boundary of a word from a sentence of another language, for example, English or Korean, of a parallel corpus of which a word boundary is clear in order to reduce unregistered word errors and ambiguity errors frequently appeared in a Chinese word segmenting device. According to the present invention, a limitation that errors are confirmed from the word segmenting device by consuming lots of manpower and time can be overcome by continuously extracting the unregistered word errors and ambiguity errors, which are difficult to process at the time of word segmentation of a Chinese sentence, through the parallel corpus and storing corrected word segmentation information.
