Method of creating bilingual dictionary and co-occurrence dictionary for machine translation system

摘要

PURPOSE:To realize a function to learn the bilingual relation and the co-start relation by using a bilingual dictionary to identify the corresponding relation of word levels between a sentence of a 1st language and a translated sentence of a 2nd language. CONSTITUTION:The Japanese and English words are defined as the 1st and 2nd languages respectively. Then a sentence is first is divided into words by reference to a Japanese dictionary, and then the sentence is divided into words by reference to an English dictionary. Then the corresponding relation is identified between the Japanese and English words by reference to a bilingual dictionary. Then the corresponding relation that could not be identified in the preceding step is estimated only in case the simplest estimation is possible. The syntax structures and the meanings are analyzed to the Japanese sentences for extraction of the co-start relation of words. Then the co-start relation of Japanese words obtained in the preceding step is mapped to the co-start relation of the English words. Thus it is possible to realize a function to learn the bilingual relation and the co-start relation of words from the translated sentences.
