Idiom and collocation, bilingually redefined for machine translation, are two kinds of phrase in our approach. Idioms are any bilingual expression pairs to solve their structural differences, and collocations are grammatically-related word pairs with target words as mutual determinants of pairwise translation.
Translation dictionary provides amount of knowledge of bilingual idioms and collocations.
Before global parsing of a sentence, idioms are recognized without ambiguities and translated without structural transfers. Idiom recognition segments the sentence, and it makes global parsing very efficient. Collocated word pairs are translated after parsing. Experimental results in English-Korean machine translation, quite different two natural languages, shows that some ambiguities can be resolved efficiently and the quality of machine translation can be enhanced by this approach.
