Translation of Discontinuous Multi-Word Translation Units in a Korean-to-Japanese Machine Translation System

Due to grammatical similarities, even a one-to-one mapping between Korean and Japanese words (or morphemes) can usually result in a high quality Korean-to-Japanese machine translation. However, multi-word translation units (MWTU), such as idioms, compound words, etc., require n-to-m mapping. Often, the component words of such units do not appear adjacently, which results in a discontinuous MWTU. During translation, the MWTU should be treated as one lexical item rather than as a phrase. In this paper, we investigate units which should be treated as MWTUs in a Korean-to-Japanese MT system, examine discontinuity between their component morphemes, and propose a representation and recognition method, depending on their characteristics. In an experimental evaluation, the proposed method is very effective for handling MWTUs, showing high recall and precision of 99.8% and 99.5% and a fast recognition time.
