STIMULATE: Generalized Example-Based Machine Translation

点击翻译按钮获取中文摘要

Example-based machine translation (EMBT) searches a parallel corpus of pre-translated texts for the closest match to each new sentence being translated. Traditional EBMT works well only when there is a very large relevant parallel corpus (e.g. over 200 MB). The proposed investigation extends EBMT by generalizing words into semantic equivalence classes, by syntactic canonicalization of the source and target corpora, and by composing multiple partial matches, rather than selecting a single "best" match. These new methods will be evaluated in at least Spanish-English and Korean-English machine translation. Generalized EBMT promises to produce significantly higher accuracy translations than traditional EBMT, given the same size training corpus, or alternatively produce equivalent-quality translations given an order of magnitude smaller corpus. Combining the inherently brief development cycle of EBMT with the much smaller bilingual corpus requirement, makes generalized EBMT the future technology of choice for rapid deployment of machine translation to new, possibly exotic, language pairs.
