In recent years, Machine Translation has shown promising results and received much interest of researchers. Two approaches that have been widely used for machine translation are Phrase-based Statistical Machine Translation (PBSMT) and Neural Machine Translation (NMT). During translation, both approaches rely heavily on large amounts of bilingual corpora which require much effort and financial support. The lack of bilingual data leads to a poor phrase-table, which is one of the main components of PBSMT, and the unknown word problem in NMT. In contrast, monolingual data are available for most of the languages. Thanks to the advantage, many models of word embedding and cross-lingual word embedding have been appeared to improve the quality of various tasks in natural language processing. The purpose of this thesis is to propose two models for using cross-lingual word embedding models to address the above impediment. The first model enhances the quality of the phrase-table in SMT, and the remaining model tackles the unknown word problem in NMT. Publications: ?
