... Using One Pivot Language This section describes the translation results by using only one pivot language. For the language pair French and Spanish, we use English as the pivot language. The ... Than One Pivot Language For French to Spanish translation, we also intro- duce German as a pivot language besides English. Using these two pivot languages, we build two dif- ferent pivot models, ... performance of statistical translation systems. To solve this problem, this paper proposes a novel method for phrase-based SMT by using a pivot language. To perform translation between languages...
