We compare two pivot strategies for phrase-based statistical machine transla- tion (SMT), namely phrase translation and sentence translation. The phrase translation strategy means that we di- rectly construct a phrase translation ta- ble (phrase-table) of the source and tar- get language pair from two phrase-tables; one constructed from the source language and English and one constructed from En- glish and the target language. We then use that phrase-table in a phrase-based SMT system. The sentence translation strat- egy means that we first translate a source language sentence into n English sen- tences and then translate these n sentences into target language sentences separately. Then, we select the highest scoring sen- tence from these target sentences. We con- ducted controlled experim...
