We propose a novel approach to translating from a morphologically complex language. Unlike previous research, which has targeted word inflections and concatenations, we fo- cus on the pairwise relationship between mor- phologically related words, which we treat as potential paraphrases and handle using para- phrasing techniques at the word, phrase, and sentence level. An important advantage of this framework is that it can cope with deriva- tional morphology, which has so far remained largely beyond the capabilities of statistical machine translation systems. Our experiments translating from Malay, whose morphology is mostly derivational, into English show signif- icant improvements over rivaling approaches based on five automatic evaluation measures (for 320,000 sentence pairs; 9.5 millio...
