We describe a simple strategy to achieve trans- lation performance improvements by combin- ing output from identical statistical machine translation systems trained on alternative mor- phological decompositions of the source lan- guage. Combination is done by means of Min- imum Bayes Risk decoding over a shared N- best list. When translating into English from two highly inflected languages such as Ara- bic and Finnish we obtain significant improve- ments over simply selecting the best morpho- logical decomposition.
