Abstract

This paper describes our submissions, cmu-heafield-combo, to the ten tracks of the 2011 Workshop on Machine Translation's system combination task. We show how the combination scheme operates by flexibly aligning system outputs then searching a space constructed from the alignments. Humans judged our combination the best on eight of ten tracks.
