... of the system. 742 5 Experiments Our experiments are conducted on Chinese-to- English translation in three SMT systems. 5.1 Baseline Systems The first SMT system is a phrase-based system ... that the boosting-based system combination seems to be more helpful to the phrase-based system than to the Hiero system and the syntax-based system. For the phrase-based system, it yi...

... used the single- best output of each system; this was done be- cause not all systems were providing N-best lists, and an unbalanced inclusion would favor some systems much more than others. Further- more, ... pairwise alignments be- tween system hypotheses (either using ITGs or tercom); for each pair, one of the hypotheses plays the role of the “reference”. • Selection of a system output...
