Abstract
The state-of-the-art system combination
method for machine translation (MT) is
the word-based combination using confu-
sion networks. One of the crucial steps in
confusion network decoding is the align-
ment of different hypotheses to each other
when building a network. In this paper, we
present new methods to improve alignment
of hypotheses using word synonyms and a
two-pass alignment strategy. We demon-
strate that combination with the new align-
