Abstract:
|
In this paper we address the problem of
translating between languages with word
order disparity. The idea of augmenting
statistical machine translation (SMT) by
using a syntax-based reordering step prior
to translation, proposed in recent years, has
been quite successful in improving translation
quality. We present a new technique
for extracting syntax-based reordering
rules, which are derived through a syntactically
augmented alignment of source
and target texts. The parallel corpus with
reordered source side is then passed to an
N-gram-based machine translation system
and the obtained results are contrasted with
a monotone system performance. In experiments,
we show significant improvement
for the Chinese-to-English translation task. |
