First Steps Towards Coverage-Based Sentence Alignment
May 2016
In this paper, we introduce a coverage-based scoring function that
discriminates between parallel and non-parallel sentences. When plugged
into Bleualign, a state-of-the-art sentence aligner, our function
improves both precision and recall of alignments over the originally
proposed BLEU score. Furthermore, since our scoring function uses Moses
phrase tables directly we avoid the need to translate the texts to be
aligned, which is time-consuming and a potential source of alignment
errors.
