... reorder- ing model from the weighted alignment matrices. First, we test a simple approach by using the 1-best alignment to generate the reordering model, while using the alignment matrix to produce ... for word alignments that allow multiple alignment hy- potheses, rather than the 1-best alignment (Venu- gopal et al., 2009; Mi et al., 2008; Christopher Dyer et al., 2008). Whil...
