With respect to the focus on function words , our reordering model is closely related to the UALIGN system ( Hermjakob , 2009 ) .
improved word alignment with statistics and linguistic heuristics
Ulf Hermjakob
These related models treat their lexical items as latent variables to be estimated from training data , while our model uses a fixed set of lexical items that correspond to the class of function words . With respect to the focus on function words , our reordering model is closely related to the UALIGN system ( Hermjakob , 2009 ) . However , UALIGN uses deep syntactic analysis and hand-crafted heuristics in its model .
