6 Of course, symmetrizing Model 4 by intersecting alignments from both directions does yield an improved AER of 6.9, so, while our model does do surprisingly well with cheaply obtained count-based features, Model 4 does still outperform it so far.
our model can 4 It is important to note that while our matching algorithm has no first-order effects, the features can encode such effects in this way, or in better ways -e.g.
