For example, as shown in Figure 1(a), the two Chinese words " 2 " and " 5 " are aligned to the two English words "did 3 " and "things 1 ", and the dependency "things 1 did 3 " is included in the source tree.
we project the dependency into the target side and add a dependency " 2 5 " into the projected structure, as shown in Figure 1(b).
