... permuting children of every tree nodes in Te. We use children to denote direct de-scendants of tree nodes for constituent trees; while for dependency trees, children of a node include notonly ... this line of work andaddress the problem of word reordering based onsource syntactic parse trees for SMT. Similar to mostprevious work, our approach tries to rearrange thesource tree nodes ... into sub-tasks, in which we onlyneed to determine the order of children nodes for all non-leaf nodes in the source parse tree. For a tree node t with children {c1, c2, . . . , cn}, we re-arrange...
