bol and L yield (X 0 ) = X. Then, the derivation tree, the derived tree, and the yield of Fig. 2 are represented by: Trees<cite> (Kallmeyer and Kuhlmann, 2012)</cite> 's process to translate derivation trees into dependency trees is a two-step process. The first one does the actual transformation, using macro-tree transduction, while the second one modifies the way to get the yield from the dependency trees rather than from the derivation ones.
