Secondly, V-TAG is nonlocal in the sense of nonlocal MC-TAG, whereas SN-MCTAG is local, even though the locality is not based on the parent relation in the derivation tree, as is the case in standard local MCTAG, but on the SNdominance relation in the derivation tree.
of the locality, we do not need dominance links (i.e., dominance constraints that have to be satisfied by the derived tree) in SN-MCTAG, in contrast to other TAG variants for scrambling.
