We describe for dependency parsing an an- notation adaptation strategy, which can au- tomatically transfer the knowledge from a source corpus with a different annota- tion standard to the desired target parser, with the supervision by a target corpus an- notated in the desired standard. Further- more, instead of a hand-annotated one, a projected treebank derived from a bilin- gual corpus is used as the source cor- pus. This benefits the resource-scarce languages which haven’t different hand- annotated treebanks. Experiments show that the target parser gains significant im- provement over the baseline parser trained on the target corpus only, when the target corpus is smaller.
