In many natural language applications, there is a need to enrich syntactical parse trees. We present a statistical tree annotator augmenting nodes with additional information. The anno- tator is generic and can be applied to a va- riety of applications. We report 3 such ap- plications in this paper: predicting function tags; predicting null elements; and predicting whether a tree constituent is projectable in ma- chine translation. Our function tag prediction system outperforms significantly published re- sults.
