We describe our submission to the domain adaptation track of the CoNLL07 shared task in the open class for systems using ex- ternal resources. Our main finding was that it was very difficult to map from the annota- tion scheme used to prepare training and de- velopment data to one that could be used to effectively train and adapt the RASP system unlexicalized parse ranking model. Never- theless, we were able to demonstrate a sig- nificant improvement in performance utiliz- ing bootstrapping over the PBIOTB data.
