From Plank (2011)[1]: "... supported by the results of Rimell and Clark (2008)[2]. They found that, for parser performance, retraining the PoS tagger accounted for a greater proportion of the improvement on the biomedical data, while retraining the supertagger (that includes subcategorization information) was more beneficial for the questions domain. Thus, intuitively, they argue that the main difference between newspaper and biomedical text is in vocabulary, while the main difference between newspaper text and questions is syntactic."
