However, McCloskey et al. (<cite>2006b)</cite> report a drop in performance for their reranking parser when the experiment is repeated in the opposite direction, i.e. with Brown data for self-training and testing, and WSJ data for seed training. In contrast, we report successful in-domain 1 self-training experiments with the BNC data as self-training and test material, and with the WSJ-trained reranking parser used by McCloskey et al. (2006a;<cite> 2006b)</cite> .
