  abstract  = {We propose a new approach to PoS tagging where in a first step, we assign a
	coarse-grained tag corresponding to the main syntactic category.
	Based on this high-precision decision, in the second step we utilize specially
	trained fine-grained models with heavily reduced decision complexity.
	By analyzing the system under oracle conditions, we show that there is a quite
	large potential for significantly outperforming a competitive baseline.
	When we take error-propagation from the coarse-grained tagging into account,
	our approach is on par with the state of the art.
	Our approach also allows tailoring the tagger towards recognizing single word
	classes which are of interest e.g. for researchers searching for specific
	phenomena in large corpora.
	In a case study, we significantly outperform a standard model that also makes
	use of the same optimizations.},
