We perform this in a manner similar to<cite> Klein and Manning (2003)</cite> and Matsuzaki et al. (2005) Our mechanism lays out the unmarkovized intermediate rules in the same way, but we mostly use our clustering scheme to reduce sparsity. We do so by aligning the labels contained in the intermediate nodes in the order in which they would be added when increasing the markovization hori-1 The implementation we use was created by Mark Johnson and used for the research in (Johnson, 1998) .
