Although semi-supervised approaches have been shown to reduce the need for manual annotation (Freitag, 2004; Miller et al., 2004; Ando and Zhang, 2005; Suzuki and Isozaki, 2008; Lin and Wu, 2009; Turian et al., 2010; Dhillon et al., 2011; <cite>Täckström et al., 2012)</cite> , these methods still require a substantial amount of manual annotation for each target language.
