While Hwa et al. (2005) requires full projected parses to train their parser,<cite> Ganchev et al. (2009)</cite> and Jiang and Liu (2010) can learn from partially projected trees. However, the discriminative training in<cite> (Ganchev et al., 2009</cite> ) doesn't allow for richer syntactic context and it doesn't learn from all the relations in the partial dependency parse.
