Our work also has connections to joint parsing (Smith and Smith, 2004;Burkett and Klein, 2008) and bilingually-constrained monolingual parsing (Huang et al., 2009a) because we use another language to resolve ambiguity for one language.
we thank Liang Huang, Hao Zhang, and Tong Xiao for discussions on synchronous binarization, Haitao Mi and Hao Xiong for providing and running the baseline systems, and wenbin Jiang for helping us train parsing models.
