CCG semantics Work on semantic parsing has mapped sentences onto semantic representations with latent CCGs (Zettlemoyer and Collins, 2009;Kwiatkowski et al., 2010;Kwiatkowski et al., 2013) for restricted domains.
the CCGbank dependencies used by Clark and Curran's model constrain all lexical and attachment decisions (only allowing 'spurious' derivational ambiguity) whereas our use of semantic dependencies models most of the syntactic parse as latent.
