Naturally, in some cases a KB constant is not semantically similar to any utterance word (e.g., the relation Field in Figure 1), which we will mediate by using a global inference procedure (Section 3.5).
our goal is to learn a model that given an abstract utterance-logical form pair (x abs , z abs ) produces an alignment matrix A, where A ij corresponds to the alignment probability p(x abs j | z abs i ).
