We present an approach to training a joint syntactic and semantic parser that com- bines syntactic training information from CCGbank with semantic training informa- tion from a knowledge base via distant su- pervision. The trained parser produces a full syntactic parse of any sentence, while simultaneously producing logical forms for portions of the sentence that have a se- mantic representation within the parser?s predicate vocabulary. We demonstrate our approach by training a parser whose se- mantic representation contains 130 pred- icates from the NELL ontology. A seman- tic evaluation demonstrates that this parser produces logical forms better than both comparable prior work and a pipelined syntax-then-semantics approach. A syn- tactic evaluation on CCGbank demon- strates that the pars...
