Bold indicates a significant gain over both Direct and Tri-LM for keyword input according to bootstrap resampling (Koehn, 2004)  First, in this section, we examine the effect of the proposed method on accuracy of parsing ambiguous keyword queries.
in Table 3 we show the baseline "Direct" method of training a standard SCFG-based semantic parser, the proposed method without language model verification "Tri-LM," and the proposed method using the Questions language model with NNLM reranking "Tri+LM."
