(Shieber et al., 1995), where items are called formula schemata, deduc- tion steps are inference rules, hypothesis are ax- ioms and final items are goal formulas. A parsing schema can be g...

... any of them are correct. Results are shown for increasing values of n. The trends for CLANG and GEOQUERY are different: small values of n show significant im- provements for CLANG, while a larger ... precision, which is important for semantic parsing, it also limits its recall. To generate plenty of candidate SAPTs for reranking, we extended the back-off levels for the parameters...
