Effective Search of Logical Forms for Weakly Supervised Knowledge-Based Question Answering
An operator predictor constrains the logical-form search space, increasing search success and reducing spurious logical forms, which improves semantic parser training and lifts CSQA KBQA accuracy from 67% to 72%.
