... rule-interaction problems exemplified by the con- crete collisions were solved by adding • 26 general rules to cover certain standard scope mismatches caused by verb-inversion and negation. • ... particular, the application of sortal constraints expected by predicates of their arguments. Sor- tal constraints cut down on structural (e.g. at- tachment) ambiguity, and on word...

... e J yielded by a derivation D is obtained by concatenating the target phrases of the rules in the order in which they were applied. We define Y (D) to be the target string yielded by D. 532 Now ... constraint we want to apply is that each word written by logic MONOTONE-GENERATE is equal to the word gen- erated by logic NGRAM. We accomplish this by unifying variables e q and e n−i i...
