Two judges discriminated benefactive from non- benefactive PPs for 500 tokens, randomly selected from the parser's output. Only...

We generated unary rules from each LexPar rule based on a manually constructed mapping from FrameNet grammatical functions ... entailment rules solely from the information contained in FrameNet. Our experiment showed that FRED’s rules perform substantially better than LexPar, the only prio...

... 4 Acquiring Transfer Rules This section describes the procedure for deriving transfer rules from aligned parse trees. First, the best-scoring alignment is recovered from the Children-Pairing ... scoring alignment, we acquire transfer rules from that alignment. When more than one pair of trees tie for the highest score, we acquire transfer rules from the set of pairs of a...
