What it does Any of the sentences Kim kissed Pat. Pat was kissed by Kim. Is mapped into the set of relationships subj(kiss_0, Kim) obj(kiss_0, Pat) inheritance(kiss_0, kiss)
How the semantic mapping rules look like The rule by($x, $y) & inheritance($x, transitive_event) subj($x, $y) Maps the relex-produced relationship by(prevention, inhibition) Into the abstract conceptual relationship subj(prevention, inhibition) Which is suitable for inference by PLN.
