The nine types of relations defined on the noun subnetwork, in addition to the synonymy relation that is implicit in each node are: the hyponymy (IS-A) relation, and its inverse, hypernymy; six meronymic (PART-OF) relations -COMPONENT-OF, MEMBER-OF and SUBSTANCE-OF and their inverses; and antonymy, the COMPLEMENT-OF relation.
also, the coefficients reported by Resnik and Lin are actually based on only 28 out of the 30 Miller-Charles pairs because of a noun missing from an earlier version of WordNet.
