Illustration of the 2-hop test set configuration. This figure illustrates the configuration of test classes ({c1,c5,c6,c7}∈Ctest in green) in relationship to training classes ({c2,c3,c4}∈Ctrain in blue) in the WordNet hierarchy. Test classes are directly connected to the training classes. This leads to two possible configuration. a On the right, test classes are direct parent of one or more training class: Tr(c1)={c2,c3} and Te(c2)=Te(c3)={c1}. b On the left, test classes are direct children of one training class. There may be one or more children test classes for a given training class: Tr(c5)=Tr(c6)=Tr(c7)={c4} and Te(c4)={c5,c6,c7}
