As an example, one of the best performing is the measure proposed by Jiang and Conrath (1997) (similar to the one proposed by (Lin, 1991)), which finds the shortest path in the taxonomic hierarchy between two candidate words before computing similarity as a function of the information content of the two words and their lowest common subsumer in the hierarchy.
these edges are uni-directional; no edges are created from a Synset to a tokenPOS that can represent the Synset.
