algorithm algorithm Semantic Similarity Measures Semantic Similarity Measures- Four methods proposed by Resnik[Philip, 1999], Jiang[Jiang and Conrath, 1997], Lin[Lin, 1998] and Schlicker[Schlicker et al., 2006] respectively have presented to determine the semantic similarities of two GO terms based on the annotation statistics of their common ancestor terms. Wang [Wang et al., 2007] proposed a new method to measure the similarities based on the graph structure of GO.
