WebDec 11, 2014 · Pržulj et al. (2004) described an approach focused on small induced subgraphs called graphlets. Owing to combinatorial explosion, such analysis is usually limited to the 30 graphlets with 2–5 nodes ( Fig. 1 ). The number of appearances of graphlets in the network provides a description of the network’s structural properties. Graphlet degree vectors (signatures) and signature similarities were applied to biological networks to identify groups (or clusters) of topologically similar nodes in a network and predict biological properties of yet uncharacterized nodes based on known biological properties of characterized nodes.
