For the protein-protein interaction network(PPI network)link prediction algorithm Sim based on a similarity measurement,it is proved that the Sim index is based on a 3-hop path index.The analysis indicates that the Sim matrix and PPI network adjacency matrix have strong correlation,providing a theoretical basis for the PPI network link prediction algorithm based on similarity measurement.
