Abstract

Link prediction is an important issue in the subject of data mining. The similarity algorithm based on random walk often sets the probability of particles transferring to adjacent nodes to be equal, but ignores the effect of node degree on the transition probability. To solve this problem, this paper proposed a link prediction algorithm based on lowest-degree preference random walk with restart. Firstly, the algorithm redefined the transition probability of the walkers by introducing lowest-degree preference function, then applied it to the random walk with restart, and explored the effect of lowest-degree preference strategy on node similarity. The experimental results of nine real networks show that the proposed method has higher prediction accuracy, and gives more network topology information, which proves that the algorithm has certain advantages in the evaluation of node similarity.
