- Abstract:
-
The high computational complexity of existing link prediction algorithms makes them unsuitable for link prediction on large-scale graphs. To solve this problem, we propose a novel link prediction approach that involves combining the existing link prediction approaches with graph sketch approximation. Our proposed approach reduces the computation complexity of link prediction from O(n3) to O(n2k2log2n) Furthermore, to enhance the efficiency of our approach; we also provide a parallel link prediction algorithm, which is implemented on the parallel computing framework Apache Spark. Finally, we conducted extensive experiments on a real network dataset to test the validation and efficiency of our approach. The experimental results indicate that our methods can effectively improve the efficiency of link prediction while guaranteeing prediction accuracy as well.
