Query: Bridge the gap between network-based inference method and global ranking
  method in personal recommendation   In this paper, we study the relationship between the network-based inference
method and global ranking method in personal recommendation. By some
theoretical analysis, we prove that the recommendation result under the global
ranking method is the limit of applying network-based inference method with
infinity times.
