题目:TOPK: A New Bipartite Ranking Algorithm for Enterprise Social Network
摘要:Abstract
Social networks bring us new perspectives and tools to rethink and solve the traditional problems in the field of enterprise business. Enterprise social network is presented to utilize the main factors in business comprehensively, like enterprises, employees and products. Based on the enterprise social network model we present TOPK algorithm to rank manufacturers and suppliers at the same time, which is improved on PageRank and HITS.Then we give the theoretical effect analysis and convergence analysis on three algorithms. In addition we propose a method to recommend potential enterprise partners using TOPK to improve the accuracy. Then we perform the experiments on the dataset of China automobile supply network. Two evaluation methods are introduced to evaluate the results of enterprise rank. One method is based on the reliable public enterprise rank data, and another is to compare the results of clustering according to the enterprise rank. Through the two methods, our experiment results indicate that TOPK is better than the other two algorithms at ranking enterprises. And enterprise rank from TOPK reflects more on enterprise quality than sales volume.
