中文摘要：
针对节点收缩法在加权网络节点重要性评估中的缺陷,提出一种改进的加权网络节点重要性评估方法。通过以加权最短距离来定义网络凝聚度和对连边重要性评估网络G＊进行边赋权两个方面的改进,充分考虑边权差异对节点自身重要性和连边重要性的影响。通过对比分析对该改进方法进行了优势分析和有效性验证,通过调节比例系数和权值系数分析了系数对节点重要性和相对重要性评估结果的影响,结果表明该改进方法可以在不增加计算复杂度的情况下对加权网络节点重要性进行更加全面、准确的评估。
英文摘要：
Aiming at the defect from node contraction method in the node importance evaluation of weighted networks,this paper proposed an improved node importance evaluation method in weighted network. Through the two improvements, which were defining the network agglomeration with the weighted shortest distance and weighting the edge importance evaluation network G ＊ , it took full consideration the influence of edge differences over the node importance and edge importance. Based on the a- nalysis of comparative results, it analyzed the advantage of the improved method, verified the validity of the improved method. By regulating the proportionality coefficient and weight coefficient, it investigated the influence of coefficient over node importance and the relative importance. The results show that the improved method can more comprehensively, accurately evaluate the node importance in weighted networks without increasing the time complexity of computation.
