摘　　要：为了更好的度量标准文献的重要性,现将PageRank算法引入到标准引用网络中,但算法在计算标准文献重要性时仅根据出度数来平均分配PageRank值,在一定程度上影响了标准文献重要性的度量。为此提出了一种StandardRank算法来改进PageRank算法,在计算标准文献重要性时用标准文献重要性比例来代替平均分配,并且根据标准引用网络自身的结构特征修改了阻尼系数。实验结果表明:Standard Rank算法在度量标准文献重要性时具有更好的效果。In order to measure the importance of standard literature better,the PageRank algorithm was intro-duced into the standard citation network,but PageRank value was evenly distributed based only on out-degree in calculating the importance of standard literature,which,to a certain extent,affects the measurement of importance of standard literature. Therefore, StandardRank algorithm, which calculates the importance of standard literature with importance proportion,was proposed to improve the PageRank algorithm. This algorithm modified the damp-ing coefficient according to the structure characteristics of the standard citation network. The experimental results show that the StandardRank algorithm works better in measuring the importance of standard literature.
