| 摘 要： | 本文在对网络结构挖掘的两种典型算法(HITS算法和PageRank算法)进行比较分析的基础上,将PageRank算法应用到大规模引文网络中.对由236 517篇SCI文章构成的引文网络,计算得到每一篇文献的PageRank值,并深入分析了文献的PageRank值与通常使用的引文数指标之间的关系.分析表明:PageRank值具有与引文数很强的相关性和相似的幂律分布特征,但是PageRank算法能够在高引文文献中更好的区别文献的潜在重要性,并在很大程度上削弱作者自引对文献评价客观性的影响.

| Abstract: | The present study brings the PageRank algorithm into large-seale citation network based on the analysis of the characteristics and appropriateness of HITS algorithm and PageRank algorithm.After calculating the PageRank values of 236,517 articles in the citation network,the authors analyze the relationships between PageRank values and citations.It is indicated that PageRank values and citations have strong correlations and similar Power-Law distribution.However,the PageRank algorithm could better distinguish... |
