PageRank用于在共同引文网络中对作者进行排名

PageRank for ranking authors in co-citation networks

Ying Ding, Erjia Yan, Arthur Frazho, James Caverlee

摘要:

Google的PageRank为信息检索创造了一种新的协同作用,以更好地对网页进行排名。它根据图的拓扑结构和节点的权重对文档进行排名。PageRank极大地推动了信息检索领域的发展,并使Google在搜索引擎市场上领先于竞争对手。它已被部署在文献计量学,以评估研究的影响,但很少有这些研究集中在阻尼因子(d)的重要影响排名的目的。本文研究了PageRank算法中不同的阻尼因子如何为作者共同引文网络中作者的排名提供额外的见解。此外,我们提出加权PageRank算法。选取1970 - 2008年信息检索领域108位最高被引作者,构建作者共引文网络。我们根据PageRank计算这108位作者的排名,阻尼因子范围从0.05到0.95。为了测试这些不同指标之间的关系,我们将PageRank和加权PageRank结果与引文排名,h指数和中心性指标进行了比较。我们发现,在我们的作者合作引文网络,引文排名是高度相关的PageRank的不同阻尼因子,也与不同的PageRank算法;引文排名和PageRank不显着相关的中心性措施;和h指数是不显着相关的中心性措施。

英文摘要:

Google's PageRank has created a new synergy to information retrieval for a better ranking of Web pages. It ranks documents depending on the topology of the graphs and the weights of the nodes. PageRank has significantly advanced the field of information retrieval and keeps Google ahead of competitors in the search engine market. It has been deployed in bibliometrics to evaluate research impact, yet few of these studies focus on the important impact of the damping factor (d) for ranking purposes. This paper studies how varied damping factors in the PageRank algorithm can provide additional insight into the ranking of authors in an author co-citation network. Furthermore, we propose weighted PageRank algorithms. We select 108 most highly cited authors in the information retrieval (IR) area from the 1970s to 2008 to form the author co-citation network. We calculate the ranks of these 108 authors based on PageRank with damping factor ranging from 0.05 to 0.95. In order to test the relationship between these different measures, we compare PageRank and weighted PageRank results with the citation ranking, h-index, and centrality measures. We found that in our author co-citation network, citation rank is highly correlated with PageRank's with different damping factors and also with different PageRank algorithms; citation rank and PageRank are not significantly correlated with centrality measures; and h-index is not significantly correlated with centrality measures.
