【摘要】：2009年版的中国科技期刊引证报告(核心版)新提出了一个权威因子指标,权威因子的计算采用的是Prestige Rank算法,PrestigRank算法是在著名搜索引擎算法PageRank算法的基础上修改优化而成的,PrestigeRank算法专门针对期刊引用网络缺失严重提出了合理的解决方案,在权威因子的计算中,期刊之间的引用不再是同等对待,重要期刊的一次引用比次要期刊的一次引用要被赋予更高的权重。利用PrestigeRank算法计算2008年的中国科技论文与引文数据库(CSTPCD)的所有期刊的权威因子,并对权威因子与总被引频次进行了比较研究,发现总被引频次在一定程度上是流行性测度,而权威因子在更大程度上是权威性测度。我们也发现权威因子能部分消除因为学科规模和性质不同造成的被引机会的不同的影响。
[Abstract]:The 2009 edition of the citation report of Chinese Sci-tech Journals (Core Edition) puts forward a new authoritative factor index.The authority factor is calculated by Prestige Rank algorithm and PrestigRank algorithm, which is modified and optimized on the basis of the famous search engine PageRank algorithm. The Prestige Rank algorithm specially proposes a reasonable solution to the serious lack of periodical citation network.In the calculation of authoritative factors, citations between journals are no longer treated equally, and one citation of important journals is given a higher weight than that of secondary journals.The PrestigeRank algorithm is used to calculate the authoritative factors of all journals in China Science and Technology papers and citation Database (CSTPCD) in 2008, and a comparative study is made between the authoritative factors and the total cited frequency. It is found that the total cited frequency is a measure of epidemic to some extent.Authority factor is authority measure to a greater extent.We also find that the authority factor can partly eliminate the different influence of the cited opportunity caused by the different scale and nature of the subject.
