论文摘要
研究领域中有不同的引文习惯，会影响研究文献的过时。我们根据引用的参考分布作为一种同步方法来分析八个科学子场中纪律期刊中研究文献的独特过时。我们同时使用负二项式（NB）和泊松分布来捕获这种过时。所检查的语料库于2019年发布，涵盖了22,559篇论文，引用了872,442篇参考文献。此外，提出了三个分析分布尾巴的措施：（i）引用的参考存活率，（ii）引用的参考死亡率和（iii）引用的参考百分位数。这些措施很有趣，因为分布的尾巴在文档开始过时时收集了引文的行为，因为它很少被引用（使用）。作为主要的结论，即使在同一子场的纪律期刊之间观察到的差异也是如此重要，以至于有必要对引文分布的尾巴使用某种措施，例如本文在适当的方式分析期刊的长期影响时，在本文中提出的差异。
There are different citation habits in the research fields that influence the obsolescence of the research literature. We analyze the distinctive obsolescence of research literature in disciplinary journals in eight scientific subfields based on cited references distribution, as a synchronous approach. We use both Negative Binomial (NB) and Poisson distributions to capture this obsolescence. The corpus being examined is published in 2019 and covers 22,559 papers citing 872,442 references. Moreover, three measures to analyze the tail of the distribution are proposed: (i) cited reference survival rate, (ii) cited reference mortality rate, and (iii) cited reference percentile. These measures are interesting because the tail of the distribution collects the behavior of the citations at the time when the document starts to get obsolete in the sense that it is little cited (used). As main conclusion, the differences observed in obsolescence are so important even between disciplinary journals in the same subfield, that it would be necessary to use some measure for the tail of the citation distribution, such as those proposed in this paper, when analyzing in an appropriate way the long time impact of a journal.
