基于ESI科学家计量方法的重新评估     

杨毓丽  单承伟  张苏 《情报杂志》2014,(9)

以ESI排名前5位的经济学家为统计对象,通过选择六种作者贡献率分配算法,对5位经济学家论文总数、总被引频次排名和篇均被引频次三个指标进行了重新评价。研究结果表明：从总被引频次来看,除了Harmonic counting和FLAE排名一致外,其他几种算法的排名完全不同,而且排名的差异非常大。从篇均被引频次来说,六种计量方法排序结果完全一致。  相似文献   

Quantifying the structural and temporal characteristics of negative links in signed citation networks     

《Information processing & management》2022,59(4):102996

Although the citation relationships among papers can help in tracking and understanding the development of knowledge, few studies have noted that the content and sentiments of citations of a paper differ. Here, we use sentiment-labeled citation data to construct a directed signed citation network, in which an author may agree with or criticize the cited paper and these represent different ways of inheriting knowledge. The dataset we use consists of 9,038 papers in the field of Computational Linguistics, including 25,275 citations, with 20.8% positive citations, 8.6% negative citations and 70.6% neutral citations. We systematically quantify the structural patterns of negative citations, impact assortativity of involved papers, occurrence time distribution and consequences of receiving negative attention. Remarkably, we find that papers with different impacts have a similar probability of receiving negative citations, and highly cited papers tend to give negative citations to low-impact papers around but avoid giving negative citations to high-impact papers. Our research also reveals the random occurrence rules and colocation patterns of negative citation distribution. In addition, we show that, in the short term, around 60% of multiple negative citations is positively related to the impact of the cited paper while more than 80% are negatively related to the impact in the long run. Our findings explain the pattern by which negative citations occur and deepen the understanding of negative citations.  相似文献

李向阳  刘小平 《科技管理研究》2016,(6):163-169

以我国在美国专利商标局(USPTO)申请的有机精细化工专利为研究对象,采用非专利引文(Non-patent References,NPRs)分析方法,从多个角度对该领域技术创新与科学研究的关系进行探讨。研究表明,我国有机精细化工领域的技术创新对科学研究有着较强的依赖性,且这种依赖有不断增强的趋势;该领域技术创新所需的科学知识主要来自国际一流期刊,美国、中国、日本等是最主要的来源国家,公共科学为我国该领域的发展提供了重要支撑。  相似文献   

An empirical approach based on quantile regression for estimating citation ageing     

《Journal of Informetrics》2019,13(2):738-750

An aspect of citation behavior, which has received longstanding attention in research, is how articles’ received citations evolve as time passes since their publication (i.e., citation ageing). Citation ageing has been studied mainly by the formulation and fit of mathematical models of diverse complexity. Commonly, these models restrict the shape of citation ageing functions and explicitly take into account factors known to influence citation ageing. An alternative—and less studied—approach is to estimate citation ageing functions using data-driven strategies. However, research following the latter approach has not been consistent in taking into account those factors known to influence citation ageing. In this article, we propose a model-free approach for estimating citation ageing functions which combines quantile regression with a non-parametric specification able to capture citation inflation. The proposed strategy allows taking into account field of research effects, impact level effects, citation inflation effects and skewness in the distribution of cites effects. To test our methodology, we collected a large dataset consisting of more than five million citations to 59,707 research articles spanning 12 dissimilar fields of research and, with this data in hand, tested the proposed strategy.  相似文献   

Mapping the importance of the real world: The validity of connectivity analysis of patent citations networks   总被引：1，自引：0，他引：1  

David Barberá-Tomás  Fernando Jiménez-SáezItziar Castelló-Molina 《Research Policy》2011,40(3):473-486

Recent empirical findings have questioned the use of patent citations as a measure. This points to the need of validation of patent citations methodologies, which we address by testing a recent methodology for studying technological evolution, namely connectivity analysis of citation networks. We find connectivity analysis to be a valid tool to identify the reliable knowledge which opens the way to further technological evolution of a surgical prosthesis, the artificial spinal disc. We also illustrate how connectivity analysis represents how this reliable knowledge differs depending on the stage of technological evolution. The corroborated validity of connectivity analysis of patent citations may trigger a renaissance in the use of this kind of patent data.  相似文献

通过计量指标分析发现操纵期刊评价结果的行为   总被引：1，自引：0，他引：1  

马峥 《编辑学报》2016,28(6):608-611

科学计量指标可以客观反映期刊的质量和影响,是期刊评价和科研管理工作的重要工具,其科学性和有效性的前提是学术期刊坚守出版诚信,尊重知识的原始分布状态和传播过程.一些期刊采取人为调整指标的方式,企图操纵期刊的评价结果.这样的行为可以通过对科学计量指标的分析发现.本文通过对“引导作者增加不必要引用”、“互引”、“在影响因子时间窗口内外调节自引”等行为进行剖析发现:结合使用不同指标能更加客观科学地评估学术期刊的全面情况,操纵指标的行为很容易就被识破和曝光,因此学术期刊办刊人要坚守诚信底线,拒绝尝试弄虚作假.  相似文献
