【摘要】：学术评价工作对于提高研究水平、促进科学发展具有重大作用。公平规范的学术评价不仅有利于学术创新,对科研队伍的壮大和发展也有一定的激励作用。目前我国常用的学术评价方法是引文分析法,引文分析法已经衍生出了其他许多的指标来衡量学术影响力,如期刊的影响因子,H指数、W指数等。但传统学术评价方法存在着诸多弊端,如时间滞后和引用动机不明等。伴随着Web2.0时代的到来,一方面是学术成果的形式日益丰富;另一方面学术影响力的表现形式也不再局限于被引用,还包括被浏览、讨论、报道等行为。传统的评价指标已经无法全面衡量学术成果的影响力,Altmetrics便应运而生。Altmetrics 一经提出便吸引了众多学者的研究,但大多数研究着重于Altmetrics概念和工具的介绍,实证研究不够深入和丰富。本文选取综合性Altmetrics指标Altmetric Attention Score和Mendeley读者数,研究其与传统引文指标引用量之间的相关性,并探讨这种相关性在学科上是否存在着差异。通过对数据集的筛选分析,本文还重点研究了较高Altmetric Attention Score和较高被引次数之间的关系,试图探讨较高Altmetric Attention Score的论文是否更倾向于获得更多的被引次数,来分析新型指标对学术评价的意义。研究发现Altmetrics指标和被引频次存在着显著的相关性,并且在学科间存在着显著的差异。综合性指标Altmetric Attention Score与被引频次的相关性较弱。高Altmetric AttentionScore和高被引次数并不存在着显著相关关系,但在有些学科较高的Altmetric Attention Score论文更倾向于获得较高的被引次数。基于上述研究结论,我们发现Altmetric Attention Score衡量的学术影响力与传统指标并不相同,未来可以根据学科的特点,将Altmetric Attention Score与传统计量指标相结合来构建一个全面衡量该学科学术成果的指标体系,为学术研究和机构提供更广阔更具深度的视野。
[Abstract]:Academic evaluation plays an important role in improving the level of research and promoting the development of science. Fair and standardized academic evaluation is not only conducive to academic innovation, but also to the expansion and development of scientific research team. At present, the commonly used method of academic evaluation in China is citation analysis, which has derived many other indexes to measure academic influence, such as the influence factor of journals, H index and W index, and so on. However, there are many disadvantages in traditional academic evaluation methods, such as time lag and cited motives unknown. With the advent of the Web 2.0 era, on the one hand, the form of academic achievements is increasingly rich; on the other hand, the expression of academic influence is no longer limited to being cited, but also includes browsing, discussion, reporting and other behaviors. The traditional evaluation indicators have been unable to measure the impact of academic achievements. Altmetrics has come into being. Altmetrics has attracted many scholars. But most of the studies focus on the introduction of Altmetrics concepts and tools, and the empirical research is not deep and rich enough. This paper selects the comprehensive Altmetrics index Altmetric Attention score and Mendeley number of readers to study the correlation between Altmetric Attention score and the citation quantity of traditional citation index, and discusses whether there is a difference in this correlation in the subject. Through the screening analysis of data sets, the relationship between higher Altmetric Attention score and higher number of citations is also studied in this paper. The author tries to find out whether the papers with higher Altmetric Attention score are more inclined to get more citations. To analyze the significance of new indicators to academic evaluation. It is found that there is a significant correlation between Altmetrics index and citation frequency, and there are significant differences among disciplines. The correlation between Altmetric Attention score and citation frequency was weak. There is no significant correlation between high Altmetric tension score and high citation number, but in some subjects higher Altmetric Attention score papers tend to obtain higher citation times. Based on the above findings, we find that Altmetric Attention score measures academic influence differently from traditional indicators, and can be based on the characteristics of the subject in the future. Altmetric Attention score is combined with traditional measurement index to construct an index system to measure the academic achievement of this discipline in an all-round way, which provides a broader and deeper perspective for academic research and institutions.
