【摘要】：學術評價工作對于提高研究水平、促進科學發(fā)展具有重大作用。公平規(guī)范的學術評價不僅有利于學術創(chuàng)新,對科研隊伍的壯大和發(fā)展也有一定的激勵作用。目前我國常用的學術評價方法是引文分析法,引文分析法已經衍生出了其他許多的指標來衡量學術影響力,如期刊的影響因子,H指數、W指數等。但傳統(tǒng)學術評價方法存在著諸多弊端,如時間滯后和引用動機不明等。伴隨著Web2.0時代的到來,一方面是學術成果的形式日益豐富;另一方面學術影響力的表現形式也不再局限于被引用,還包括被瀏覽、討論、報道等行為。傳統(tǒng)的評價指標已經無法全面衡量學術成果的影響力,Altmetrics便應運而生。Altmetrics 一經提出便吸引了眾多學者的研究,但大多數研究著重于Altmetrics概念和工具的介紹,實證研究不夠深入和豐富。本文選取綜合性Altmetrics指標Altmetric Attention Score和Mendeley讀者數,研究其與傳統(tǒng)引文指標引用量之間的相關性,并探討這種相關性在學科上是否存在著差異。通過對數據集的篩選分析,本文還重點研究了較高Altmetric Attention Score和較高被引次數之間的關系,試圖探討較高Altmetric Attention Score的論文是否更傾向于獲得更多的被引次數,來分析新型指標對學術評價的意義。研究發(fā)現Altmetrics指標和被引頻次存在著顯著的相關性,并且在學科間存在著顯著的差異。綜合性指標Altmetric Attention Score與被引頻次的相關性較弱。高Altmetric AttentionScore和高被引次數并不存在著顯著相關關系,但在有些學科較高的Altmetric Attention Score論文更傾向于獲得較高的被引次數。基于上述研究結論,我們發(fā)現Altmetric Attention Score衡量的學術影響力與傳統(tǒng)指標并不相同,未來可以根據學科的特點,將Altmetric Attention Score與傳統(tǒng)計量指標相結合來構建一個全面衡量該學科學術成果的指標體系,為學術研究和機構提供更廣闊更具深度的視野。
[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.
