【摘要】：由于传统文献计量指标的片面性与延时性,引文数量等指标越来越难以评价论文的综合影响力,Altmetrics应运而生。Altmetrics指标常用于论文层面的计量,目前有许多工具可以帮助研究者获取文献的各种Altmetrics指标,研究者能够通过其Altmetrics指标来观测社交媒体等平台对该文献的使用情况。高被引论文是被引频次以及热度较高的论文,具有较高的学术影响力,目前没有完备的评价体系对高被引论文的影响力进行综合评价,高被引论文Altmetrics指标的具体情况及这些指标反映出的社会影响力也不得而知。针对以上情况,为了探索高被引论文的综合评价体系,明确高被引论文的Altmetrics指标情况及社会影响力,为合理评价科研成果提供思考与建议。本文以"社会科学、综合"领域中的top papers为研究对象,通过ESI数据库、Altmetric.com获取"社会科学、综合"领域文献的文章详情、被引频次、Altmetrics指标等数据。本文首先根据学者影响力模型构建高被引论文的影响力评价模型,对高被引论文构建影响力指标体系并将Altmetrics指标进行分层。随后,对这些文献的Altmetrics指标进行特征分析与可用性分析,发现Altmetrics得分能综合反映高被引论文的社会影响力,Altmetrics得分主要跟推荐、引用、讨论三类指标中的典型指标新闻提及数、博客提及数、推文提及数相关,而从统计分析结果及可用性指标来看,政策提及数、Facebook提及数、维基百科引用数、Google+提及数、Mendeley中的阅读数量同样值得关注。然后对高被引论文的被引频次与Altmetrics指标对比分析,发现高被引论文的被引频次与Altmetrics得分等指标相关性不明显,还发现在学术上得到更多关注的是关于理论、研究方法的经典文献,发表时间较新、与生活问题相关的论文会在社交媒体受到更多关注。另外Mendeley中的阅读数量能够一定程度上反映高被引论文的学术影响力。总的来说,由于高被引论文学术影响力与社会影响力的差异较大,传统文献计量指标不能综合反映高被引文献的影响力,其影响力应该由被引频次、Altmetrics指标来综合评价;其社会影响力可以由Altmetrics得分这个综合指标来反映,这个指标主要受新闻提及数、博客提及数、推文提及数这三个指标的影响,这说明这三个指标对高被引论文的社会影响力评价有重要参考价值。另外,除了被引频次,Mendeley中的阅读数量也能反映高被引论文的学术影响力。基于以上结论,本文明确了高被引论文学术影响力与社会影响力的联系以及区别,为高被引论文的影响力评价提供了新的思路,为全面反映高被引论文的综合影响力评价方式提供了可行的策略,也为科研成果的影响力评价提供了清晰的方向。
[Abstract]:Because of the one-sidedness and delay of the traditional literature measurement index, it is more and more difficult to evaluate the comprehensive influence of the paper, such as the number of citations. Altmetrics is often used to measure the paper level. At present, there are many tools to help researchers to obtain a variety of Altmetrics indicators of the literature, researchers can use its Altmetrics index to observe the use of social media and other platforms to the use of the literature. High cited papers are papers with high frequency of citation and high heat, which have higher academic influence. At present, there is no complete evaluation system for comprehensive evaluation of the influence of high cited papers. The specific situation of the Altmetrics indicators and the social impact of these indicators are also unknown. In view of the above situation, in order to explore the comprehensive evaluation system of high cited papers, clarify the Altmetrics index and social influence of high cited papers, and provide some thoughts and suggestions for the rational evaluation of scientific research results. This paper takes top papers in the field of "Social Science, Synthesis" as the research object, obtains the article details of the "Social Science, Synthesis" literature through the ESI database "Altmetric.com", and the cited frequency and other data such as Altmetrics index. Firstly, according to the influence model of scholars, the influence evaluation model of high citation paper is constructed, and the influence index system is constructed and the Altmetrics index is stratified. Then, the characteristic analysis and usability analysis of the Altmetrics index of these documents are carried out. It is found that the Altmetrics score can comprehensively reflect the social influence of the highly cited paper and the social impact metrics score is mainly followed by recommendation, citation, and discusses the number of news references of typical indicators in the three types of indicators. Blog references, tweet references are relevant, and from statistical analysis and usability indicators, policy references count Facebook references, and Wikipedia quotes and Google references to Mendeley are also of concern. Then, by comparing the cited frequency of high cited paper with Altmetrics index, we find that the correlation between cited frequency of high cited paper and Altmetrics score is not obvious, and it is also found that more academic attention is paid to the theory. The classic literature on research methods, published at a relatively new time, will attract more attention on social media. In addition, the amount of reading in Mendeley can reflect the academic influence of high cited papers to some extent. In general, because of the great difference between the academic influence and the social influence of the high cited papers, the traditional bibliometric index can not reflect the influence of the high cited literature comprehensively, and its influence should be comprehensively evaluated by the cited frequency and Altmetrics index. Its social impact can be reflected by a comprehensive index of Altmetrics scores, which is mainly influenced by three indicators: the number of news references, the number of blog references, and the number of tweets. This indicates that these three indexes have important reference value for the social impact evaluation of high cited papers. In addition, the number of readings in Mendeley also reflects the academic influence of high cited papers. Based on the above conclusions, this paper clarifies the relationship and difference between the academic influence and social influence of high cited papers, and provides a new way of thinking for the evaluation of the influence of high cited papers. It provides a feasible strategy for the comprehensive impact evaluation of high cited papers, and provides a clear direction for the impact evaluation of scientific research results.
