【摘要】：学者学术影响力评价成为文献计量学中一个重要的组成部分。我们知道,现在无论是学术奖项的评选、高校老师学术项目的申请等关系到学者切身利益的东西,很大程度上都是取决于学者的学术影响,而如今,学术影响力往往用计量指数来进行衡量。所以,一个好的学术贡献评价指数能够帮助机构对学者作出更为公正的评价。同时,一个好的评价指数,可以充分地对学者进行学术研究激励,对营造一个好的学术氛围,推动研究领域健康发展有重要意义。本文首先对文献计量学的发展以及现状进行了介绍,然后重点对文献计量学指数,尤其是对h指数与h族指数的概念、应用以及优缺点作了详细的阐释。然后本文通过运用在引文曲线上进行信息提取,并将多个信息点进行融合,提出一个单一评价指数——hc指数。为验证hc指数在对学者影响力评价上面的有效性,本文进行了实例研究。我们选取h指数排名前50的西班牙心理学家为研究对象,先将50名学者分别基于h指数和hc指数的排名进行比较分析,发现较h指数而言,hc指数可以很好地将h指数无法区分的学者区分开来。同时发现这两个指数高度相关,为hc指数的应用提供了理论支持。然后用类似方法对这50名学者基于含上述2个指数在内的9个不同指数的排名进行分析,发现发文量和平均单篇被引次数指数对学者影响力的评价效率最低,hc指数因其在信息熵以及同其他指数的相关关系上表现均不错,可认为是一个能较为有效地对学者学术影响力作出评价的单一指数,能弥补h指数在评价时区分度不足的问题。
[Abstract]:The evaluation of scholars' academic influence has become an important part of bibliometrics. We know that now, whether it is the selection of academic awards or the application of academic programs by university teachers, which is related to the immediate interests of scholars, to a large extent, it depends on the academic influence of scholars, and now, Academic influence is often measured by measuring indices. Therefore, a good academic contribution evaluation index can help institutions to make a more fair evaluation of scholars. At the same time, a good evaluation index can fully stimulate the academic research of scholars, and it is of great significance to create a good academic atmosphere and promote the healthy development of the research field. In this paper, the development and present situation of bibliometrics are introduced, and then the concepts, applications, advantages and disadvantages of bibliometrics index, especially h index and h family index, are explained in detail. Then, by using the citation curve to extract information and fuse several information points, a single evaluation index, hc index, is proposed in this paper. In order to verify the effectiveness of HC index in evaluating the influence of scholars, this paper carries out a case study. We selected the top 50 Spanish psychologists in the h index as the research subjects. We compared and analyzed 50 scholars based on h index and HC index respectively. It is found that the H _ c index can well distinguish the scholars whose h index is indistinguishable from the h index. At the same time, it is found that the two indices are highly correlated, which provides theoretical support for the application of the HC index. Then using a similar method to analyze the rankings of the 50 scholars based on nine different indexes, including the two indexes mentioned above. It is found that the index of the number of papers and the average number of citations has the lowest evaluation efficiency on the influence of scholars because of its good performance in the information entropy and the correlation with other indexes. It can be considered as a single index which can evaluate the academic influence of scholars effectively, and can make up for the insufficient differentiation of h index in evaluation.
