摘要 本文基于自然对数原则,提出了一个用于评估研究人员论文的文献计量新指数,称为x指数。x指数充分考虑了研究人员发表的论文数量,每篇文献的被引次数,以及平均被引次数。为了检验该指数的效果,本文从著名的WOS数据库中提取了68个作者3617条记录,单个作者的论文数在1~462之间,被引次数在4~11558之间,并运用这些记录与本文中提到的指数进行了计算和比较。结果表明,x指数克服了现有指数的缺点,该指数受到研究人员的论文数,文献的总被引次数,平均被引次数,单篇文献的被引次数等因素综合影响,能反映研究人员论文的整体水平,最大的缺点在于无法显示作者的最高被引次数,其它指数也具有这个缺点。 The paper proposes a new bibliometric index to quantify an individual's scientific researcher output and named as x-index. The new index considers sufficiently the number of papers (NP), the times-cited (TO), and the average of a re- searcher. This paper has extracted 3617 records from 68 authors whose TC ranges from I to 462 and NP ranges from 4 to 11558 in Web of ScienceTM, and tries to analyze the sensitivity of the x-index. The results show that it is a sensitive biblio- metric index and overcomes the shortcomings of most existing indices. The new index can be affected by the number of pa- pers, the total citation times, the average of citation times and the citation times of single paper, and can evaluate the scien- tific output of researchers. But the biggest shortcoming of the index is that it cannot be affected by the highest cited times. The index can also be used to evaluate the level of journals.
