【摘要】：[目的 /意义]针对P指数不能反映评价对象引文分布的P缺陷,在P指数研究的基础上,提出基于引文分布的指数计算方法。[方法 /过程]引入发文-引文分布曲线和学术矩阵表征期刊的引文分布,利用期刊评价的非参数统计方法,通过将引文数据进行分区划分,基于P核和P尾内有引用的论文,采用期刊的平均引文率代表零引用论文的影响,重新定义P指数的计算方法,提出P_(new)指数。为避免学科差异对期刊评价的影响,以仅属于Web of Science数据库中电子电气工程类目下有5年影响因子的53种期刊为研究对象,分别统计期刊的影响因子、5年影响因子、H指数、P指数、P_(new)指数等指标,并进行相关性及差异性分析,以验证P_(new)指数评价的科学性和有效性。[结果 /结论]结果表明,P_(new)指数与H指数、P指数等多个关键指标的相关性较好。与P指数相比,P_(new)指数既延续了其高灵敏度与高区分度的特点,又对P指数相差无几但引用分布大不相同的期刊有更好的显示度和辨识度,而且能够矫正引文分布对P指数评价的偏差。
[Abstract]:[objective / significance] in view of the P defect that P index can not reflect the distribution of citation of the evaluation object, on the basis of the study of P index, An index calculation method based on citation distribution is proposed. [method / process] introducing the distribution curve and academic matrix to characterize the citation distribution of journals, and using the non-parametric statistical method of periodical evaluation. By partitioning citation data, based on the cited papers in P core and P tail, the average citation rate of journals is used to represent the influence of zero citation papers, and the calculation method of P index is redefined. In order to avoid the influence of subject differences on periodical evaluation, 53 journals which belong to the category of electronic and electrical engineering in Web of Science database are studied. The influence factors of periodicals, the 5-year influencing factors and the P index were analyzed respectively, and the correlation and difference were analyzed. In order to verify the scientific and validity of the evaluation of PSP index. [results / conclusions] the results show that the correlation between PSP index and several key indexes, such as H index / P index, is better. Compared with P index, the PSP new index not only extends its high sensitivity. And the characteristics of high differentiation, It also has better indication and identification for journals with similar P index but different citation distribution, and can correct the deviation of citation distribution to P index evaluation.
