【摘要】：【目的】分析基础学科期刊论文被引的分布特点,探究低被引论文区间的界定和评价方法。【方法】以科学引文索引(Wo S)收录的65种凝聚态物理学期刊(CMJ)的被引数据为研究对象,以统计学原理和文献计量学方法,比较分析h指数核心区、被引频次小于篇均被引次数论文,以及最低被引论文的累计被引频次为期刊总被引频次的5%,10%和20%区域内论文的被引特性,以此确定CMJ最合理的低被引区。【结果】CMJ整体零被引率仅为10%,可视为高质量的期刊集合。最低被引论文的累计被引达到总被引频次20%的区域和被引小于篇均被引次数的区域具有被界定为低被引区的统计学依据。零被引率、低被引率和低被引密度与传统评价指标IF、h指数、篇均被引次数以及可被引论文数、总被引频次不存在强相关性,满足作为独立评价指标的充分条件。【结论】由零被引率、低被引率和低被引密度构成复合指标Evel{rN0,rN x,rTci x}用于描述期刊的低被引特性;由h指数和特定区域内的篇均被引次数构成另一个复合指标Evel{h,Ci 20%,Ci cipp,Ci h}用于比较期刊的被引结构特征。研究表明期刊被引结构可以构形分类,而评价参数在不同被引区域有可能存在竞争优势;因此评价期刊的低被引情况要以分析被引结构为前提。期刊的综合评价应该使用多参数多维度指标。
[Abstract]:[objective] to analyze the distribution of citations in journals of basic disciplines, and to explore the methods of defining and evaluating the interval of low citation papers. [methods] Citation data of 65 condensed matter physics journals (CMJs) collected by Wo S) were taken as research objects. Based on the statistical principle and bibliometrics, this paper compares and analyses the core region of h index, and the frequency of citation is less than the number of papers cited. And the cumulative citation frequency of the lowest cited papers was 5% of the total citation frequency of the journal and the citation characteristics of the papers in the region of 20% and 10% of the total cited frequency. [results] the global zero citation rate of CMJ is only 10, which can be regarded as a collection of journals of high quality. The accumulative citation of the lowest cited papers reaches the total citation frequency of 20% and the citation is less than that of the papers. The region of the number has a statistical basis defined as a low cited area. Zero citation rate, Low citation rate and low citation density have no strong correlation with IFH index, citation times and the number of cited papers, which satisfy the sufficient conditions of independent evaluation. [conclusion] the citation rate is zero. The compound index of low citation rate and low citation density Evel {rN0rN xrTci x} is used to describe the low citation characteristics of periodicals. Another compound index, Evel {HCi 20, is used to compare the citation structure characteristics of periodicals, which is composed of h index and the number of citations in a particular region. The results show that the citation structure of periodicals can be classified into configuration and classification. The evaluation parameters may have a competitive advantage in different cited regions, therefore, the low citation of the evaluation journals should be based on the analysis of the cited structure, and the comprehensive evaluation of periodicals should use multi-parameter and multi-dimensional indicators.
