传统影响因子(JIF)只考虑期刊短期内(2年)的数据、可靠性影响因子(即R-影响因子)未考虑相邻年份期刊JIF数据以及基于贝叶斯理论的后验影响因子(IFPI)没有考虑较长时间内期刊的数据。针对以上各因子都易受到人为因素控制这一现象,提出一种结合IFPI和R-影响因子两者优点的新影响因子,即R-后验影响因子(RIFPI)。RIFPI是在IFPI基础上引入期刊的被引半衰期,考虑较长期的数据,从而有效削弱人为因素所带来的影响,进而有利于提高对期刊的评价度。此外,还利用此新因子对JCR中物理学领域34种JIF>3.0的期刊进行实证分析,发现RIFPI与IFPI和JIF相比,其不但能描述期刊被引寿命,而且还能描述期刊中被发表的论文的被引率。
The JIF considers only the journal’s short-term (2 years) data. The reliability factor (ie, R-factor) does not consider JIF data from journals of adjacent years and the IFPI based on Bayesian theory ) Did not consider the data for longer period journals. In view of the fact that all the above factors are easily controlled by human factors, a new influencing factor that combines the advantages of both IFPI and R-factor, namely R-posterior influencing factor (RIFPI), is proposed. RIFPI introduces the cited half-life of journals on the basis of IFPI, and considers the longer-term data, so as to effectively weaken the impact of human factors, which in turn helps to improve the evaluation of journals. In addition, this new factor is used to empirically analyze 34 journals with JIF> 3.0 in the field of physics in JCR and found that RIFPI can not only describe the cited life expectancy of journals, but also the published journals The rate of dissertation cited.
