费城,2017年6月14日 -- 科睿唯安(原汤森路透知识产权与科技事业部)今天发布了2017年最新《期刊引证报告》(Journal Citation Reports?,简称JCR)。该年度报告为全球最权威最具影响力的学术期刊提供了多纬度的期刊评估指标,包括著名的期刊影响因子(Journal Impact Factor)。作为独立于出版商的机构,科睿唯安自1973年以来发布的JCR,一直基于客观的统计数据来评估期刊在学术文献中的地位。相关分析包括引证数据、影响力指标、以及来自业内领先的涵盖自然科学、社会科学及艺术和人文学科领域的引文索引数据库Web of Science中数以百万计的期刊被引及施引数据。科睿唯安负责研究分析部门的副总裁Emmanuel Thiveaud表示:“因为我们了解学术界对《期刊引证报告》的重视,所以我们将继续致力于保持数据的准确和可靠,一直以来采用严格的选刊标准和无偏见的流程来遴选全球高水平学术期刊并收录到JCR中。”
JCR提供了各种指标对学术期刊进行分析评估——从开放获取(Open Access)到根据不同学科领域对高水平的学术期刊进行排名,进一步帮助出版商、编辑人员和科研人员能够更好地了解和衡量其科研活动在解决诸如全球健康和气候变化等问题上所能产生的影响力。
以气候变化为例:尽管关于气候变化有数以千计的论文发表,但争议仍然挥之不去。为了更清楚地阐述这些研究数据所揭示的内容,JCR列出了关于气候变化的五大研究领域,即环境科学(Environmental Sciences)、气象与大气科学(Meteorology & Atmospheric Sciences)、地学-多学科(Geosciences-Multidisciplinary)、生态学(Ecology)、以及自然地理学(Geography-Physical)。
此外,根据JCR“平均期刊影响因子百分位”,排在这五个学科领域中的前十大期刊是:

*平均期刊影响因子百分位(Average JIF Percentile)根据期刊的排名提供一个标准化的分值,从而对不同学科领域的期刊进行比较  

2017年发布的JCR基于自然科学和社会科学文献在2016年的引用数据,共涵盖81个国家、236个学科的11,459种期刊。其中,共有132种期刊首次获得其影响因子数据;与去年相比,66%的期刊影响因子指标同比有所提高,而33%的期刊有所下降。这些高影响力的学术期刊,在拥有最全面的引文网络、涵盖33,000多种期刊的Web of Science数据库中处于核心地位。


期刊影响因子体现了该期刊2014年和2015年发表的论文在2016年的引文数与期刊在这两年发表的论文数之间的比率。为了确保期刊影响因子在学术界的透明度,今年下半年,Web of Science将提供影响因子比率中作为分母的期刊过去两年发表论文的原始记录的链接入口。除此之外,在明年发布的JCR报告中,还将把这些链接入口中的数据扩展至期刊影响因子比率的分子,即期刊在上一年中的引用数据。


今年发布的JCR还将包含一些增强内容,例如,提供“可引用论文百分比”(Percent Citable Item)以及增加更便于分析的筛选功能。“可引用论文百分比”能够显示出在期刊影响因子计算中被认为“可引用”的文献(即论文和综述)所占的比例。


JCR作为一个模块整合在InCites平台,该平台是基于Web of Science数据的全方位科研绩效分析平台,可以助力衡量科研成果及其影响力,跟踪科研发展趋势,提供文献、期刊、机构和科研人员的对标分析。


此外,“JCR期刊影响因子分区(Journal Impact Factor Quartile)”指标将在本周晚些时候添加到InCites数据库。对于需要评估其科研成果影响力的机构可以利用该指标更好地了解其科研人员在学术界领先的期刊上发表的成果并追踪其变化。

最新版JCR镇压13种期刊(不公布影响因子)

 

按照一贯的政策,运营SCI数据库的科睿唯安(原汤森路透知识产权与科技事业部)持续监控着期刊的发展情况。

相应的处理措施中,最严厉的处理是直接剔除出数据库,比如今年已经将被曝涉嫌从中国市场大肆捞钱的巴西期刊Genetics and Molecular Research从SCI数据库剔除。最近撤稿搞得沸沸扬扬的某刊,现在还在调查中,后续很可能也会遭到类似处理吧。有消息我们再第一时间告诉大家。

相应的处理措施中,相对温和一点的是镇压:即对有可能影响公平的一些信息保持敏感,镇压自引数据较高或互引数据较高的期刊(不公布影响因子),并明确给出相关数据:

Title Suppressions


 

Metrics for the titles listed below are not published due to anomalous citation patterns found in the 2016 citation data. These patterns result in a significant distortion of the Journal Impact Factor and rank that does not accurately reflect the journal’s citation performance in the literature. The Journal Impact Factor provides an important and objective measure of a journal’s contribution to scholarly communication. In the interest of fairness and accuracy for all journals, the distortion of the Journal Impact Factor by an excessive concentration of citations gives rise to the need for suppression. JCR staff will monitor these journals going forward and the titles will be included in a future edition of JCR when the anomalous patterns are resolved. Coverage of these journals in Web of Science and other Clarivate Analytics products is not immediately affected by suppression from the JCR. However, the titles may be subject to review to determine if they continue to meet the quality and publication standards necessary for inclusion in Web of Science. More information on journal suppression is available at:: http://wokinfo.com/media/pdf/jcr-suppression.pdf.

This table lists the categories for each journal (note that each journal may be included in multiple categories), the percentage of citations in the Journal Impact Factor numerator that are self cites, and the distortion in category rank due to self cites. The distortion in category rank is based on analysis of all journals in all categories of the JCR ranked both with and without the inclusion of self cites. Here distortion equals the percentage shift in rank with self cites included versus excluded.

This table lists the recipient and donor journal pairs along with the percentage of citations in the Journal Impact Factor numerator that are from the donor to the recipient (x% of the JIF Numerator cites to Recipient journal from Donor journal). The percentage exchange to the Journal Impact Factor years is the proportion of all citations from donor to recipient (all years) that reference the two years considered in the Journal Impact Factor calculation (x% of all citations from Donor to Recipient were concentrated in the Journal Impact Factor years).
