[시사매거진] Clarivate has released an update to its Journal Citation Reports (JCR)™ for 2022.
Published annually, JCR enables the research community to evaluate the world’s leading journals based on a variety of journal citation indicators, utilization data and visualizations. JCR empowers academic publishers around the world to understand the academic impact of their journals on their field of study and promote their journals to the research community.
This year’s presentation reveals an ever-growing influence of citations in journals in the fields of general medicine, intensive care units, public health, epidemiology, immunology and basic biomedical medicine.
This year, the Lancet received a Journal Impact Factor™ (JIF) of 202.731, beating the New England Journal of Medicine, which took the top spot since its first JCR listing 45 years ago, in the general and medical journal categories. took first place. Three of the ten most cited articles in 2021 were listed in the Lancet. All three of these articles have been linked to COVID-19.
Nature was honored as the first journal to receive more than 1 million citations in one year. In the 2022 JCR, Nature has a total of 16 papers with more than 500 JIF citations, of which 12 were research results related to COVID-19.
Seven journals received more than 100 JIFs for the first time, and all of these journals have published numerous research papers related to COVID-19. Journal of the American Medical Association, Lancet, Lancet Respiratory Medicine, Nature Reviews Drug Discovery, Nature Reviews Immunology ), Nature Reviews Molecular Cell Biology and New England Journal of Medicine.
To preserve the objectivity of the journal selection and the integrity of the report, Clarivate excluded three journals from this year’s JCR, which accounted for 0.01% of the total journals (which did not presume or accuse them of misconduct). Clarivate excludes journals of cases of excessive self-citation or artificial citations (Citation-stacking) through monitoring. Methodology and Variables for Impact of Self-Citation on JCR Indicators were updated in 2020 to better account for discipline/norm, and excluding a journal from the JCR is not the same as deleting it from the Web of Science Core Collection list.
This year, the Clarivate editorial integrity team identified a new type of anomalous citation behavior: self stacking. Self stacking is the act of a journal to increase its JIF by including one or more abnormally high citation papers. Since this year is the year that Clarivate officially defined the exclusion field of self-stacking, this year, the journal will not be excluded from the JIF, and a warning letter will be sent. Journals in which self-stacking behavior is discovered in the future are excluded from JIF. Clarivate will continue to monitor the content with the goal of developing additional screening techniques for JIF distortion.
