2021 launch delivers expanded content, new Journal Citation
Indicator and revamped user interface
LONDON, June 30, 2021 /PRNewswire/ --
Clarivate Plc (NYSE:CLVT), a global leader in providing
trusted information and insights to accelerate the pace of
innovation, today released the 2021 update to its annual Journal
Citation Reports (JCR)™. The annual JCR release enables the
research community to evaluate the world's high-quality academic
journals using a range of indicators, descriptive data and
visualizations. The reports are used extensively by academic
publishers across the globe to evaluate the impact of their
journals relative to their field and promote them to the research
community.
The JCR is based on 2020 data compiled from the Web of Science
Core Collection™, the flagship collection of quality journals,
books and conference proceedings in the world's largest
publisher-neutral global citation database.
The structured data are curated by the
global team of experts at Clarivate, who continuously evaluate
and select the collections covered to ensure accuracy in
journal impact evaluations. These insights enable researchers,
publishers, editors, librarians and funders to explore the key
drivers of a journal's value for diverse audiences, making better
use of the wide body of data and metrics available in the JCR.
Key highlights for 2021:
- This year's edition includes more than 20,000 journals from 113
countries across five continents and 254 research categories in the
sciences, social sciences, arts and humanities.
- More than 14,000 journals have at least one Gold Open Access
publication, with more than 4,600 being fully Open Access.
- New expanded content : In total, 8,771 journals
have been added to the JCR this year with the expansion of content
across the full Web of Science Core Collection. The Arts &
Humanities Citation Index (AHCI)™ and the Emerging Sources Citation
Index (ESCI)™ will be included in the JCR for the first time this
year, accounting for over 70% more content. With this addition the
JCR's coverage of journal literature will now reflect the full
breadth of research covered in all the journals in the Web of
Science Core Collection.
- New Journal Citation Indicator : Developed by the
Institute for Scientific Information (ISI)™ at Clarivate, this new
metric represents the average category-normalized citation impact
for papers published in the prior three-year period, providing a
single journal-level metric that can be easily interpreted and
compared across disciplines. The Journal Citation Indicator will be
calculated for all journals in the Web of Science Core Collection –
including those that do not have a Journal Impact Factor
(JIF)™.
- New user experience : The 2021 JCR offers a
revamped user interface by which the layered, rich data of the JCR
can be easily and intuitively explored and visualized. New graphics
improve the user experience with simpler, more direct searching
while affording a deeper look into the data. The new interface is
based on extensive user feedback and dual access to the new and old
platforms will be available through the end of 2021.
- Early Access content : The expanded coverage in
this year's release will introduce Early Access articles,
reflecting the earliest availability of new research as it appears
in the 'version of record' prior to official publication.
To support objectivity in journal selection and the integrity of
the reports, Clarivate has suppressed 10 journals from the JCR this
year (without presumption or accusation of wrongdoing),
representing 0.05% of the journals listed. Clarivate monitors and
excludes journals that demonstrate anomalous citation behavior
including where there is evidence of excessive journal
self-citation and citation stacking. The methodology and parameters
for the effect of journal self-citation on JCR metrics were updated
in 2020 to better account for discipline norms. The suppression of
a journal from the JCR does not equate to a de-listing from the Web
of Science Core Collection.
In addition, an Editorial Expression of Concern has been issued
for 11 journals with one or more published items with an atypically
high-value contribution to the JIF numerator and a pattern of
journal citations disproportionately concentrated into the JIF
numerator. Clarivate will continue to review content of this type
with the goal of developing additional screening for distortions of
the JIF.
Keith Collier, Senior Vice
President of Product, Science at Clarivate said: "The carefully
selected and structured data within the JCR allows the research
community to make better informed, more confident decisions with
transparent, publisher-neutral journal intelligence. In 2021, we
are proud to introduce new content, a new UI and the Journal
Citation Indicator, which is designed to complement the JIF – the
original and longstanding metric for journal evaluation – and other
metrics currently used in the research community. These latest
refinements and additions to the journal intelligence platform's
existing store of resources will further support the research
community with trusted insights that can inform decisions and
accelerate the pace of innovation."
Each journal profile in the JCR provides a rich array of journal
intelligence metrics, including:
- The Journal Citation Indicator, which represents the average
category-normalized citation impact for papers published in the
prior three-year period;
- the Immediacy Index, which measures how frequently the average
article from a journal is cited within the same year as
publication;
- the journal's rank in category, determined by Journal Impact
Factor, expressed as a percentile;
- cited half-life, which is the median age, in years, of items in
any journal in the category that were cited during the JCR year;
and
- the Journal Impact Factor, which identifies the frequency with
which an average article from a journal is cited in a particular
year.
