Measuring Journal Impact
Journal Citation Reports
Journal Citation Reports provides ranking for journals in the areas of science, technology, and social sciences. For every journal covered, the following information is collected or calculated: Citation and article counts, Impact factor, Immediacy index, Cited half-life, citing half-life, Source data listing, Citing journal listing, Cited journal listing, Subject categories, Publisher information.
Scimago Journal Rank
“The SCImago Journal & Country Rank is a portal that includes the journals and country scientific indicators developed from the information contained in the Scopus® database (Elsevier B.V.).” Scopus contains more than 15,000 journals from over 4,000 international publishers as well as over 1000 open access journals. SCImago's "evaluation of scholarly journals is to assign weights to bibliographic citations based on the importance of the journals that issued them, so that citations issued by more important journals will be more valuable than those issued by less important ones." (SJR indicator)
Use this tool to find metrics that will be most relevant to your use case, filtering via broad discipline, research output, and impact type categories
Scopus Journal Analyzer
Use the Journal Analyzer to compare up to 10 Scopus sources on a variety of parameters: CiteScore, SJR (Scimago Journal and Country Rank), and SNIP (source normalised impact per paper)
Measuring Author Impact
H-Index is used by researchers to quantify research output by measuring author productivity and impact. This measure was developed by J.E. Hirsch and published in Proceedings of the National Academy of Sciences of the United States of America 102 (46): 16569-16572 November 15 2005. It reflects the productivity of authors based on their publication and citation records (Clarivate Analytics, 2019). The h-index is based on a list of publications ranked in descending order by the Times Cited. The value of h is equal to the number of papers (N) in the list that have N or more citations. This metric is useful because it discounts the disproportionate weight of highly cited papers or papers that have not yet been cited.
How do you calculate H-Index?
Your h-index is based on a list of your publications ranked in descending order by the Times Cited count. The value of h is equal to the number of papers (N) in the list that have N or more citations.
The researcher would have an h-index of 8, as 8 articles have been cited at least 8 or more times, and the remaining articles have each been cited 8 times or less.
TOOLS TO CALCULATE H-INDEX
Understanding Journal Impact Factor
While research metrics may seem well established in the scholarly landscape, it can be challenging to understand how they should be used and how they are calculated. The Metrics Toolkit is an online evidence-based resource for researchers, librarians, evaluators, and administrators in their work to demonstrate or assess the impact of research.(Champieux, 2018)
