Journal Impact Factor (and other scientometric indicators)

Back to overview
 

The Journal Impact Factor (JIF), determined by Clarivate Analytics, is currently the most established and widely used scientometric/bibliometric indicator at journal level.

The JIF of a journal is the average number of citations received in a given year by articles published in that journal during the two preceding years. The greater the value, the more influential the journal. However, the value range differs greatly depending on the field of research.

The previous year’s results are published annually (around the middle of the year) in the Journal Citation Reports.

10 of our journals are currently listed in the Clarivate Analytics Journal Citation Reports and received an Impact Factor for 2017.

The following journals are newly included in the Journal Citation Reports:

  • Reviews on Environmental Health (1,284)
  • Semiotica (0,183)

72 of the indexed titles have increased their Impact Factor compared to last year. 36 Impact Factors decreased.

Journals for which the Impact Factor value grew exceptionally:

  • Advances in Nonlinear Analysis: from 2,844 to 4,674
  • Applied Linguistics Review: from 0,351 to 1,286
  • Nanophotonics: from 4,492 to 6,014
  • Pure and Applied Chemistry: from 2,626 to 5,294
  • Reviews in Inorganic Chemistry: from 1,200 to 2,421
  • Reviews in Mineralogy & Geochemistry: from 3,913 to 8,846
  • Theoretical Linguistics: from 0,864 to 2,000

Journals which have exceptionally high ranks:

  • Advances in Nonlinear Analysis: rank 3/309 in Mathematics and 2/252 in Applied Mathematics
  • Clinical Chemistry and Laboratory Medicine: rank 7/30 in Medical Laboratory Technology
  • Cognitive Linguistics: rank 23/181 in Linguistics
  • Theoretical Linguistics: rank 18/181 in Linguistics
  • Fractional Calculus and Applied Analysis: rank 7/309 in Mathematics, 10/252 in Applied Mathematics and 11/103 in Mathematics, Interdisciplinary Applications
  • Holzforschung: rank 16/66 in Forestry and 2/21 in Materials Science, Paper & Wood
  • Nanophotonics: rank 19/146 in Applied Physics, 41/285 in Materials Science, Multidisciplinary, 23/92 in Nanoscience & Nanotechnology and 8/94 in Optics
  • Journal für die reine und angewandte Mathematik (Crelle's Journal): rank 20/309 in Mathematics
  • Reviews in Chemical Engineering: rank 18/137 in Chemical Engineering
  • Reviews in Mineralogy & Geochemistry: rank 3/85 in Geochemistry & Geophysics and 1/29 in Mineralogy

CiteScore, SCImago Journal Ranking and Source Normalized Impact per Paper are three further well-established scientometric indicators on journal level. They are based on the Scopus data. Each summer, the figures for the previous year are released.

CiteScore measures like the Journal Impact Factor average citations received per document published in a specific journal. Instead of a two-year window CiteScore uses a three-year window.

SCImago Journal Ranking (SJR) accounts for both the number of citations received by a journal and the importance of the journals where such citations come from. SJR computation uses an algorithm similar to Google PageRank.

Source Normalized Impact per Paper (SNIP) measures contextual citation impact by weighting citations based on the total number of citations in a subject field. SNIP is defined as the ratio of a journal's citation count per paper and the citation potential in its subject field. It aims to allow direct comparison of sources in different subject fields.
