Improved Impact Metrics for Most Atlantis Press Journals

June 24th, 2019

After the publication of Scopus' CiteScore metrics earlier this month and the release of Clarivate's 2019 Journal Citation Reports last week, Atlantis Press makes up the balance for its journals portfolio: most AP journals have recorded improved impact metrics.

Most notably, Atlantis Press' flagship journal the International Journal of Computational Intelligence Systems (IJCIS) achieved a 76% increase to its CiteScore from 1.89 for 2017 to 3.33 for 2018 and a solid 7.7% increase to its Impact Factor from 2.000 for 2017 to 2.153 for 2018. The IJCIS CiteScore performance now puts the journal in the top-10% of journals in the category "Computational Mathematics" and in the top-15% of journals in the category "General Computer Science". Besides the CiteScore, there were also strong improvements to other Scopus metrics: the journal's SNIP (Source Normalized Impact per Paper) increased from 0.823 for 2017 to 1.350 for 2018 and its SJR (SCImago Journal Rank) from 0.564 for 2017 to 0.719 for 2018.

A strong performance was also recorded for Atlantis Press' newly acquired journal the Journal of Epidemiology and Global Health (JEGH) which achieved a 56% increase to its CiteScore from 1.18 for 2017 to 1.84 for 2018. Other Scopus metrics for JEGH also improved: its SNIP (Source Normalized Impact per Paper) increased from 0.646 for 2017 to 1.178 for 2018 and its SJR (SCImago Journal Rank) from 0.566 for 2017 to 0.725 for 2018. Moreover, this journal which is currently in Clarivate's ESCI (Emerging Sources Citation Index) is due for evaluation for SCIE (Science Citation Index Expanded) later this year which may lead to it receiving an impact factor in 2020.

Mixed results were noted for the Journal of Nonlinear Mathematical Physics (JNMP) which saw a rather sharp decline in its Impact Factor from 1.438 for 2017 to 1.056 for 2018, while its CiteScore remained constant at 1.28. Also the International Journal of Networked and Distributed Computing (IJNDC) recorded a decline in its CiteScore from 0.45 for 2017 to 0.30 for 2018, with its SNIP (Source Normalized Impact per Paper) increasing by 14.7% to 0.273 and its SJR (SCImago Journal Rank) declining by 31.5% to 0.137.

Overall Zeger Karssen, Atlantis Press founder and publishing director, is pleased with the results: “In particular the Scopus metrics for IJCIS and JEGH are very impressive, but it is also good to see that the IJCIS Impact Factor has continued to increase for the 4th successive year and that the journal is showing good consolidation after a strong jump in 2017. There is also good news further down the line: we have an increasing number of journals indexed in ESCI and other high-quality databases such as Medline/PubMed now and these all have the potential to receive impact factors in due course. So our journals portfolio is improving in depth as well as breadth.
