Research Impact for Engineering

Journal Impact Factor

  • Journal Impact Factor is a tool provided by Journal Citation Reports that measures the average citation frequency of a journal's articles within a particular year.
  • Impact Factor is an indicator of journal impact that frequently serves as a proxy for individual article impact, though this practice has been subject to criticism (notably the San Francisco Declaration on Research Assessment).
  • Impact Factor calculation is based on a two-year period, where a journal's citations are divided by the number of total published citable articles.
  • See Journal Impact Factor | Journal Citation Reports video tutorial for more information about the factor itself and its retrieval in Journal Citation Reports database.

Scopus Journal Metrics

Alternative journal metrics tools are available in the Scopus database.

  • CiteScore is defined as "the number of citations received by a journal in one year to documents published in the three previous years, divided by the number of documents indexed in Scopus published in those same three years." 
  • SJR (SCImago Journal Rank) "is weighted by the prestige of a journal. Subject field, quality, and reputation of the journal have a direct effect on the value of a citation."
  • SNIP (Source Normalized Impact per Paper) "measures a source's contextual citation impact by weighting citations based on the total number of citations in a subject field. It helps you make a direct comparison of sources in different subject fields."
