Metrics and usage data


ORBi collects a variety of quantitative data for mapping the Institution's scientific production and outreach and to observe the deployment of Open Access.

It is important to use them in combination, taking into account the context and associating them with a qualitative assessment, as recommended by international initiatives like DORA (San Francisco Declaration on Research Assessment) and the Leiden Manifesto.

Citations of the publication

    • SCOPUS citations
      Number of citations of the article picked up by Scopus  (of which X without autocitations)

    • Dimensions Citations

Almetrics data

These are alternative measures aimed mainly at highlighting the use of scientific publications on the Internet, using, among other things, shares on social networks (Twitter, Facebook, LinkedIn ...), downloads on platforms such as Mendeley and mentions in blogs or wikis.

 

Indicators linked to the journal

  • Citescore (Scopus): ratio between the number of citations received by all the articles of the journal and the number of articles published by this journal. It is calculated for a 3-year publication period.
  • SJR (SCImago Journal Rank): measures the impact of a journal by taking into account the prestige of the citing journals (itself calculated on the basis of the number of citations they have received). It is the average number of citations of the journal's articles in the 3 years following its publication, each citation being weighted by the importance of the citing journal. It includes, to a limited extent, a journal's self-citations.
  • SNIP (Source Normalized Impact per Paper): measures the impact of a journal in its field. It relates the number of citations per paper in the journal to the total number of citations in the journal's field. 

Indicators linked to the author or to a group of publications

    • h-index or Hirsch Index

      This index attempts to measure both the scientific productivity and the apparent scientific impact of a scientist. According to Hirsh: "A scientist has index "h" if h of his/her papers have at least h citations each, and the other papers have no more than h citations each."

      In ORBi, the "h" index is based on the number of Scopus citations of the references listed in the report.
