Measuring Research Impact: Home

Metrics Methods and Evaluation

Uses of evaluation

  • Publication activities of universities as a funding criterion (Ministry of Education 2015-)
  • Research evaluation and management
  • Benchmarking
  • University rankings and institutional publication activity
  • Recruitments

The impact of scientific publications

What can be measured?

  • Publications: per year, per author
  • Number of citations: per publication, per author, per journal
  • Publication type: articles, conference papers, dissertations, monographs, reports
  • Collaboration: between researchers, groups, organizations, countries

Differences between disciplines

Different disciplines have markedly different publishing and citing patterns. These include:

  • Publication types (e.g. articles vs. monographs)
  • Choice of language; international nature of the scientific communication differs
  • Publishing process (length, frequency, delay)
  • Co-authoring and order of authors
  • The ageing speed of publications
  • Degree of popularization
  • Citation practices (the numbers and attention expectancies vary)


  • Research impact measures are not comparable across disciplines.
  • Quantitative methods (metrics) have to be adapted to suit the discipline in question
