Bibliometrics & Open Metrics

Bibliometrics 'measures' scientific publications using quantitative methods. You can use bibliometric analysis as evaluation tool or as research tool.

Frequent Bibliometric Indicators

Citation frequency Indicates how often a publication has been cited in other scientific publications.
Impact factor Indicates how often articles of a journal are cited on average (see specifications in Wikipedia).
h-Index Value indicates the number X publications of a person that have been cited at least X times (see specifications in Wikipedia).
Altmetrics Metrics based on machine evaluation of modern forms of communication in relation to individual articles (consult altmetrics).


Benefits and Limitations of Bibliometrics

Bibliometric measurements alone are not sufficient to assess the importance of a research output - they cannot replace qualitative assessments. Nevertheless, bibliometric indicators help you to better assess and compare the visibility of your research.

In addition, you can use the data when researching a wide range of questions, such as: 

  • Which journal is suitable for publication of my paper?  
  • How do I substantiate my scientific achievement?
  • What are the thematic trends in my field?
  • Who is doing research in my field, where can I find cooperation partners?
