Impact factor

Description

Impact factor is a measure of a scientific journal's citations per publication. The Journal Citation Reports, maintained by Clarivate Analytics, provides the calculated impact factors. The IF is frequently used as an indicator of a journal's importance or prestige, which is nowadays increasingly contested.

Journal Citation Reports - Clarivate Analytics

Clarivate Analytics (former part of Thomson Reuters) maintains the Journal Citation Reports, which is used as the basis to define a journal impact factor.
The impact factors in a given year are calculated as the ratio between the number of citations in that year for publications that were published in the two previous years.
Journal Citation Reports journal profiles aggregate publication and citation data sourced from the Web of Science Core Collection. To enter the Web of Science, journals that meet the quality criteria but not yet the impact criteria enter the Emerging Sources Citation Indexβ„’ (ESCI), then ESCI journals that gain impact move to Science Citation Index Expandedβ„’ (SCIE), part of the β€œWeb of Science Core Collection”.

DOAJ does not approve of the use of Impact Factors. However, DOAJ acknowledges that the only official Impact Factor is that created by Clarivate. Journals must not display Impact Factors/similar rankings from any other service when included in DOAJ.

DORA

DORAs recommendations on the use of impact factors:
  • The need to eliminate the use of journal-based metrics, such as Journal Impact Factors, in funding, appointment, and promotion considerations;
  • The need to assess research on its own merits rather than on the basis of the journal in which the research is published; and
  • The need to capitalize on the opportunities provided by online publication (such as relaxing unnecessary limits on the number of words, figures, and references in articles, and exploring new indicators of significance and impact).
