Research Impact is the influence of a scholar's work on academia as well as the wider world.
Adapted from "Pathways to Impact" Research Councils UK.
Research Impact can help support:
The journal impact factor measures the frequency with which an 'average article' in a journal has been cited in a particular year or time period.
The h-index measures an author's productivity (number of publications) and citation impact (number of citations received).
The g-index is an index for quantifying scientific productivity based on publication record (an author-level metric). It was suggested in 2006 by Leo Egghe. See Harzig's Publish or Perish Manual.
The i10-index is a measure used only be Google Scholar that shows the number of publications with at least 10 citations.
The Eigenfactor score ranks a journal's influence or prestige by looking at the number of times articles published in a journal over the past 5 years have been cited in the Journal Citation Reports (JCR). Citations from more influential journals are weighted more than citations from less influential journals.
Altmetrics are non-traditional measures of citation impact. They are based on online activity from many web services such as: PubMed, Mendeley, Facebook, Twitter, research blogs and other sources. They show how often an article has been viewed, downloaded or shared via various social media outlets.
