What are author metrics?
- Author metrics are measures that determine the impact of an author’s research.
What is the h-index?
- The h-index of a researcher is the highest number of publications with at least that number of citations
- For example: a researcher has an h-index of seven if he/she has seven publications with at least seven citations
Measures both the productivity and the impact of a researcher
What are the benefits of the h-index?
- It is not affected by a single highly-cited publication
- It is calculated by citations to an article, not to the journal it is published in, which is a more accurate representation of the author’s impact
- It can be used to calculate impact of groups of researchers, departments, and institutions
- Available on Web of Science, Google Scholar
What are the limitation of the h-index?
- Limited by total # publications, so it’s not as beneficial to early-career researchers, and publishing pace varies between disciplines
- No inclusion of informal mentions (ex. Social media, news, blogs)
What is Egghe’s g-index?
- Puts more weight on highly cited papers
- Not as widely accepted as h-index
