An Alphabet of Indexes
Bibliometric indices
A-index
- the average number of citations received by those publications in an author's Hirsch core
AR-index
- the square root of the sum of all age-weighted citation counts over all papers that contribute to the h-index
AWCR, AWCRpA and AW-index
- the number of citations to an entire body of work, adjusted for the age of each individual paper
c-index
- Measures the quality of papers by the distance between the author and anyone who cites his/her paper. The considered pool is a pool of citations, regardless of the paper to which those citations refer the quality function is given by the collaboration distance between the citing and the cited papers
g-index
- aims to improve on the h-index by giving more weight to highly-cited articles.
If you rank an authors articles by citation counts, the g-index is the (unique) largest number so that the top g articles received (together) at least g2 citations.
h-index
- A scientist has index h if h of his/her Np papers have at least h citations each, and the other (Np − h) papers have no more than h citations each
h2-index
- if the maximal n is n = 5 then at least 5 papers have attracted 25
citations each, or more, while fewer than 6 have attracted at least 36 citations each
hc-index (contemporary h-index)
- adds an age-related weighting to each cited article, giving less weight to older articles
hI-index
- divides the standard h-index by the average number of authors in the articles that contribute to the h-index, in order to reduce the effects of co-authorship
hI,norm
- first normalizes the number of citations for each paper by dividing the number of citations by the number of authors for that paper, then calculates hI,norm as the h-index of the normalized citation counts
hI,annual
- average annual increase in the individual h-index
hmindex
-uses fractional paper counts instead of reduced citation counts to account for shared
authorship of papers, and then determines the multi-authored hm index based on the resulting effective rank of the papers using undiluted citation counts.
m-index
- h/n, where n is the number of years since the first published paper of the researcher
s-index
- accounting for the non-entropic distribution of citations
