About the h-index

 

The h-index was developed by J.E. Hirsch and is an index that attempts to measure both the productivity and impact of the published work of a scientist or scholar. In Scopus, the h-index is not a static value; it is calculated live on a set of results each time you look it up. The calculation was suggested by Hirsch and it can be summed up as follows:

"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."

Example An h-index for a group of selected documents or selected author(s) with an h-index of 12 means that out of the total number of documents selected to produce the graph, 12 of the documents have been cited at least 12 times. Published documents with fewer citations than h, in this case less then 12, are considered, but would not count in the h-index.

The same is true for the group of selected authors. If the author(s) have an h-index of 12, it means that out of the total number of documents produced by the author(s), 12 of the documents have been cited 12 times.
