H-Index in Scopus

Scopus now incorporates the h-index as a means to evaluate research performance, including unique graphs that enable users to interpret the value of the h-index by displaying publication and citation trends over time. The H-index is touted as being a objective measure of scientific research productivity.

How to get the H-Index in Scopus:

After performing an author search in Scopus, click on the "citation tracker" button to view the Citation Overview analysis, and then click on the h-graph button to view the graphical representation of the data.

Scopus only includes data for articles published from 1995 to the present. Thus the h-index data from Scopus is not complete for older researchers.

Read more about the "H-Index, from the Help file in Scopus:

The h-Graph displays the h index for a single author, multiple authors, or a group of selected documents. The h index is based on the highest number of papers included that have had at least the same number of citations. The h index was developed by J.E. Hirsch. Hirsch defines the h index 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."

For Example An h-graph 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.

For more information about the h index, see Hirsch, J.E. "An index to quantify an individual’s scientific research output." Department of Physics, University of California, San Diego.

The H-graph includes two lines: h index and the h-Line. The h index line represents the number citations received for each of the articles in descending order. The h-Line represents the number of citations equal to the number of articles.
