Index h

The h index measures the impact of an author’s search by combining quality and quantity. 

  • All the works of an author are collected and arranged in descending order based on the citations received.
  • The index h is a measure of position, namely that in which the volume of citations is greater than or equal to the order number that the article occupies in a descending distribution of quotations.
The following example shows how the index h in this table is 4 (number of citations equal to or greater than its order number).
