Calcolatore Fattore di Impatto Citazioni — Formula

How the H-Index Works

A researcher has an h-index of h if h of their papers have each been cited at least h times.

Estimation

An approximate h-index can be estimated as:

h ≈ floor(sqrt(Total Citations))

This approximation (Hirsch's original heuristic) works well for typical citation distributions. The exact h-index requires sorting papers by citation count.

Context

  • Early career: h = 5-10
  • Mid career: h = 15-30
  • Senior researcher: h = 30-60
  • Field leaders: h = 60+

    • Esempio Risolto

    A researcher has 50 publications with 800 total citations.

    1. Average citations: 800 / 50 = 16.0 per paper
    2. H-index estimate: floor(sqrt(800)) = floor(28.3) = 28
