contemporary h-index

The contemporary h-index (Sidiropoulos et al. 2007) is designed to give more weight to the citations of recent publications and less weight to the citations of older publications. In its most general form, the contemporary score for a specific publication is

$$S^C_i=\gamma \left(Y-Y_i+1\right)^{-\delta}C_i.$$

The contemporary h-index for an author, hC, is calculated similarly to the standard h-index, in that an author has a score of hC if hC of their articles (ranked by SC) have SChC.

$$h^C=\underset{i}{\max}\left(i \leq S^C_i\right)$$Sidiropuolos et al. (2007) set γ = 4 and δ = 1. These choices have the consequence of making this metric virtually identical to the hpd-index, except measured on a four year cycle rather than a decade.

Example

Publications are ordered by adjusted number of citations, from highest to lowest.

The largest rank where \(i \leq S^{C}_i\) is 6.
