scientific quality index
The Scientific Quality Index (Pluskiewicz et al. 2019) is a slightly odd metric which is simply the sum of the mean citations per publication and the percent of publications with 10 or more citations (both adjusted for self- and co-author citations, in a perfect world). The authors considered it to be a slightly better judge of quality than metrics such as the h-index.
Example
Publications are ordered by number of non-self citations, from highest to lowest.
| Non-self Citations | 55 | 25 | 16 | 12 | 9 | 7 | 1 | 1 | 1 | 1 | 1 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Rank | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 |
Of the 18 publications, 4 have 10 or more non-self citations, 4/18 = 22.2%. The total non-self citations is 129, thus the mean non-self citations per publication is 7.2. The SQI is the sum of these values, or 29.4.
