Описание метрик

h-index

Учёный имеет индекс h, если h из его N статей цитируются как минимум h раз каждая, в то время как оставшиеся (N - h) статей цитируются не более чем h раз каждая.

https://www.pnas.org/doi/full/10.1073/pnas.0507655102

i10-index

Число статей автора, получивших не менее 10 ссылок каждая.

https://scholar.googleblog.com/2011/11/google-scholar-citations-open-to-all.html

m-index

m-индекс ученого численно равен отношению его h-индекса к количеству лет, прошедших с момента первой публикации.

https://harzing.com/publications/white-papers/reflections-on-the-h-index

o-index

Среднее геометрическое h-индекса и числа цитирований наиболее цитируемой статьи ученого.

https://arxiv.org/abs/1511.01545

g-index

Для данного множества статей, отсортированного в порядке убывания количества цитирований, которые получили эти статьи, g-индекс это наибольшее число, такое что g самых цитируемых статей получили (суммарно) не менее g² цитирований.

https://doi.org/10.1007/s11192-006-0144-7

w-index

Если w статей ученого имеют не менее 10w цитирований каждая и другие статьи меньше, чем 10(w+1) цитирований, то w-индекс исследователя равен w.
