Table 3 List of features used for OTARIOS’ author rank initialisation: R(A_i)

Productivity

Volume (P)

\(\frac {\sum \limits _{(P_{j} \in \mathcal {P}_{A_{i}})}\frac {1}{|\mathcal {A}_{P_{j}}|}}{\sum \limits _{(A_{i'} \in \mathcal {A})}\sum \limits _{(P_{j} \in \mathcal {P}_{A_{i'}})}\frac {1}{|\mathcal {A}_{P_{j}}|}}\)

Favours publishing many papers with few co-authors.

Recency (A)

\(e^{\frac {-\delta (A_{i})}{\tau }}\)

Favours publishing recently.

Venues (V)

\(\Big (\sum \limits _{(P_{j} \in \mathcal {P}_{A_{i}})}v(P_{j})\Big) \times |\mathcal {P}_{A_{i}}|^{-1}\)

Favours publishing in prestigious venues.

Outsiders Influence

Individuality (W)

\(\sum \limits _{(A_{i'} \rightarrow A_{i}, P_{j})}\frac {\lambda (A_{i'}) \times w(A_{i'}\rightarrow A_{i},P_{j})}{w_{out}(A_{i'})}, A_{i'} \in \mathcal {O}\)

Favours being cited by outsiders that cite few authors.

Recency (A)

\(\sum \limits _{(A_{i'} \rightarrow A_{i}, P_{j})}\frac {\lambda (A_{i'}) \times a(A_{i'}\rightarrow A_{i},P_{j})}{a_{out}(A_{i'})}, A_{i'} \in \mathcal {O}\)

Favours being cited by outsiders more recently.

Venues (V)

\(\sum \limits _{(A_{i'} \rightarrow A_{i}, P_{j})}\frac {\lambda (A_{i'}) \times v(A_{i'}\rightarrow A_{i},P_{j})}{v_{out}(A_{i'})}, A_{i'} \in \mathcal {O}\)

Favours being cited by outsiders in prestigious venues.
