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

From: Feature-enriched author ranking in incomplete networks

  Feature Initialisation: R(Ai) Description
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.
  1. OTARIOS considers both the authors’ productivity and the direct influence of outsiders on the authors. We create different variants of these criteria, e.g., PV+V uses volume (P) and venue prestige (V) to measure author productivity, and uses venue prestige (V) to measure the direct influence of outsiders
