Welcome to Zoo of Centralities
A continually updated encyclopedia of centrality measures in complex networks
Why Zoo of Centralities is needed?
The study of centrality has evolved rapidly. Over the years, scientists have introduced an enormous number of centrality metrics, creating a zoo of diverse and distinct approaches.
The vast number of centrality measures introduced over time has created several key challenges:
- Discoverability: many measures remain hard to find and unfamiliar to researchers.
- Accessibility: most measures lack available implementations, limiting their practical use.
- Redundancy: many models are often reinvented independently, causing duplication.
- Naming conflicts: without a unified classification, different measures sometimes share the same names (e.g. topological coefficient or local centrality), leading to confusion.
- Validation issues: new measures are often compared only to traditional metrics, ignoring more suitable or advanced options, which makes proper evaluation difficult.
CentralityZoo was created to overcome these obstacles by organizing this complex landscape, offering clear information, and enabling researchers to access and apply a broad range of centrality measures with ease.
