20 years of network community detection

no code implementations30 Jul 2022 Santo Fortunato, M. E. J. Newman

A fundamental technical challenge in the analysis of network data is the automated discovery of communities - groups of nodes that are strongly connected or that share similar features or roles.

Robustness modularity in complex networks

1 code implementation5 Oct 2021 Filipi N. Silva, Aiiad Albeshri, Vijey Thayananthan, Wadee Alhalabi, Santo Fortunato

Here we propose a new measure based on the concept of robustness: modularity is the probability to find trivial partitions when the structure of the network is randomly perturbed.

Community Detection

Fast consensus clustering in complex networks

1 code implementation11 Feb 2019 Aditya Tandon, Aiiad Albeshri, Vijey Thayananthan, Wadee Alhalabi, Santo Fortunato

Algorithms for community detection are usually stochastic, leading to different partitions for different choices of random seeds.

Psychological and Personality Profiles of Political Extremists

no code implementations1 Apr 2017 Meysam Alizadeh, Ingmar Weber, Claudio Cioffi-Revilla, Santo Fortunato, Michael Macy

Global recruitment into radical Islamic movements has spurred renewed interest in the appeal of political extremism.

Community detection in networks: A user guide

18 code implementations30 Jul 2016 Santo Fortunato, Darko Hric

Community detection in networks is one of the most popular topics of modern network science.

Community Detection Misconceptions

Network structure, metadata and the prediction of missing nodes and annotations

1 code implementation1 Apr 2016 Darko Hric, Tiago P. Peixoto, Santo Fortunato

The empirical validation of community detection methods is often based on available annotations on the nodes that serve as putative indicators of the large-scale network structure.

Benchmark model to assess community structure in evolving networks

1 code implementation23 Jan 2015 Clara Granell, Richard K. Darst, Alex Arenas, Santo Fortunato, Sergio Gómez

In them, the time evolution consists of a periodic oscillation of the system's structure between configurations with built-in community structure.

Community detection in networks: Structural communities versus ground truth

no code implementations1 Jun 2014 Darko Hric, Richard K. Darst, Santo Fortunato

Algorithms to find communities in networks rely just on structural information and search for cohesive subsets of nodes.

Community Detection

Finding statistically significant communities in networks

1 code implementation10 Dec 2010 Andrea Lancichinetti, Filippo Radicchi, Jose' Javier Ramasco, Santo Fortunato

In this paper we present OSLOM (Order Statistics Local Optimization Method), the first method capable to detect clusters in networks accounting for edge directions, edge weights, overlapping communities, hierarchies and community dynamics.

Community detection in graphs

1 code implementation3 Jun 2009 Santo Fortunato

The modern science of networks has brought significant advances to our understanding of complex systems.

Benchmark graphs for testing community detection algorithms

1 code implementation30 May 2008 Andrea Lancichinetti, Santo Fortunato, Filippo Radicchi

Community structure is one of the most important features of real networks and reveals the internal organization of the nodes.

Scale-free network growth by ranking

1 code implementation3 Feb 2006 Santo Fortunato, Alessandro Flammini, Filippo Menczer

Network growth is currently explained through mechanisms that rely on node prestige measures, such as degree or fitness.
