Community Detection Survey

Introduction

The repository collects and refactors some overlapping Community detection algorithms. Major content is survey, algorithms' implementations, graph input benchmarks, submodules, scripts.

Recommend ide are from jetbrains, namely clion, pycharm and intellij for c++, python and java.

Some Non-Overlapping Community Detections Algorithms could be found in NonOverlappingCodes.

A community-detection survey in Survey, you can have a look, if interested.

Graph Benchmarks

Synthetic Tool

Content	Detail	Status
2009-LFR-Benchmark	LFR Benchmark to generate five types of graphs	build success, some files unused

Quality-Evaluation Metrics

Without-Ground-Truth

Evaluation Metric Name	Implementation	Heuristic
Link-Belonging-Based Modularity	link_belong_modularity.py	compare to random graph

With-Ground-Truth

Evaluation Metric Name	Implementation	Heuristic
Overlap-NMI	overlap_nmi.py	info-theory entropy-measure
Omega-Idx	omega_idx.py	unadjusted compared to expected

Algorithms

In each algorithm, there is a ReadMe.md, which gives brief introduction of corresponding information of the algorithm and current refactoring status. Category information are extracted, based on Xie's 2013 Survey paper Overlapping Community Detection in Networks: The State-of-the-Art and Comparative Study.

All c++ projects are built with cmake, java projects are built with maven, python projects are not specified how to build.

Presentation Files

survey-presentation-slides-yche.pdf is available.

Some files for my survey presentation is in Presentation, including algorithm visualization scripts, graph serialization related scripts and social network visualization scripts and corresponding figures.

Submodules(Dependencies)

Detailed information is in SubModules.

Submodule	Implementation Language	Detail
igraph	c	also provide python wrapper, graph utilities
matlab-bgl	c++, matlab	matlab implementation with bgl dependency
graclus	c++	graph partition algorithm
lcelib	c++	graph utilities by CxAalto

Scripts

Some file processing utility python scripts are put in Scripts.

Attention

These codes are all research codes, which I found through the internet. Please do not use them in production environment.
