A Review on Overlapping Community Detection Algorithms
نویسنده
چکیده
Community structure is an important feature of complex networks and social network communities refer to groups of individuals within which social interactions are intense and between which they are weak. Community detection algorithms answer a wide range of questions regarding the behavior and interaction patterns of people. Usually, communities in social network can overlap with each other. Detecting overlapping communities is very important to understand and analyze the structure of social network. Approaches to find overlapping nodes in complex networks are categorized based on group density, dynamic agents, fuzzy logic and local expansion and optimization. This paper reviews the characteristics and limitations of clique percolation techniques, fuzzy approach, label propagation algorithms and local expansion and optimization techniques.

The proposed algorithm in this research is based on the multi-agent particle swarm optimization as a collective intelligence due to the connection between several simple components which enables them to regulate their behavior and relationships with the rest of the group according to certain rules. As a result, self-organizing in collective activities can be seen. Community structure is crucial...
متن کاملDetecting Overlapping Communities in Social Networks using Deep Learning
In network analysis, a community is typically considered of as a group of nodes with a great density of edges among themselves and a low density of edges relative to other network parts. Detecting a community structure is important in any network analysis task, especially for revealing patterns between specified nodes. There is a variety of approaches presented in the literature for overlapping...
