A new model for communities' detection in dynamic social networks inspired from human families

Abstract

Nowadays, social networks have been widely used by different people for different purposes in the world. The discovering of communities is a widespread subject in the space of social networks analysis. Many interesting solutions have been proposed in the literature. However, most solutions have common problems: the stability and the community structures quality. In this paper, we propose a new model to find communities based on a new concept called 'large families'. This model will be used, to motivate a community detection strategy to identify and effectively monitor the evolution of dynamic communities. We propose a compromise between the stability and the quality metrics. We apply our model on a real social network of the karate club of Zachary. Also, we describe experiences of our model on a large scale network of Enron's email data set as broader Benchmark Network. Simulations results show that our proposed model is globally satisfactory.

P2PCF: A collaborative filtering based recommender system for peer to peer social networks

“…This definition was extended to include "any recommender system that targets social media domains" [26]. The new definition covers systems recommending any objects in social media domains such as items, tags, links, people, and communities [17,57]. It has been shown that social considerations improve recommender systems since there is a significant overlap between users' interest and connections [48,56,61].…”

Application Layer Multicast Based Services on Hierarchical Peer to Peer Architecture

“…NICE [9] uses hierarchical clustering techniques to build overlay tree, whereby group members arrange themselves into clusters with the neighboring nodes. Recent type of ALM based applications have been emerged the P2P networking such as streaming [14], telemedecine [15] and social networking [16]. The main objective of our proposed model is to build an efficient and optimized multicast tree from any node (root or sender) to all other nodes (receivers) using HPM as underlying architecture.…”
