An insight into properties of real world networks

Online social networks have been evolving at a rate much greater than expected. One of the prominent features of social networks is the evolution of communities which can be characterized as a group of people who share a common relationship or tie among themselves. As the penetration of social network is increasing in our lives, so is the interest of researchers in this field. Earlier studies on social network analysis mainly focused on static network structures rather than dynamic processes, however with the passage of time, the networks have also evolved and the researchers have started to focus on the aspect of studying dynamic behavior of networks. The paper discusses the main elements in social network analysis from network perspective to community detection and presents experimental results of analysis of our Facebook network.
