An Introduction to Community Detection in Multi-layered Social Network

Piotr Bródka, Tomasz Filipowski, Przemys┼éaw Kazienko
(Submitted on 26 Sep 2012)
Social communities extraction and their dynamics are one of the most important problems in today's social network analysis. During last few years, many researchers have proposed their own methods for group discovery in social networks. However, almost none of them have noticed that modern social networks are much more complex than few years ago. Due to vast amount of different data about various user activities available in IT systems, it is possible to distinguish the new class of social networks called multi-layered social network. For that reason, the new approach to community detection in the multi-layered social network, which utilizes multi-layered edge clustering coefficient is proposed in the paper.

Connect To Thrive

"Social connection improves physical health and psychological well-being. One telling study showed that lack of social connection is a greater detriment to health than obesity, smoking and high blood pressure. On the the flip side, strong social connection leads to a 50% increased chance of longevity.  Social connection strengthens our immune system (research by Steve Cole shows that genes impacted by social connection also code for immune function and inflammation), helps us recover from disease faster, and may evenlengthen our life. People who feel more connected to others have lower rates of anxiety and depression. Moreover, studies show they also have higher self-esteem, are more empathic to others, more trusting and cooperative and, as a consequence, others are more open to trusting and cooperating with them. Social connectedness therefore generates a positive feedback loop of social, emotional and physical well-being."

On the weakness of weak ties

On the weakness of weak ties | Human Behavior in networks | Scoop.it

Research Question:

Having all those definitions of ties we can now come up with a number of observations regarding the information diffusion between those people. The information diffusion is captured in the retweet network (see third layer in the schematic graphic) and the corresponding ties. In generall we want to look at how the different tie types affect the information diffused (retweets) between those people.

"Here’s a video of Alan Daly discussing his paper exploring social network analysis (SNA) and its potential to illuminate issues in school data use. This past summer I attended the LINKS Center for Social Network Analysis workshop, and it was a blast. I highly recommend it. The instructors and gaggles of TAs were all very talented and patient."

How People Interact in Evolving Online Affiliation Networks

How People Interact in Evolving Online Affiliation Networks | Human Behavior in networks | Scoop.it

The concept of social networks, in the age of Twitter and Facebook, seems like a really banal one. Social networks, however, have turned out to be a fertile ground for scientific studies of human interactions by not only social scientists, but also by physicists, from which we gain illuminating insights about ourselves and our societies. For example, why, and how, do we make new friends or establish fresh social ties? In this paper, we show that meaningful answers to these questions can be learned, by bringing concepts and methods from statistical physics to bear in a new analysis of the detailed growth dynamics of two networks associated with two online social-networking sites.
