The Fifth International Conference on Computational Aspects of Social Networks (CASoN) organized in Fargo, USA brings together an interdisciplinary venue for social scientists, mathematicians, computer scientists, engineers, computer users, and students to exchange and share their experiences, new ideas, and research results about all aspects (theory, applications and tools) of intelligent methods applied to Social Network, and to discuss the practical challenges encountered and the solutions adopted. Industrial Workshop/Tutorials and conference sessions will allow individuals interested in the theory, methods, or applications of social network analysis to share ideas and explore common interests. The conference is expected to provide an opportunity for the researchers to meet and discuss the latest solutions, scientific results and methods in solving intriguing problems in the fields of Social Networks. The conference programme will include workshops, special sessions and tutorials, along with prominent keynote speakers and regular paper presentations in parallel tracks. Like in previous years, all accepted and registered papers are expected to be included the conference proceedings and will be submitted for indexing in IEEE Xplore. The General Chairs, along with the entire team cordially invite you to submit your latest research results and to take part in the upcoming conference, to be held during August 12-14, 2013 in Fargo, USA.
