The ASE/IEEE International Conference on Social Computing (SocialCom) will take place in Amsterdam (The Netherlands), September 3-6, 2012. The focus of SocialCom is on information and communication technologies aimed at modeling, analysis and synthesis of social interactions. The program will cover the whole spectrum of contexts where computers play a role in human-human and human-machine interaction, from co-located, face-to-face dyadic interactions up to large-scale on-line social networks.
