Social computing is concerned with the intersection of social behaviour and computing systems, creating or recreating social conventions and social contexts through the use of software and technology. Various social computing applications such as blogs, email, instant messaging, social networking (Facebook, MySpace, Twitter, LinkedIn, etc.), wikis, and social bookmarking have been widely popularised where people interact socially via computing space. Such applications have been profoundly impacting social behaviour and life style of human beings while pushing the boundary of computing technology simultaneously. While people can enjoy or even indulge in the benefits such as freedom and convenience brought about by social computing, various key issues such as privacy protection, touch-screen based arty HCI design, and modelling of social behaviour in computing space still remain challenging.

SCA (Social Computing and its Applications) is created to provide a prime international forum for both researchers, industry practitioners and environment experts to exchange the latest fundamental advances in the state of the art and practice of Social Computing and broadly related areas.
