This is an advanced course on the management and technological issues associated with new trends in social systems. The primary focus of the course will be on enterprise social systems that leverage social networks. Such social systems involve creating social spaces where people can collaborate online, get advice from trusted individuals and find goods/services through platform-mediated networks. This course will also emphasise the powerful role that social computing technologies (e.g., social networking sites, blogs, wikis, recommendation systems, social bookmarking, etc.) has played and a comprehensive set of business models for implementing these strategies.
