The Semantic Web is an extension of the current Web, aiming at enhanced search and navigation facilities and at integrating information from multiple sources. A question that is actively being discussed in conference panels, visionary papers, and project proposals is how the different approaches of Social Software and Semantic Web can be combined in a synergetic way.

CSSW will provide a podium for the rapidly emerging field of approaches that aim at exploiting Social Software concepts for the bootstrapping of the Semantic Web and lifting Social Software to the semantic collaboration level.

CSSW seeks to combining three different perspectives on the Social Semantic Web: the business and entrepreneurial perspective, which focuses on the added value of specific social semantic web applications; the technical perspective, which enables and supports the exploitation of the "ant intelligence" of social networks, and, last but not least, the social perspective, which explores motivations, benefits, and emergent effects. CSSW aspires to bring these three perspectives together, to widen existing horizons, to create novel ideas, and to find new ways of understanding this emerging field.
