Viable online communities

Overview
One of the major issues facing socially-driven content and collaborative work on the Web (such as
Wikipedia) is the lack of tools to measure at large scale the evolution of content (in terms of quality and quantity), to reduce the drop-out rate of active contributors or to detect vandalism in a timely manner. Collaborative projects typically die of inactivity for an insufficient number of valuable contributions or, conversely, whenever quality assessment becomes unmanageable due to content explosion or inappropriate measures against spam or vandalism. Governance of wiki-based communities has been based so far on a shared corpus of best practices and recommendations, due to the lack of tools to identify virtuous or potentially disruptive patterns in a timely and measurable way.
Can we identify factors that determine the
life and death of content-based online communities? How can communities in mutual competition secure their performance and the quality of their output? What is the relation between governance, content selectivity and growth of online communities?
The aim of this project is to study factors affecting the sustainability of content-based online communities and help develop policies to achieve or restore desired targets in content and population dynamics. Case studies for this project include content-based social networking services like
Flickr and
wiki-based communities.
