  Social Networks and Web 2.0

Today a second generation of web-based communities and hosted services - 
such as social networking sites, wikis and folksonomies - is emerging 
which facilitate collaboration and sharing between users. The term Web 
2.0 has been coined to embrace all those new collaborative applications 
and also to indicate a new "social" approach to generating and 
distributing Web content, characterized by open communication, 
decentralization of authority, and freedom to share and re-use. Implicit 
and explicit in many Web 2.0 applications are social networks, through 
which users share and filter content, collaborate, seek information, and 
interact socially on the Web.

The Web 2.0 and Social Network Track provides a unique forum both for 
describing innovative collaborative and open applications, and data 
sharing scenarios, as well as novel technologies and methodologies for 
building and managing these applications. We welcome contributions 
relating to specific classes of applications as well as to cross-cutting 
issues. Relevant topics include, but are not restricted to, the following:

       E-Communities and Web-based collaboration
       Ethnographic and data mining analysis of online communities 
including blogs, online social networking and social media sites, and 
tagging systems
       Temporal and community evolution of Wikipedia and other open 
collaborative efforts
       Social network analysis of online environments, including 
community discovery and structure
       Social reputation and recommendation systems, trust management
       Collaborative filtering and content ranking using social media
       Data management in collaborative open applications
       Assured data sharing and integration of access control policies
