With half a billion active users, online social networks (OSN) have attained critical mass and triggered intense research interest in collaborative systems and the analysis of the structure and properties of online communities.

WOSN will bring together researchers and practitioners to discuss the challenges and important questions posed by emerging online social applications. Of particular interest are problems related to network and system architecture design that can best support emerging and future social and collaborative systems, and how those social networks can shape the design of existing distributed systems and real networks. The goal of the workshop is to facilitate cross-disciplinary discussion of relevance to computer networking, involving novel ideas and applications, and experimental results.

The workshop solicits original, previously unpublished ideas on completed work, position papers, and/or work-in-progress papers. We encourage papers that propose new research directions or could generate lively debate at the workshop.
Topics

Topics of interest include, but are not limited to the following:

* Implications of social networking on network and distributed systems design
* System design for social networks
* Network architecture design to support large scale social applications
* Search strategies in social networks
* Rating, review, reputation, and trust systems
* Recommendation / collaborative filtering systems
* Expertise / interest tracking
* Anonymity and privacy
* Measurement and analysis of online communities
* Social media analysis: blogs and friendship networks
* Mobile social networks
* Information sharing and forwarding
* Decentralized (ad hoc) network applications and services
* Challenges posed by social networks
