Second ACM Workshop on Social Network Systems
March 31, 2009
University of Erlangen-Nuremberg
Nuremberg, Germany
(Co-located with EuroSys 2009)

The Second Workshop on Social Network Systems (SNS'08) will gather researchers to discuss novel ideas about computer systems and social networks.

Online social networks are among the most popular sites on the Web and continue to grow rapidly. They provide mechanisms to establish identities, share information, and create relationships. The resulting social graph provides a basis for communicating and distributing and locating content.

Broadly, the systems issues of social networks include:

* How can systems infrastructure be improved for social networks? Infrastructure includes database systems, operating systems, file systems, and storage systems.
* How can the social graph be leveraged in computer system design? The social graph encodes trust and common interests. How and to what extent can this encoding be used to improve computer systems?
* How can social networks be modeled and characterized? What has been learned from the operation of existing systems?

Topics of interest include, but are not limited to:

* Security and privacy.
* Leveraging the social graph in systems design.
* Real-time monitoring and query processing.
* Database issues for offline analysis.
* Experiences with deployed systems.
* Crawlers and other mechanisms for observing social network structure.
* Measurement and analysis, including comparative analysis.
* Tools for designing and deploying social networks.
* Network dynamics, including relationships between network links and user behavior.
* Benchmarks, modeling, and characterization.
* Decentralization: methods for integrating multiple networks.
* Application programming interfaces (APIs) for social networks.

The papers presented, as well as a summary of the discussion, will be archived electronically. Accepted papers may be subsequently revised, expanded, and submitted to full conferences and journals.

Submitting a Paper
Papers must be received by 23:59 GMT, on February 2, 2009. This is a hard deadline. Submissions should contain six or fewer two-column pages, including all figures and references, using 10-point fonts, standard spacing, and 1-inch margins (we recommend the ACM sig-alternate template, LaTeX template available here). Please number pages. All submissions will be electronic, and must be in either PDF format (preferred) or PostScript. Author names and affiliations should appear on the title page. Reviewing will be single-blind.

This workshop is sponsored by ACM, ACM SigOps, and EuroSys.
