*** Extended deadline for submission 10 Oct 2008 ***

Web 2.0 (aka. social web) applications such as Wikipedia, LinkedIn and
FaceBook, are well-known for fast-growing online data production via
their network effects. Meanwhile, emerging Web 3.0 applications, driven
by semantic web technologies such as RDF, OWL and SPARQL, offer powerful
data organization, combination, and query capabilities.
The social web and the semantic web complement each other in the way
they approach content generation and organization. Social web
applications are fairly unsophisticated at preserving the semantics in
user-submitted content, typically limiting themselves user tagging and
basic metadata. Because of this, they have only limited ways for
consumers to find, customize, filter and reuse data. Semantic web
applications, on the other hand, feature sophisticated logic-backed data
handling technologies, but lack the kind of scalable authoring and
incentive systems found in successful social web applications. As a
result, semantic web applications are typically of limited scope and
impact. We envision a new generation of applications that combine the
strengths of these two approaches: the data flexibility and portability
of that is characteristic of the semantic web, and the scalability and
authorship advantages of the social web.

In this symposium, we are interested in bringing together the semantic
web community and the social web community to promote the collaborative
development and deployment of semantics in the World Wide Web context.
We welcome constructive papers on, for example: (i) how semantic
technologies, especially knowledge representation and collective
intelligence, can benefit social web content organization and retrieval;
(ii) how social web technologies can facilitate massive semantic content
production; and (iii) how to address the requirements, e.g., reasoning
scalability and semantic convergence issues, which emerge from the
combination.

We encourage submissions of full papers, extended abstracts,
demonstrations and posters describing research and applications that
deal with (but not limited to) the following topics on social semantic web:
* Collaborative and collective semantic data generation and publishing
* Semantic tagging and annotation for social web
* Data integration
* Data portability
* Data analysis and data mining
* Privacy, policy and access control
* Provenance, reputation and trust
* Scalable search, query and reasoning
* Semantically-enabled social applications: semantic wikis, semantic
desktops, semantic portals, semantic blogs, semantic calendars, semantic
email, semantic news, etc.

==Submission==
Interested participants should submit papers in PDF format to
http://www.easychair.org/conferences/?conf=ssw08. Submissions should be
formatted in the AAAI Format. Full papers are limited in 6 pages and
position papers/demos are limited in 2 pages. Selected papers from the
symposium will be published as an AAAI technical report.
