Motivation

Semantic Web technologies have reached a status where they influence our daily lives. On the one hand, applications for sharing semantically annotated pictures, blogs, and videos and semantic-enhanced social networking platforms are present. On the other hand, the so-called Web of Data with its thousands of billions of triples is leaving its research prototype status. Applications using Semantic Web technologies start to arise and to be used by a large number of users. However, although trust and privacy play a crucial role in its final development and adoption, in most of the running systems and research prototypes no or not sufficient solutions to address these topics are considered. The Semantic Web as well as the Social Web has reached a state where those issues have to be addressed seriously in order to become reality. As the Semantic Web goes mainstream, especially through its Social aspect, it is time for the community to gather around that topic.

SPOT09 is an ESWC 2009 workshop and will bring together, among others, researchers and developers from the field of Semantic Web, the Social Web, and trust and privacy enforcement. It provides the opportunity to discuss and analyze important requirements and open research issues for a trustful Semantic Web. We welcome both, theoretical and application oriented results, concerning how trust can be ensured in an open system like the Social Semantic Web as well as how Semantic Web technologies can be used or have to be extended in order to serve for privacy issues. We also plan to include a specific time slot for case studies and system demonstrations.

Topics of Interest

The list of topics that aims to be covered by the workshop include, but is not limited to:

Trust and Privacy on the Semantic Web, including

  • Ontologies for trust and privacy
  • Data provenance and trustworthiness of knowledge sources
  • Semantic web policies
  • Privacy by generalization of answers
  • Usage control and accountability
  • Trust-enabled linked data
  • Policy representation and reasoning

Trust and Privacy for Social Semantic Web Applications, including

  • Trust and privacy in social online communities (e.g., SIOC)
  • Privacy in Semantic Web sharing applications (e.g., semantic desktop)
  • User profiling and modeling vs. privacy
  • Privacy and community mining
  • Trust and reputation metrics
  • Usage mining and policy extraction
  • Privacy awareness in social communities
  • The Semantic Web as a trust enabler

Applications and Case Studies

  • Social Semantic Web case studies, prototypes, and experiences
  • Trust and privacy on social semantic platforms
  • Social network annoyance, social software fatigue, social spam
  • Managing information overload in the Social Web with privacy metrics
  • Trust and privacy for social software on mobile devices
  • Scalability of trust and privacy on the Semantic Web

Submissions

The following types of contributions are welcome:

  • Research Papers aims to explore how Semantic Web technologies can provide solutions to trust and privacy issues on the Web, focusing on one or more topics from the various ones identified within the main CFP. Especially, we very welcome papers focusing on theoretical work as well as applications regarding the benefits of Semantic Web technologies to solve these issues. Authors can submit short papers (up to 6 pages) as well as full papers (up to 12 pages) and will have the opportunity to present their work during the workshop. The papers should clearly define the motivation of the work with relevant scenarios and should also provide a clear overview and evaluation of the benefits of the proposed approaches.
  • Demos and Applications: participants have to submit a two-page paper containing a demo description together with a URI where the demo is available on-line. In addition, the demo should meet the following conditions:
    • It must utilize Semantic Web technologies (such as RDF, SPARQL, FOAF, SIOC, etc.).
    • It must deal with person or person-related data (profiles, trust, privacy, etc.)
    • Desirably in a social/community based platform (e.g,. dealing with Web 2.0 environments or social media platforms such as MySpace, Facebook)

Papers will have to be formatted using the Springer Publications format for Lecture Notes in Computer Science (LNCS). Submissions for the Research Papers and Demos and Applications will be made using the EasyChair Conference System, and proceedings of the papers will be provided through the CEUR online service.

Workshop Organization

The workshop will be co-located with the ESWC in Heraklion (Greece), and will be held on the 1st of June 2009. The workshop will consist of:

Opening session
This will permit introduction of the workshop topics, goals, participants, and expected outcomes.
Keynote
We plan to invite a keynote speaker with a strong industry back-ground. It is important to get both, real world challenges and impressions, as well as research visions regarding the topic. A discussion session following that opening keynote will be an opportunity for attendees to start discussions and it will foster the idea of an interactive event already from the beginning of the workshop.
Research Track
Full papers will be presented at the workshop in a 25 minutes session including a discussion. We may add small panel sessions at the end of each research session where the presenters are the panelists in order to foster discussion and comparisons about the papers presented.
Demo and Application Track
In order to stimulate discussions including practitioners and highlight future directions we plan to include a Demo and Application track.
Lightning Talks Track
We will provide a way for people to present feed- back on research track talks, as well as controversial topics potentially fostering discussions after the workshop. We envision short talks (three minutes maximum).
