More than ever, the Semantic Web is becoming reality as it is an integrated component of the Web we are browsing everyday - be it the Open Linked Data movement that nowadays exposes over 10 billion triples of RDF or the annotated and structured information available on Web pages used by major search engines, such as Yahoo! SearchMonkey and Google. Moreover, social data about people and their interaction is made available in machine-understandable format in projects like FOAF or SIOC. Facing this amount of data, privacy and trust consideration is an important step to take right now. The challenging research questions arising from this movement include:

We expect discussions and results concerning questions like these at SPOT2010 leading to solutions and research results in the realm of Semantic Web and social data for the pervasive issue of privacy and trust on the Web.

Topics of Interest

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

Semantic Technologies for Trust and Privacy on the Web

  • Privacy by generalization of answers
  • Ontologies for trust and privacy
  • Semantic Web policies
  • Usage control and accountability
  • Policy representation and reasoning
  • Semantic Web technologies for access control
  • Trusted Knowledge Representation and Reasoning on the Semantic Web

Data provenance and trustworthiness of knowledge sources

  • Trust-enabled linked data
  • Ontology hijacking
  • Scalability of trust and privacy on the Semantic Web

Trust and Privacy for Social Applications

  • 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
  • Social Network annoyance, social software fatigue, social spam
  • Managing information overload on the Social Web with privacy metrics
  • Trust and privacy for social software on mobile devices


Please submit your work at SPOT's easychair page.

The following types of contributions are welcome:

  • Research Papers: short (up to 6 pages) and full (up to 12 pages) technical papers that 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. 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 (such as profiles, buddylists, reviews, comments, etc.)
    • Additionally, the demo may operate in a social media platform, such as MySpace, Facebook, netvibes, iGoogle, etc.

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.

Important dates

Last chance submissions for demos and short papers:
May 23, 2010 (23:59 pm Hawaii time, GMT-10) (to be presented at the workshop but not part of the proceedings)
Submission deadline for full, short, and demo papers:
March 7, 2010 March 14, 2010 (23:59 pm Hawaii time, GMT-10)
Notification of acceptance for full papers:
April 16, 2010
Camera-ready paper submission for full papers:
April 23, 2010
May 31, 2010

Workshop Organization

The workshop will be co-located with the ESWC in Heraklion (Greece), and will be held on the 30th or 31st of May 2010. The workshop will consist of:

Opening session
This will permit introduction of the workshop topics, goals, participants, and expected outcomes.
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).
