Workshop on Ontologies in Peer-to-Peer Communities

Held as part of ESWC 2005
May 30, 2005
Heraklion, Greece

Deadline Extension

The deadline for the ESWC2005 Workshop on Ontologies in P2P Communities has been extended to March 24, 2005. Due to the many requests stemming from people being currently involved in project reviews and proposal writing we welcome also submissions of abstracts (1-2 pages) which can be expanded to full submissions until 15th of April 2005. See new "Important Dates" section below for details.


Recently, a lot of research has been aimed at bringing together and mutually augmenting the benefits of SemanticWeb technologies on the one hand and P2P systems on the other. Ontologies are a vital part of the SemanticWeb vision, providing machine-understandable, shared conceptualizations of the respective domains of interest within communities. Peer-to-peer (P2P) systems are a means for communities to establish communication among their members, foster collaboration and provide an infrastructure in which peers can share and create knowledge. The use of ontologies for and within P2P systems is expected be a crucial part of creating P2P communities that go beyond file-sharing. While most existing P2P systems are used for exchanging objects such as data files, which are described by few simple attributes such as a file name or a hash code, ontology-based P2P systems will open up new possibilities. They can enable richer, potentially more useful descriptions of peers, services, and shared artifacts, thus facilitating new ways of querying, sharing, and organizing knowledge within communities. The goal of the intended workshop is to bring together researchers and practitioners from the P2P, Semantic Web and Knowledge Management fields to present their work done within one or more of the topics of interest. We believe that at the present time, discussions about a common understanding of the area, models for distributed knowledge management systems, and novel ways of using, creating, and sharing ontologies in P2P communities are essential for the progress of the field.

Topics of Interest

Topics of interest include, but are not limited to:

  • Formation of P2P communities
  • Self-Description of peers
  • Trust and reputation in P2P communities
  • Social aspects of P2P communities
  • Distributed ontology engineering
  • Semantic routing
  • Query languages for semantic P2P systems
  • User interfaces and tools for distributed knowledge management
  • Semantic P2P applications


We invite two types of submissions for this workshop:
  • Technical papers (maximum 12 pages) in any of the topics of interest of the workshop (but not limited to them)
  • Short position papers (maximum 6 pages) in any of the topics of interest of the workshop (but not limited to them)
Submitted papers will be peer-reviewed and selected on the basis of these reviews. Accepted papers will be presented at the workshop. All submissions should be made electronically if possible, by email attachment and preferably in Postscript or PDF format.

All submissions must be sent to the workshop contact, Christoph Schmitz at . Although not required for the initial submission, we recommend to follow the format guidelines of ESWC (Springer LNCS -- LaTeX Style File), as this will be the required format for accepted papers.
