              *******CALL FOR PAPERS*******
                     1st Workshop on
       Semantics in Peer-to-Peer and Grid Computing
                          at the
     Twelfth International World Wide Web Conference
              20 May 2003, Budapest, Hungary
                 in cooperation with the
        GGF Semantic Grid Research Group (SEM-GRD)
    Workshop URL: http://www.isi.edu/~stefan/SemPGRID

Topics and Content

The Semantic Web is widely accepted as a means to enhance the Web with machine processable content. However, mostly the Semantic Web is aiming at techniques and technologies for static information, in contrast to dynamic services or distributed computing. Several interest groups and efforts are working on infrastructure for enabling distributed computing. The organization of these efforts are in part top down organized efforts, involving multiple formal organizations and dedicated projects, and bottom-up efforts, sometimes started by single organizations or individuals in a grassroots effort.

The Grid is aiming at technologies which allow the flexible, secure, coordinated resource sharing among dynamic collections of individuals, institutions, and resources, enabling virtual organizations. Problems encountered include authentication, authorization, resource access, resource discovery, and interoperation of active services. The same problems are eminent in the Peer-to-Peer (P2P) area, where projects are typically organized in a bottom-up fashion. Reusable infrastructures like SUN's JXTA are emerging, attracting numerous application based on of this infrastructures appear. However, each application uses its own data format, and it is hard to see how applications interoperate.

A related area is Web Services: driven by industry efforts numerous specifications are developed, which are of interest for the Grid projects as well as for the for the Peer-to-Peer efforts. Although there is an agreement that Web Services would benefit from more semantics, little systematic research has been done on the problem of how to combine the notions of Web Services with the results of the Semantic Web, Peer-to-Peer and Grid computing.

Topics of interest for technical papers include, but are not limited to the following: * Scalable infrastructures for service discovery in Grid computing and P2P networks, e.g., based on reconfiguration of the network with respect to shared interests or shared ontologies * Interoperation infrastructure for enabling heterogeneous peers to exchange and translate information * Emergent Semantics and incrementally learning and evolution of ontologies in an P2P environment * Metadata infrastructures for P2P and Grid computing * Task ontologies and service composition languages * Semantics-based routing * Semantics-based topologies for P2P networks * Agent-Architectures based on P2P and Grid Computing technology

The workshop will be organized in part around talks presenting research results in the intersection of the Semantic Web, P2P and Grid computing. Another important part of the workshop will be break-out groups, focusing on the amalgamation of Semantic Web and distributed computing. We hope the break-out groups will evolve into independent working groups and generate follow-up activities, which contribute to the technology areas. The proceedings will be published on the Web and a workshop report will summarize the outcome of the break out groups.
