WORKSHOPS
Despite often working on similar topics and goals, the artificial
intelligence and agent communities have been somewhat separate from those of databases and
information systems. This lack of interaction causes members of one community to be
unaware of the problems, results, trials, and errors that originated in the others.
Indeed, e-service development draws on research and technology from all of these research
communities. A key objective of this workshop is to provide a forum that fosters
collaboration and synergies among all e-service researchers. The workshop will expose
systems-oriented e-services researchers to the approaches and technologies being developed
by the Semantic Web e-services community, and will likewise expose Semantic Web e-services
researchers to the full breadth of systems issues raised by e-services, thereby enabling
researchers to leverage ideas and results coming from research groups that have
heterogeneous backgrounds but common goals. This multidisciplinary nature of the workshop
is also reflected in the composition of the organizing and program committee, that include
members of all the communities mentioned above.
Specifically, the "E-Services and the Semantic Web" workshop
will provide a forum for presentation and discussion of theoretical foundations,
computational techniques, and emerging systems technologies for e-service description,
discovery, and composition. This will include investigation of e-services issues in:
- the application of the Semantic Web paradigm to e-services
- workflow and distributed systems (e.g., process models for e-services,
transactional properties, security, optimization)
- AI (e.g., knowledge representation and reasoning, ontologies, planning, and
verification)
- databases (e.g., metadata, data management)
The workshop will also address principled applications of these
technologies in areas such as e-commerce, e-business, health care, scientific computing,
education, and e-government.

The World Wide Web has become part of our everyday life and information
retrieval and data mining on the web is now of enormous practical interest. Some of the
algorithms supporting these activities are based substantially on viewing the web as a
graph, induced in various ways by links among pages, links among hosts, or other similar
networks.
The aim of the 2003 Workshop on Algorithms for the Web-Graph (WAW 2003) is
to further the understanding of these web-induced graphs, and stimulate the development of
high-performance algorithms and applications that use the graph structure of the web.
Topics of interest include but are not limited to:
- Mathematical and physical models for the web
- Algorithms for analyzing the web graph
- Modification of classic graph algorithms to bring them to web scale
- Representation and compression of the web graph
- Topology generators
- Graph oriented statistical sampling of the web
- Practical algorithmic techniques
- Application of web graph algorithms to information retrieval on the
web, data mining, etc.
- Crawling as a graph search process
- Empirical studies and issues
Many contributed papers presented in past editions of WWW belong to some
of these topics and therefore we expect this workshop to be of interest to a fair number
of WWW attendees.

The Semantic Web is widely accepted as a means to enhance the Web with
machine processable content. Several workshops dealt with the development of techniques
and technologies for representing and using information with formally specified semantics
on the Web. However, mostly the Semantic Web is aiming at techniques and technologies for static
information, in contrast to dynamic services or distributed computing,
which is the topic of several interest groups, which are working on infrastructure for
enabling distributed computing. 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, a top-down effort, 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 applications based once these infrastructures
appear. However, each application uses its own data format, and it is hard to see how
applications should 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 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 notion the Semantic Web with Web Services, Peer-to-Peer and Grid
computing.
The main topic of this workshop will be the relationship between Semantic
Web, Grid computing and Peer-to-Peer efforts, and how developed technologies in one area
can advance another area. More specifically, workshop topics include:
- 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
- Incrementally learning and evolution of ontologies in a distributed
computing environment.
- Metadata infrastructures for P2P and Grid computing
- Task ontologies and service composition languages
- How can Semantic Web services benefit from being Grid Services.
The workshop will be organized in part around talks presenting research
result 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.

Community Informatics is the study of information and communications
technology to support communities and their processes. This includes achieving community
objectives, such as overcoming "digital divides", and supporting community-based
IT/ICT-enabled initiatives in community economic development, health, environmental and
sustainable development, community-focused learning and civic engagement and social
justice. Community Informatics traditionally has been applied to "local"
communities in a particular local geographical area. Virtual communities are concerned
with creating and sustaining on-line "communities of interest", gaming
communities, among others. Communities of Practice are virtual communities focusing on
sharing knowledge among peers within organizations. Virtual communities, by definition,
depend on technology, but often only use limited tool sets to support specific types of
interaction.
(Virtual) Community Informatics lies at two cross-roads: (a) bringing
together people concerned with Local Communities, Virtual Communities and Communities of
Practice; and (b) bringing together the researchers and practitioners (developers, leaders
and participants) in these three domains. (Virtual) Community Informatics promotes the
cross-fertilization found at this cross-roads, bringing together researchers and
practitioners from many varied disciplines.
The workshop will focus on opportunities and techniques to support both
virtual and local communities, as well as communities of practice. Practitioners building
and participating within communities are welcome, as are those building tools and process
support for communities, as well as researchers.
