           4th Workshop on Uncertainty Reasoning for the Semantic Web

                          In conjunction with the

                            Karlsruhe - Germany

********************************************************************************

	You are invited to participate in the upcoming workshop on Uncertainty
Reasoning for the Semantic Web (URSW), to be held as part of the 7th
International Semantic Web Conference (ISWC) in October of 2008 in  
Karlsruhe -
Germany.
     ISWC is a major international forum for presenting visionary  
research
on all aspects of the Semantic Web. The Uncertainty Reasoning Workshop  
is an
exciting opportunity for collaboration and cross-fertilization between  
the
uncertainty reasoning community and the Semantic Web community.
     Effective methods for reasoning under uncertainty are vital for  
realizing
many aspects of the Semantic Web vision, but the ability of current- 
generation
web technology to handle uncertainty is extremely limited. Recently,  
there has
been a groundswell of demand for uncertainty reasoning technology  
among Semantic
Web researchers and developers.
     This surge of interest creates a unique opening to bring together  
two
communities with a clear commonality of interest but little history of
interaction. By capitalizing on this opportunity, URSW could spark  
dramatic
progress toward realizing the Semantic Web vision.

Audience

The intended audience for this workshop includes the following:
- Researchers in uncertainty reasoning technologies with interest in  
Semantic
   Web and Web-related technologies.
- Semantic web developers and researchers.
- People in the knowledge representation community with interest in the
   Semantic Web.
- Ontology researchers and ontological engineers.
- Web services researchers and developers with interest in the  
Semantic Web.
- Developers of tools designed to support semantic web implementation,  
e.g.,
   Jena developers, Protege and Protege-OWL developers.

Topic List

We intend to have an open discussion on any topic relevant to the  
general
subject of uncertainty in the Semantic Web (including fuzzy theory,  
probability
theory, and other approaches). Therefore, the following list should be  
just an
initial guide.
- Syntax and semantics for extensions to Semantic Web languages to
    enable representation of uncertainty
- Logical formalisms to support uncertainty in Semantic Web languages
- Probability theory as a means of assessing the likelihood that terms  
in
   different ontologies refer to the same or similar concepts  
Architectures for
   applying plausible reasoning to the problem of ontology mapping
- Using fuzzy approaches to deal with imprecise concepts within  
ontologies
- The concept of a probabilistic ontology and its relevance to the
   Semantic Web
- Best practices for representing uncertain, incomplete, ambiguous, or
   controversial information in the Semantic Web
- The role of uncertainty as it relates to Web services Interface  
protocols with
   support for uncertainty as a means to improve interoperability  
among Web
   services
- Uncertainty reasoning techniques applied to trust issues in the  
Semantic Web
- Existing implementations of uncertainty reasoning tools in the  
context of the
   Semantic Web
- Issues and techniques for integrating tools for representing and  
reasoning
    with uncertainty
- The future of uncertainty reasoning for the Semantic Web

Important Dates

July 25, 2008	        Paper submissions due
September 5, 2008	Paper acceptance notification
September 26, 2008	Camera-ready papers due
October 26, 2008	4th Workshop on Uncertainty Reasoning for the  
Semantic Web

Submission Details

The URSW will be accepting submissions of technical papers and position
papers. Each submission will be evaluated for acceptability by at  
least three
members of the Program Committee. Decisions about acceptance will be  
based on
relevance to the above topic list, originality, potential significance,
topicality and clarity. Since all accepted papers will be presented at  
the
workshop, we require that at least one of the submitting authors must  
be a
registered participant at the ISWC 2008 Conference, and committed to  
attend the
URSW Workshop.

Submissions to the Workshop are only accepted in electronic
format and should be sent via the workshop's submission site:
http://www.easychair.org/conferences/?conf=ursw2008. Papers must be  
submitted in
PDF format, and follow the same submission format used by the ISWC 2008
Conference, the Springer Publications format for Lecture Notes in  
Computer
Science (LNCS), available at
http://www.springeronline.com/sgw/cda/frontpage/0,11855,5-164-2-72376-0,00.html

Technical papers submitted to the URSW Workshop must not exceed 12  
pages,
including figures. Submissions exceeding this limit will not be  
reviewed.
Position papers consist of a summary of ideas, projects, or any  
research efforts
that are relevant to the URSW Workshop and must not exceed 2 pages.

Following the general acceptance rules of the ISWC 2008 conference,  
papers that,
at the time of submission, are under review for or have already been  
published
in or accepted for publication in a journal or another conference will  
not be
accepted to the URSW workshop.

Presentation and Publication

URSW 2008 will be a full day workshop with four sessions. Two of those  
sessions
will be devoted to a specific theme, while the remaining sessions will  
be
planned in a format that invites an open debate on the results,  
conclusions,
recommendations, and follow-up work of the W3C Uncertainty Reasoning  
for the
World Wide Web Incubator Group
( http://www.w3.org/2005/Incubator/urw3/XGR-urw3/ ).

All papers accepted to the URSW will be presented during the workshop  
and
published in the workshop proceedings, which will be available as a  
separate
publication after the Conference. Authors of accepted technical papers  
will
have 20 minutes to present their work, while authors of accepted  
position
papers will have a 5-minute slot to share their ideas. In addition, both
technical and position papers will be published in the URSW Workshop
proceedings, to be available after the ISWC 2008 Conference.
