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

	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, Protégé and Protégé-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	4rd 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.
