7th International Workshop on Uncertainty Reasoning for the Semantic Web


In conjunction with the 10th International Semantic Web Conference


Bonn, Germany

October 23-27, 2011



You are invited to participate in the upcoming workshop on Uncertainty
Reasoning for the Semantic Web (URSW), to be held as part of the 10th
International Semantic Web Conference (ISWC) in October of 2011 at the Hotel
Maritim Bonn, 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.





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

    * Developers of tools designed to support semantic web implementation,
e.g., Jena developers, Protégé developers, OWL-API developers.





We intend to have an open discussion on any topic relevant to the general
subject of uncertainty in the Semantic Web (including fuzzy theory,

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

    * 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.





August 10 Paper submissions due

August 31 Paper acceptance notification

September 5 Camera-ready papers due

October 17 Presentations due

October 23 7th Workshop on Uncertainty Reasoning for the Semantic Web





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 2011 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: . Papers must be
formatted in the style of the Springer Publications format for Lecture Notes
in Computer Science (LNCS). This is the very same format adopted by the ISWC
2011. For complete details, see Springer’s Author Instructions
( ).


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 4 pages.


Following the general acceptance rules of the ISWC 2011 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.





URSW 2011 will be a full-day workshop divided into 4 sessions. The first
session will start with the workshop's keynote presentation, which will be
followed by technical paper presentations. Sessions two and three will be
devoted to presenting our selected technical and position papers, while the

session will be planned in a format that invites an open debate on the
results, conclusions, recommendations, and follow-up work of the URW3-XG
group. We plan to convey a work meeting after the workshop, if the last
session needs to be extended.


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 10-minute slot to share their ideas. After each
presentation, 5 minutes will be allocated to questions from the audience.
Both technical and position papers will be published in the URSW Workshop
proceedings, to be available after the ISWC 2011 Conference.


In addition, technical papers accepted for presentation at the URSW 2011
will be eligible for participating in an international journal special issue
or in a 

post-proceedings book.
