Call for Papers "Identity and Reference in web-based Knowledge Representation" workshop


IR-KR2009 at IJCAI-09

July 11-13, 2009
Pasadena, CA, USA

The IJCAI-09 Workshop on
"Identity and Reference in web-based Knowledge Representation" (IR-KR2009)

July 11-13, 2009
Pasadena, California, USA

held at the International Joint Conference on Artificial Intelligence

-- IR-KR2009 goals --

The goal of this workshop, which in past years was mainly organised
within the Web and Semantic Web (SW) communities (see past editions at
WWW2006, WWW2007, ESWC200q8), is to widen debate on the impact and the
challenges that the notions of *identity* and *reference* in
web-oriented KR poses to some of the core concepts of AI.

-- Background & Description of the workshop --

The Semantic Web initiative advances the idea that the web may become
a space not only for publishing and interlinking documents (through
HTML hyperlinks), but also knowledge bases (e.g. in the form of RDF
graphs) in an open and fully decentralized environment.

Even though models and languages used to implement the nascent
Semantic Web have been taken from long-standing research in AI, SW and
AI have different priorities. While traditionally a strong focus
within AI has been developing theories and code to support sound and
complete reasoning, web-oriented KR has a primary concern of web-wide
information interoperability and integration.

Perhaps the most central issue in reconciling these concerned is the
Principle of Global Identifiers: "global naming leads to global
network effects" (see Architecture of the World Wide Web, Volume One,
2004, at As for the
web of documents, the overall value of such open and distributed
network of truly interlinked knowledge sources, based on global names,
would be immensely bigger than the sum of the value of the components.

This central role of identity and reference for a web-scale KR poses
new challenges to traditional KR, and many researchers have suggested
that the concept of URI may deeply affect the notions of language
(e.g. the semantics of using the "same" URI in different models),
reference (e.g. rigid vs. non rigid designation), interpretation
(e.g. the meaning of "links" across knowledge bases) & reasoning
(e.g. distributed reasoning across theories) in traditional
logic-based KR in AI. This workshop addresses these challenges.

-- Expected outcome --

The anticipated outcome of the workshop is to assess the state of the
art in the area of Identity and Reference in AI and the SW, and to go
beyond the limited scope of the current Semantic Web, as well as to
discuss and critically evaluate approach and next steps in
implementing and reasoning about identity and reference. It is
expected that the workshop will provide a valuable opportunity for
cross-fertilization across different research communities.

-- Workshop format --

Based on the successful experience in the past workshops on this
topic, the format of IR-KR2009 will be the following:

    * a keynote talk that illustrates the importance of the topic
    * very short presentations of the accepted papers, to give
      participants an overview of the research work of the main
      workshop contributors
    * presentation of a detailed list of topics to discuss, by the
      workshop chair
    * extensive, moderated plenary discussion
    * collaborative write-up of conclusions and next steps

-- Submissions --

The workshop aims at collecting contributions which can roughly be
grouped as follows:

    * Foundations: formal and conceptual theories of identity and
      reference for web-oriented KR
    * Formal theories: semantics for KR on the web, soundness and
      completeness of web-oriented reasoning, semantics of interlinked
    * Vision papers: visionary solutions to the problems of identity
      and reference in KR
    * Project papers: descriptions of research & development projects
      in this area
    * Experiences: contributions from research and industry that
      illustrate case studies or approaches to deal with the issues of
      identity and reference on a web-scale
    * Critical viewpoints: discussions of advantages and disadvantages
      of the proposed approaches

We especially encourage contributions from groups or organizations
which are working on assembling large knowledge-based data collections
in order to compare the different practical solutions which were found
for integrating semantic data from multiple sources.

-- Submission Requirements and Dates --

IR-KR2009 will accept submissions for full papers, posters and
demonstrations. The selection will be based on the significance and
the quality of submissions as well as oriented towards fostering
cross-pollination and discussions during the event. All selected
abstracts will be included in the IJCAI-09 Working Notes. Authors are
kindly requested to provide keywords upon submission. The format for
submissions is the same as that of IJCAI-09. Please check for the style files. Submissions should be no
longer than 5 pages.

- Submission deadline (papers, posters, demos): March 6, 2009
- Notification to authors: April 17, 2009
- Camera-ready version: May 8, 2009
- Workshop dates: July 11-13, 2009

Submissions will be managed through at:

-- Attendance --

Following IJCAI-09 policy, the total number of participants in
IR-KR2009 will be limited to 75 people. This includes organizers, PC
members, invited speakers, authors and attendees. Authors will be
selected based on the significance of their submission and will be
preferred during registration to non-presenting
attendees. Non-presenting attendees will be selected on a
first-come-first-served basis. Please refer to for
the application procedure and fees.
