CFP: EON2006 Workshop at WWW2006: Evaluation of Ontologies for the Web

Apologies for cross-posting. Please forward this mail to anyone interested.



4th International EON Workshop
Workshop on Evaluation of Ontologies for the Web (EON2006)

Held in conjunction with the
15th International World Wide Web Conference

Edinburgh International Conference Center, Edinburgh, UK
May 22nd or 23rd (to be defined), 2006



In the successful series of EON workshops we intend to bring together
researchers and practitioners from the quickly developing research areas
Ontologies and Semantic Web. Former EON workshops aimed at evaluating
ontology-based tools, this year?s workshop  focuses on the Evaluation of
Ontologies (content, usability, etc.) themselves. Whereas some effort
already was invested in reusing work from related research areas towards
the end of Ontology Evaluation, often the basic premises of the web-like
environment are forgotten or disregarded. Thus the main goal of this
workshop is to lay the foundations for Web Ontology Evaluation.

Ontologies now play an important role for many knowledge-intensive
applications for which they provide a source of formally defined terms.
They aim at capturing domain knowledge in a generic way and provide a
commonly agreed understanding of a domain, which may be reused, shared,
and operationalized across applications and groups. Numerous ontologies
are already available and the number is growing rapidly. Still a well
understood definition or even intuition about qualities that apply to
ontologies is lacking. The large visibility of the Semantic Web already
attracts industrial partners. Ontology-based tools depend more and more
on the explicit knowledge captured in ontologies. A well-understood
notion of Ontology Evaluation might lead to a consistent level of
quality and thus acceptance by industry. For the future this might lead
to certification efforts for such ontologies.

The aim of this workshop is to ground Ontology Evaluation firmly on the
needs of the Semantic Web, especially regarding its web-like
characteristics like high interconnectivity, constant change and
incompleteness. We will focus on the Semantic Web languages as
standardized or proposed by the W3C: RDF(S), OWL and the rule language.
We want to encourage and stimulate discussion about the current state of
the art in Ontology Evaluation and its future direction. Currently,
ontologies and the Semantic Web attract researchers from all around the
world and from various disciplines, sometimes forgetful of the new needs
and conditions arising from the Semantic Web?s requirements.

Main topics of interest include but are not limited to:
* Web Ontology Evaluation
* Ontology Evaluation Methodologies
* Tools for Ontology Evaluation
* Ontology Content Evaluation
* Task-oriented Evaluation / Task-independent Evaluation
* Criteria for Ontology Content Evaluation
* Formal/Informal Ontology Evaluation
* Evaluation of Heavily Interconnected Ontologies / Networks of Ontologies
* Ontology Metrics-based Evaluation
* Evaluation-guided revision of Ontologies
* Certification of Ontologies


To ensure a creative atmosphere during the workshop, the participants
will be selected based on their submitted papers, posing important
issues to be presented and discussed at the workshop. The workshop will
consist of short presentations followed by discussions about the goals
of the workshop: the state of the art in Ontology Evaluation with
regards to the needs of the Semantic Web and outlining a plan for future
research. Also there will be a practical session, where three ontologies
are to be evaluated by the participants beforehand and the results being
discussed at the workshop. In order to obtain an intensive exchange of
ideas between the participants, there will be left extensive time for

The previous workshops (EON2002, EON2003 and EON2004) proposed a series
of experiments for evaluating different aspects of ontology tools, e.g.
their expressiveness and interoperability capabilities. The aim of the
EON series is to attract attention to a number of evaluation topics
since we believe this to be a highly relevant issue for the adaptation
of Semantic Web technologies by partners outside the Semantic Web community.

This year we focus on ontologies themselves. Taking into account the
success of the former workshops in this series, we will not only expect
regular contributions on any of the topics addressed in this CFP, but we
will also look forward to receiving submissions based on experimental
results, surveys and tools for Ontology Evaluation. The EON2006 workshop
is intended to be a platform to discuss results and further steps with
interested parties. Along with these experimental contributions, we
explicitly encourage people to make demos of their tools. We will
reserve time slots for demos in the workshop.

Prior the workshop all participants will be asked to evaluate three
ontologies according to their approaches. The workshop will facilitate
discussion by comparing the results of the participants. This is not
meant as a test or as homework, as we don?t know the correct results
ourselves yet ? it is the goal of this workshop to answer this very
question. The ontologies will be downloadable at the workshop?s website.

A final panel will discuss the research agenda for the coming years,
based on the presentations and results from the demos, evaluations and


Deadline paper submissions: January 10th, 2006
Notification of acceptance: February 1st, 2006
Camera ready deadline: February 15th, 2006
Workshop: May 22nd or 23rd (to be defined), 2006


Interested authors should submit an electronic PDF and source version of
their papers to [hidden email] prior to the paper
submission deadline. The first page of submitted papers should include:
title, author names, affiliations, postal addresses, electronic mail
addresses, telephone and fax numbers for all authors, and a brief
abstract. All correspondence will be sent to the author mentioned as
contact person in the electronic title page (by default, the first
author). Submissions should not exceed 8 pages and should be formatted
according to the guidelines of the WWW conference (see ). We also welcome position
papers no longer than 4 pages.
