OWLED 2007 Call For Papers

Call For Papers: OWLED 2007. OWL: Experiences and Directions

OWLED 2007
OWL: Experiences and Directions
Third International Workshop
Co-located with ESWC07 and RR2007
Innsbruck, Austria
6-7 June 2007

Submissions due: 4-March-2007
Online submission at

The W3C OWL Web Ontology Language has been a W3C recommendation since 2004. The OWL: Experiences and Direction (OWLED) workshop series is a forum for practitioners in industry and academia, tool developers, and others interested in OWL to describe real and potential applications, to share experience, and to discuss requirements for language extensions/modifications. At OWLED 2006 it was agreed to move forward with a member submission of the OWL 1.1 proposal which extends OWL DL in ways that have been requested by users, that have effective reasoning algorithms, and that developers of OWL reasoning systems are willing to support.

The Third OWL: Experiences and Directions workshop (OWLED 2007) will again bring users, implementors and researchers together in order to measure the current state of need against the state of the art and to set an agenda for language evolutions that satisfy users. OWLED 2007 shall in particular present industrial efforts and experiences with OWL. It shall further the interaction between industry, theoreticians and tool builders, help consolidate OWL 1.1, clarify the relationships between OWL and rules and initiate the specification of OWL 2.0.

Building on the success of the 2005 OWLED and the 2006 OWLED workshops, the 2007 OWLED workshop will again be immediately after one of the main Semantic Web conferences, namely the ESWC conference, and is colocated with the First International Conference on Web Reasoning and Rule Systems, RR2007.


OWLED 2007 welcomes the submission of papers about all aspects of OWL and extensions, application, theory, method, tool, including but not limited to the following topics:

  • All applications of OWL
  • Application-driven requirements for OWL
  • Implementation techniques for OWL and related languages
  • Performance and scalability issues
  • Bridges between knowledge engineering and OWL
  • Non-standard inference services, including explanations, static verification, modularity
  • Enriching ontologies with rules
  • Query answering and data integration
  • Tools for OWL including: editors, visualisation tools, parsers and syntax checkers, versioning frameworks
  • Extensions to OWL including: extended datatype constructors, property constructors, class constructors keys, constraints, rules probabilistic and fuzzy extensions, non-monotonic extensions, temporal and spatial extensions

Submissions of papers on industrial efforts, experiences reports, system descriptions, position papers (especially about new features or issues with OWL), and survey papers about theory or tools (for example comparing different ways of combining rules with OWL) are strongly encouraged. We particularly welcome:

  • Descriptions of industry system or industrial applications
  • Experience reports with OWL or OWL 1.1 (or any fragment or extension) Domain or application ontologies (e-Science, e-Health, e-Culture, e-Learning etc.)
  • Industry requirements
  • Life Sciences or other community requirements
  • Implementation issues with OWL or OWL 1.1
  • Demos with OWL or OWL 1.1
  • Reasoning with OWL and rules in practical applications
  • Requirements for a potential OWL 2.0 revision

Workshop Format

The goal of the workshop will be to maximise discussion. The technical sessions will therefore consist of short presentations of selected papers (grouped by topic area) followed by directed discussion. As in prior years, there will be session(s) devoted to standardization efforts, to some issues deferred from 2006 (alternative syntaxes, constraints, SPARQL and OWL, rules and OWL), and a report, with discussion, on the progress of the OWL 1.1 W3C submission and working group.


Submissions can be either long or short papers. Papers must be no longer than 10 pages. Short submissions no longer than 4 pages are welcome. Interested parties may send the organizers a one page description of their demo.

All submissions must be received before 4 March 2007. All papers must be submitted online using the submission website:

Submissions must be in PDF, and will not be accepted in any other format. It is the responsibility of the authors to ensure that their submission displays and prints correctly on common PDF viewers. Submissions must be formatted in the style of the Springer Publications format for Lecture Notes in Computer Science (LNCS). For details see:,11855,5-164-2-72376-0,00.html


All accepted submissions and demo descriptions will be made available from the workshop web site; these may be updated with final versions after the reviewing process. Final versions of accepted papers will be published on CEUR-WS. Presentation materials from the workshop will also be placed on the web site. All submissions will be reviewed by the workshop committee. Decisions on the acceptance of papers will be communicated to authors no later than 14 April, 2007.

The First International Conference on Web Reasoning and Rule Systems (RR2007)

The International Conference on Web Reasoning and Rule Systems (RR) aims to be the major forum for discussion and dissemination of new results on all topics concerning Web Reasoning and Rule Systems. RR2007 brings together three previously separate events: the International Workshop on Principles and Practice of Semantic Web Reasoning (PPSWR), the International Conference on Rules and Rule Markup Languages for the Semantic Web (RuleML), and the International Workshop on Reasoning on the Web (RoW).

This joint conference is devoted to all aspects of Semantic Web Reasoning, with an emphasis on rule-based approaches and languages. It welcomes both theoretical and practical submissions on this wide subject.

The reasoning landscape features theoretical areas such as knowledge representation (KR) and algorithms; design aspects of rule markup; design of ontology languages; engineering of engines, translators, and other tools; standardization efforts, such as the Rules Interchange Format activity at W3C; and applications. Of particular interest is also the use of rules to facilitate ontology modeling, and the relationships and possible interactions between rules and ontology languages like RDF and OWL, as well as ontology reasoning related to RDF and OWL.

The conference is supported by REWERSE and RuleML, and conveniently co-located with ESWC2007.

The Fourth Annual European Semantic Web Conference (ESWC 2007)

Call for Papers: The vision of the Semantic Web is to enhance today's web via the exploitation of machine-processable meta data. The explicit representation of the semantics of data, enriched with domain theories (Ontologies), will enable a web that provides a qualitatively new level of service. It will weave together a large network of human knowledge and makes this knowledge machine-processable. Various automated services will help the users to achieve their goals by accessing and processing information in machine-understandable form. This network of knowledge systems will ultimately lead to truly intelligent systems, which will be employed for various specialized reasoning subsystems to accomplish complex tasks. Many technologies and methodologies are being developed within Artificial Intelligence, Natural Language Processing, Machine Learning, Databases, Multimedia Systems, Distributed Systems, Software Engineering and Information Systems that can contribute towards the realization of this vision.

The Fourth Annual European Semantic Web Conference (ESWC 2007) will present the latest results in research and application of Semantic Web technologies, including knowledge mark-up languages, Semantic Web services, and ontology management. ESWC 2007 will also feature a special industry-oriented event, a forum for gaining a better understanding of these new technologies and their business aspects. The conference will offer a tutorial program to get up to speed with European and global developments in this exciting new area.

ESWC 2007 is sponsored by ESSI — a group of European Commission 6th Framework Programme projects. Together these projects aim to improve world-wide research and standardisation in the area of the Semantic Web.
