ASCII version of the Call for Papers.

Call for Papers

We invite submissions of technical papers of 8 pages and short position papers (for people that want to participate in the workshop without giving talks). Authors of accepted technical and position papers will be invited to participate in the workshop (participation will be by invitation only).

Accepted technical papers will be included in the proceedings. The workshop proceedings will be distributed in paper form at the workshop, and will be made available electronically in the CEUR Workshop Proceedings series.

Important Dates

Paper submission deadline: (new) June 1, 2003
Notification of acceptance: (new) June 30, 2003
Camera ready papers due: (new) July 18, 2003
DL'03 Workshop: September 5-7, 2003


We invite contributions on all aspects of Description Logics. Possible subjects include:


Interested parties are invited to submit

Both kinds of submission should be formatted similar to previous Description Logics workshops, following this example LaTeX file. You can also view compiled postscript and PDF versions of this example file, which contains some more explanations concerning the requested style. Please avoid headers, footers, and page numbering.

The use of LaTeX is encouraged but not mandatory. If for some reason LaTeX cannot be used, print out the postscript or PDF version of the example submission and produce by any means a postscript or PDF file with the same margins and possibly the same layout for sections and bibliography. A Microsoft Word style file is not available.

Submissions should be sent by electronic mail as standard postscript or PDF attachments to


and must arrive before June 1, 2003. If you have any difficulties with the requested document format (e.g., because you do not use LaTeX or cannot generate postscript or PDF files), do not hesitate to contact the workshop organizers at dl03@dis.uniroma1.it

Please include in the email (in plain text) the title, author(s), contact name/email, and a short abstract of the paper, e.g.:

Title: The Tractability of Subsumption in Frame-Based Description Languages
Author: Ronald J. Brachman and Hector J. Levesque

Abstract: A knowledge representation system provides an important service to the rest of a knowledge-based system: it computes automatically a set of inferences over the beliefs encoded within it. Given that the knowledge-based system relies on these inferences in the midst of its operation (i.e., its diagnosis, planning, or whatever), their computational tractability is an important concern. Here we present evidence as to how the cost of computing one kind of inference is directly related to the expressiveness of the representation language. As it turns out, this cost is perilously sensitive to small changes in the representation language. Even a seemingly simple frame-based description language can pose intractable computational obstacles.
