Call for Papers (closed)

[pdf version of call for papers]

Artificial Intelligence researchers continue to face huge challenges in their quest to develop truly intelligent systems. The recent developments in the field of neural-symbolic integration bring an opportunity to integrate well-founded symbolic artificial intelligence with robust neural computing machinery to help tackle some of these challenges.

The Workshop on Neural-Symbolic Learning and Reasoning is intended to create an atmosphere of exchange of ideas, providing a forum for the presentation and discussion of the key topics related to neural-symbolic integration. Topics of interest include:


Researchers and practitioners are invited to submit original papers that have not been submitted for review or published elsewhere. Submitted papers must be written in English and should not exceed 8 pages in the case of research and experience papers, and 4 pages in the case of position papers (including figures, bibliography and appendices) in IJCAI format. All submitted papers will be judged based on their quality, relevance, originality, significance, and soundness. Papers must be submitted directly by email in PDF format to nesy@soi.city.ac.uk


Selected papers will be presented during the workshop. The workshop will include extra time for audience discussion of the presentation allowing the group to have a better understanding of the issues, challenges, and ideas being presented.


Accepted papers will be published in official workshop proceedings, which will be distributed during the workshop. Authors of the best papers will be invited to submit a revised and extended version of their papers to a special issue of a major journal to be published early in 2006.

Important Dates

Deadline for submission: 25th of March, 2005.
Notification of acceptance: 25th of April, 2005.
Camera-ready paper due: 16th of May, 2005.
Workshop day: 1st of August, 2005.
IJCAI 2005 main conference dates: 30th of July to 5th of August, 2005.
