Submissions of the following three types are invited:

Type A: REGULAR PAPERS

Papers presenting new original work. Submitted papers should not exceed a length of 8 pages. These papers will be reviewed on overall quality and relevance. A-Papers can be accepted for either oral or poster presentation. All accepted papers will be fully published in the proceedings.

Type B: COMPRESSED CONTRIBUTIONS

Papers that have been accepted after June 1st, 2008 for AI-related refereed conferences or journals can be resubmitted and will be accepted as compressed contributions. Authors are invited to submit the officially published version (without page restriction) together with a one or two-page abstract. B-Papers will be accepted for either oral or poster presentation. The abstract of the paper will be published in the proceedings. Every author may submit at most one B-paper of which they are the corresponding author, and only if they do not submit any A-paper as corresponding author.

Type C: DEMONSTRATIONS & APPLICATIONS

Proposals for demonstrations will be evaluated based on submitted demonstration summaries stating the following: the purpose of the system to be demonstrated, its user groups, the organization or project for which it is developed, the developers, and the technology used. In addition, the system requirements and the duration of the demo (not exceeding 30 minutes) should be mentioned. Especially master students are encouraged to submit papers presenting their applications and experiences. The maximum size of demonstration summaries is 2 pages (in English).

Researchers from industry are encouraged to submit papers presenting their applications and experiences to the Industry Track.

Papers and demonstration summaries should be submitted electronically by June 12th, 2009. Submission implies willingness of at least one author to register for BNAIC'09 and present the paper. For each paper, a separate author registration is required. Authors keep the copyright of their submissions. The BNAIC Proceedings are published under ISSN series number 1568-7805.
