Short papers present original, previously unpublished work that make a novel research contribution to the field. They provide an opportunity to describe significant work in progress or research that is best communicated in an interactive or graphical format. Compared to full papers, their contribution may be narrower in scope, be applied to a narrower set of application domains, or have weaker empirical support than that expected for a full paper. Submissions likely to generate discussions in new and emerging areas are especially encouraged.

Accepted submissions where authors fail to register by the early deadline or cannot attend to present are subject to being withdrawn from the conference proceedings at the discretion of the chairs.
