The Twenty-Fifth Annual Conference on Innovative Applications of Artificial Intelligence (IAAI-13) will be held July 14–18, 2013 in Bellevue, Washington, USA. The conference will focus on successful applications of AI technology. The conference will use technical papers, invited talks, and panel discussions to explore issues, methods, and lessons learned in the development and deployment of AI applications; and to promote an interchange of ideas between basic and applied AI. IAAI-13 will consider papers in two tracks: (2) deployed application case studies and (1) emerging applications or methodologies. Submissions should clearly identify which track they are intended for, as the two tracks are judged on different criteria. Applications are defined as deployed once they are in production use by their final end users (not the people who created the application) for sufficiently long that experience can be reported (usually greater than three months of use by the end users). All submissions must be original.
