The papers in this volume are the refereed papers presented at AI-2011, the 31st SGAI International Conference on Innovative Technologies and Applications of Artificial Intelligence, held in Cambridge in December 2011 in both technical and applied flows. They introduce new and innovative developments and applications, divided into technical flow sections on planning, evolutionary algorithms, speech and vision, and machine learning, followed by application flow sections on knowledge discovery and data mining, machine learning, and artificial intelligence in action. The volume also includes texts of short papers presented as posters at the conference. This is the twenty-eighth volume in the "Research and Development in Intelligent Systems" series, which also includes the nineteenth volume in the Applications and Innovations in Intelligent Systems series. These series are essential reading for those who wish to keep abreast of developments in this important field.
