We propose that a 2 month, 10 man study of artificial intelligence be carried out during the summer of 1956 at Dartmouth College in Hanover, New Hampshire. The study is to proceed.... Last year the 50th anniversary of the Dartmouth AI project proposal by McCarthy, Minsky, Rochester and Shannon was celebrated. Years later, and following similar traditions of a number of AI associations, a call was launched in 1997 by the Catalan Association for Artificial Intelligence (ACIA) to organize an annual conference to promote synergies in the research community of its influence, the seeder for the 1st Catalan Conference on Artificial Intelligence (CCIA98) which took place in Tarragona on October 1998. The editors are very glad to celebrate the 10th anniversary of the International Conference of the ACIA (CCIA07) in Sant Julià de Lòria (Andorra), October 2526th, 2007. The good health of the Catalan AI community and its influence area is witnessed by the representative selection of papers gathered in this book and presented at CCIA07. The book is organized according to the different areas in which the papers were distributed for their presentation during the conference, namely: Constraint Satisfaction, Agents, Data Processing, Case-Based Reasoning, Computer Vision, Natural Language Processing, Uncertainty and Fuzziness, Robotics, and Applications. The editors believe that all the papers collected in this volume can be of interest to any computer scientist or engineer interested in AI.
