“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 we celebrated the 50th anniversary of the Dartmouth AI project proposal by McCarthy, Minsky, Rochester and Shannon. 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

ACIA, the Catalan Association for Artificial Intelligence, is member of the European Coordinating Committee for Artificial Intelligence (ECCAI). http://www.acia.org.

We are very glad to celebrate this year the 10th anniversary of the International Conference of the ACIA (CCIA'07) in Sant Julià de Lòria (Andorra), October 25–26th, 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 which were presented at CCIA'07.

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. Papers have been selected after a double blind review process in which distinguished AI researchers from all over Europe participated. Among the 54 papers received, 23 were selected as oral presentations and 23 as posters. The quality of the papers was very high in average, and the selection between oral or poster presentation was only based on the potential degree of discussion that a paper we thought could generate. We believe that all the papers collected in this volume can be of interest to any computer scientist or engineer interested in AI.

We would like to express our sincere gratitude to all the authors and members of the scientific and organizing committees that have made this conference a success. Our special thanks go also to the plenary speakers, Gábor Lugosi and Jordi Vitrià, for their effort in preparing very interesting lectures, and to the president of the ACIA, Núria Agell, for her kind support.
