This volume contains the original contributions accepted for presentation at the 13th International Conference of the Catalan Association for Artificial Intelligence (CCIA'2010), held in the cave surrounded town of L'Espluga de Francolí, on October 20–22, 2010.

The Catalan Association for Artificial Intelligence (ACIA)

AClA is a member of ECCAI, the European Coordinating Committee for Artificial Intelligence (http://www.acia.org). Its name is an acronym of Associació Catalana d'Intel·ligència Artificial.

The collaboration between ACIA members and the world AI community at large is well-established for many decades now. The papers submitted to the conference reflect that long-standing collaboration; most of its authors come from Catalan-speaking regions of Spain, but also from neighboring countries such as France and Italy, other European Union countries such as the The Netherlands and United Kingdom, and farther countries such as Cuba, Colombia, Brazil and Korea. Over the years, CCIA has become steadily more international as the conference settled itself.

Each of the 43 papers submitted to CCIA'2010 was carefully reviewed by at least 3 program committee members and finally 35 papers have been accepted for presentation during the conference. Of those contributions, the 33 original ones are presented in this volume as well as a brief summary of the two invited talks. The accepted papers, from most of the areas of AI, were divided into 25 oral presentations and 10 posters for organizational purposes, but no difference has been made in the proceedings.

Of all the areas of Computer Science, AI is the one most intertwined with all sorts of disciplines dealt with in the human experience, often employing lessons from one discipline to achieve a task in another one. This diversity is also reflected in the invited talks in this conference: one involving web search, Towards Language-Competent Web Search, presented by Veronica Dahl, Professor at Simon Fraser University, Canada, and the other involving aerospace systems, Autonomy and Artificial Intelligence in Aerospace Systems, presented by Juan de Dalmau, Director of the Aerospace Research and Technology Centre (CTAE), Catalonia.

We would like to express our sincere gratitude to all the authors, who chose this conference to send their work, and to the members of the organizing committee, who took care of the uncountable detailed tasks necessary to have a successful conference. We heartily thank all the members of the Scientific Committee and other reviewers for the hard task of judging the submitted papers. Special thanks go also to the plenary speakers for their effort in preparing very interesting lectures, to Sandra Sandri, former PC chair in CCIA'2009, for her help during this year and, last but not least, to the president of the ACIA, Núria Agell, for her kind and constant support.
