Foreword: This book contains the proceedings of the 4th International Conference on Agents and Artificial Intelligence (ICAART 2012) which was organized by the Institute for Systems and Technologies of Information, Control and Communication (INSTICC). ICAART 2012 was held in cooperation with the Portuguese Association for Artificial Intelligence (APPIA), the Spanish Association for Artificial Intelligence (AEPIA) and the Association for the Advancement of Artificial Intelligence (AAAI). The Conference Program includes oral presentations (full papers and short papers) and posters, organized in two simultaneous tracks: “Artificial Intelligence” and “Agents”. We are proud to inform that that the program includes also five plenary keynote lectures, given by internationally distinguished researchers, namely – Helder Coelho (University of Lisbon), Anthony G. Cohn (University of Leeds), Frank Dignum (Utrecht University), Luís Paulo Reis (University of Minho / LIACC) and Wolfgang Wahlster (German Research Center for AI). ICAART received 292 paper submissions from 52 countries, in all continents. To evaluate each submission, a double blind paper review was performed by the Program Committee, whose members are highly qualified researchers in ICAART topic areas. Based on the classifications provided, only 113 papers were selected for oral presentation (42 full papers and 71 short papers) and 36 papers were selected for poster presentation. The full paper acceptance ratio was 14%, and the total oral acceptance ratio (including full papers and short papers) 39%. These strict acceptance ratios show the intention to preserve a high quality forum which we expect to develop further next year. All papers presented at this conference will be available at the SciTePress Digital Library. A short list of the presented papers will be selected so that revised and extended versions of these papers will be published by Springer-Verlag in a CCIS Series book, with the best papers of ICAART 2012. A few papers will also be invited for publication in a special issue of JOPHA - Journal of Physical Agents, as revised extended versions of conference papers. Besides, a short list of papers presented at the conference will be selected for publication of extended and revised versions in a special issue of Springer's LNCS TCCI Journal. Conferences are also meeting places where collaboration projects can emerge from social contacts amongst the participants. Therefore, in order to promote the development of research and professional networks the Conference includes in its social program a Conference Social Event & Banquet in the evening of February 7th (Tuesday). We would like to express our thanks to all participants. First of all to the authors, whose quality work is the essence of this conference; secondly to all members of the Program Committee and auxiliary reviewers, who helped us with their expertise and valuable time. We would also like to deeply thank the invited speakers for their excellent contribution in sharing their knowledge and vision. Finally, a word of appreciation for the hard work of the secretariat: organizing a conference of this level is a task that can only be achieved by the collaborative effort of a dedicated and highly capable team. The organization will distribute four paper awards at the conference closing session, two for the Agents track and two for the Artificial Intelligence track: each track will have a best paper award and a best student paper award. The decision is mainly based on the paper classifications provided by the Program Committee and the paper presentation at the conference, assessed by the session chairs. We wish you all an inspiring conference and an unforgettable stay in the lovely city of Vilamoura. We hope to meet you again next year for the 5th ICAART, details of which will soon be available at http://www.icaart.org. (More)
