ECAI 2008

The ECAI series of conferences keeps growing. This 18th edition received more submissions than the previous ones. About 680 papers and posters were registered through the ECAI 2008 conference system, out of which 518 papers and 43 posters were actually reviewed. The program committee decided to accept 121 full papers (acceptance rate 23 per cent) and 97 posters. Several submitted full papers have been accepted as posters. All posters, presented in these proceedings as short papers, are formally presented in the technical sessions of the main program of the conference, as well as at the poster presentations within a specific session. With respect to previous ECAI conferences, one may notice a relative growth of the Machine Learning and Cognitive Modeling and Interaction areas. The rest of the distribution remains about stable, with marginal fluctuations given that areas are overlapping and their frontiers are not sharp.Papers are accepted in the following research areas: KR&R; Machine Learning; Distributed and Multi-agents Systems; Cognitive Modeling and Interaction; Constraints and search; Model-based Reasoning and Diagnosis; NLP; Planning and scheduling; Perception, Sensing and Cognitive Robotics; and, Uncertainty in AI.
The accepted papers of the Prestigious Applications of Intelligent Systems (PAIS), ECAI's associated sub conference, are also included in this volume.
