The ECAI series of conferences keeps growing. This 18th edition received more submissions than the previous ones. About 680 papers and posters were registered at ECAI 2008 conference system, out of which 518 papers and 43 posters were actually reviewed. The program committee decided to accept
• 121 full papers, an acceptance rate of 23%, and
• 97 posters.
Several submitted full papers have been accepted as posters. All posters, presented in these proceedings as short papers, will have formal presentation slots in the technical sessions of the main program of the conference, as well as 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 & 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 & Multi-agents Systems; Cognitive Modeling & 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 subconference, are also included in this volume.
