ECAI 2014 Frontiers in Artificial Intelligence and Applications FAIA covers all aspects of theoretical and applied artificial intelligence research in the form of monographs, doctoral dissertations, textbooks, handbooks and proceedings volumes. The FAIA series contains several sub-series, including “Information Modelling and Knowledge Bases” and “Knowledge-Based Intelligent Engineering Systems”. It also includes the biennial ECAI, the European Conference on Artificial Intelligence, proceedings volumes, and other ECCAI – the European Coordinating Committee on Artificial Intelligence – sponsored publications. An editorial panel of internationally well-known scholars is appointed to provide a high quality selection. Series Editors: J. Breuker, N. Guarino, J.N. Kok, J. Liu, R. López de Mántaras, R.

Introduction ThisvolumecontainstheproceedingsoftheTwenty-firstEuropeanConferenceonArtificialIntelligence(ECAI’14), held from August 18 to 22, 2014 in Prague, Czech Republic. Since 1974, the biennial European Conference on ArtificialIntelligence, organized bythe EuropeanCoordinatingCommittee forArtificial Intelligence(ECCAI),has beenthepremiervenueforpresentingAIresearchinEurope. ECAIistheplaceforresearchersandpractitionersof ArtificialIntelligence(AI)togatherandtodiscussthelatesttrendsandchallengesinallsubfieldsofAIaswellasto demonstrateinnovativeapplicationsandusesofadvancedAItechnology. As in past editions, ECAI’14 was accompanied by the Conference on Prestigious Applications of Intelligent Systems (PAIS 2014), from which the papers are also included in this volume, and the Starting AI Researcher Symposium(STAIRS),thepapersofwhicharepublishedinaseparatevolume. Moreover,theprogramofECAI’14 includes four invited plenary talks, several invited talks in the “Frontiers of Artificial Intelligence” track, as well as anextensiveworkshopandtutorialprogram. In total, 611 papers were submitted to ECAI’14, viz. 562 long and 49 short papers. Of these, 158 (28%) and 20 (41%) were accepted, respectively, as well as 89 long papers, which were accepted as short papers. Similar to previous ECAI conferences, the largest areas of submission were ‘Knowledge Representation, Reasoning, and Logic’,followedby‘Agent-basedandMulti-agentSystems’and‘MachineLearningandDataMining’. Iwas luckytobe partofa wonderfulandhighly dedicatedteam: Iwouldlike tothankMarina DeVosand Karl Tuylsforputtinginplaceanextensiveworkshopprogram,AgostinoDovierandPaoloTorroniforattractingexciting tutorials, Joa˜o Leite and Ulle Endriss for their devotion to STAIRS’14, and last but not least Gerhard Friedrich and Barry O’Sullivan for chairing PAIS’14 as well as organizing the system demonstration track. I would also like to thank the local organizers Vladim´ır Maˇr´ık, Olga Sˇteˇpa´nkova´, and Filip Zˇelezny´ for our constructive collaboration. A special thanks goes to Zuzana Sˇeps for having always been there when needed! I also benefited a lot from the experience, material, and advice obtained from my two predecessors, Luc De Raedt and Michael Wooldridge. Similarly, I would like to thank the members of the ECCAI board for their advice and guidance. I am indebted to ThomasPreussforhisconstantsupportwithConfMaster. Ofcourse,itgoeswithoutsayingthatmylifewouldhave been truly miserable without the great support of my group: Holger Jost, Philip Obermeier, Javier Romero, Orkunt Sabuncu,RolandKaminski,BenjaminAndres,andMaxOstrowski. Andfinally,thankstoallPCandSPCmembers, reviewers,sponsors,andallauthorswhosubmittedtoECAI’14. SeeyouallinPrague!
