In this 19th edition, EPIA 2019, took place in Vila Real at the University of Trás-os-Montes and Alto Douro (UTAD), duringSeptember3–6,2019(https://epia2019.utad.pt/).VilaRealisabeautifultownin theheartofDouroValley,aprivilegedwineregioninPortugal.Thisisanelectedplace for the lovers of nature, food, and wine, whose people are well known for their hospitality.

This conference is always organized under the auspices of the Portuguese Association for Artificial Intelligence (APPIA – http://www.appia.pt) and, as in previous editions, the program was based on a set of thematic tracks dedicated to specific themes of AI. EPIA 2019 encompassed a record of 18 tracks devoted to different topics, plus a doctoral symposium and a panel session on “Societal AI.” The selected tracks were: AIEd - Artificial Intelligence in Education, AI4G - Artificial Intelligence for Games, AIoTA-ArtificialIntelligenceandIoTinAgriculture,AIL-ArtificialIntelligenceand Law, AIM - Artificial Intelligence in Medicine, AICPDES - Artificial Intelligence in Cyber-Physical and Distributed Embedded Systems, AIPES - Artificial Intelligence in Power and Energy Systems, AITS - Artificial Intelligence in Transportation Systems, ALEA-ArtificialLifeandEvolutionaryAlgorithms,AmIA-AmbientIntelligenceand Affective Environments, BAAI - Business Applications of Artificial Intelligence, GAI-GeneralAI,IROBOT-IntelligentRobotics,KDBI-KnowledgeDiscoveryand Business Intelligence, KRR - Knowledge Representation and Reasoning, MASTA-Multi-AgentSystems:TheoryandApplications,SSM-SocialSimulationand Modelling,andTeMA-TextMiningandApplications. The conference program included three invited talks. Marco Dorigo (Université Libre de Bruxelles, Belgium) with a talk on “Swarm robotics: recent results and new research directions,” Michael Wooldridge (University of Oxford, UK) with a talk on “Understanding Equilibrium Properties of Multi-Agent Systems,” and Albert Bifet (Telecom ParisTech, France) with a talk on “Machine Learning for Data Streams.” Forthisedition,252papersubmissionswerereceivedfrom55differentcountriesto the thematic tracks. After a careful review process, 125 papers were selected to be presented in EPIA 2019. The papers acceptance rate was circa 49%. All of the papers were carefully revised by at least three reviewers of the corresponding track Program Committee. We thank the track organizing chairs, together with their respective Program Committee members, for their hard work of scientific reviewing. vi Preface Thanks are also due to all supporting organizations and conference sponsors, startingwithSISCOG,ourmainsponsortowhomwesincerelyaddressourthanks,but alsoDevscope.WewouldliketoexpressourgratitudetoalltheOrganizingCommittee colleagues and track organizers. A special mention to Eduardo Solteiro Pires, José Boaventura Cunha, Teresa Paula Perdicoúlis, Tatiana Pinho, and Goreti Marreiros for their excellent work which was crucial for the successful realization of EPIA 2019.
