With this edition, EPIA, the Portuguese Conference on Arti?cial Intelligence, celebrates its 20th anniversary.Like all its previous editions, it has been run - der the auspices of the Portuguese Association for Arti?cial Intelligence (APPIA), which was established in 1984 and is also celebrating 20 years of activity. The ?rst edition of EPIA was held in Porto, in October 1985, organised by Pavel Brazdil, Miguel Filgueiras, Lu 's Damas and Armando Campos e Matos. EPIA soon evolved to an international conference by adopting in its fourth edition English as the o?cial language and having its proceedings published by Springer, intheLNAIseries.Inrecentyears, theconferencegraduallyprogressed from a plenary organisation to a workshop-based structure. The conference has steadily assumed high-quality standards, both in its scienti?c management and in the scienti?c program, with the aim of progressively broadening its audience and improving its impact over young researchers. EPIA2005wasthe12theditionoftheconference.With theabove-mentioned celebrations in mind, we decided to work towards the involvement of several generations of AI researchersin the organisationof the event. As a result, EPIA 2005 involved for the ?rst time an Advisory Committee, composed of all the founders of APPIA that are still working in AI, and also the Co-chairs of the lastEPIAs, as listed elsewherein these proceedings.We wantto express to them our gratitude for all the support, advice and con?dence.

This book constitutes the refereed proceedings of the 8th Portuguese Conference on Artificial Intelligence, EPIA '97, held in Coimbra, Portugal, in October 1997.
The volume presents 24 revised full papers and 9 revised posters selected from 74 submissions from various countries. Also included are two full invited papers and two abstracts of invited talks. The papers are organized in topical sections on automated reasoning and theorem proving; CBR and machine learning; constraints; intelligent tutoring; knowledge representation; multi-agent systems and DAI; nonmonotonic, qualitative and temporal reasoning, and problem solving.

Computational creativity is an emerging field of research within AI that focuses on the capacity of machines to both generate and evaluate novel outputs that would, if produced by a human, be considered creative. This book is intended to be a canonical text for this new discipline, through which researchers and students can absorb the philosophy of the field and learn its methods. After a comprehensive introduction to the idea of systematizing creativity the contributions address topics such as autonomous intentionality, conceptual blending, literature mining, computational design, models of novelty, evaluating progress in related research, computer-supported human creativity and human-supported computer creativity, common-sense knowledge, and models of social creativity. Products of this research will have real consequences for the worlds of entertainment, culture, science, education, design, and art, in addition to artificial intelligence, and the book will be of value to practitioners and students in all these domains.

This book constitutes the refereed proceedings of the 17th Portuguese Conference on Artificial Intelligence, EPIA 2015, held in Coimbra, Portugal, in September 2015. The 45 revised full papers presented together with 36 revised short papers were carefully reviewed and selected from a total of 131 submissions. EPIA 2015, following the standard EPIA format, covers a wide range of AI topics as follows: ambient intelligence and affective environments, artificial Intelligence in medicine, artificial intelligence in transportation systems, artificial life and evolutionary algorithms, computational methods in bioinformatics and systems biology, general artificial intelligence, intelligent information systems, intelligent robotics, knowledge discovery and business intelligence, multi-agent systems: theory and applications, social simulation and modelling, text mining and applications.
