This journal subline serves as a forum for stimulating and disseminating innovative research ideas, theories, emerging technologies, empirical investigations, state-of-the-art methods, and tools in all different genres of edutainment, such as game- based learning and serious games, interactive storytelling, virtual learning environments, VR-based education, and related fields. It covers aspects from educational and game theories, human-computer interaction, computer graphics, artificial intelligence, and systems design. This special issue consists of two parts: the first one features original research papers on interactive digital storytelling in the applied context of edutainment; the second part contains a selection of revised and expanded best papers from the 4th eLearning Baltics (eLBa 2011) conference. The papers on digital storytelling have been split into sections on theory, technology, and case studies; the eLBA 2011 conference papers deal with technology and applications, case studies and mobile applications, and game-based learning and social media.

Emotion pervades human life in general, and human communication in particular, and this sets information technology a challenge. Traditionally, IT has focused on allowing people to accomplish practical tasks efficiently, setting emotion to one side. That was acceptable when technology was a small part of life, but as technology and life become increasingly interwoven we can no longer ask people to suspend their emotional nature and habits when they interact with technology. The European Commission funded a series of related research projects on emotion and computing, culminating in the HUMAINE project which brought together leading academic researchers from the many related disciplines. This book grew out of that project, and its chapters are arranged according to its working areas: theories and models; signals to signs; data and databases; emotion in interaction; emotion in cognition and action; persuasion and communication; usability; and ethics and good practice. The fundamental aim of the book is to offer researchers an overview of the related areas, sufficient for them to do credible work on affective or emotion-oriented computing. The book serves as an academically sound introduction to the range of disciplines involved - technical, empirical and conceptual - and will be of value to researchers in the areas of artificial intelligence, psychology, cognition and user-machine interaction.

This book constitutes the refereed proceedings of the 7th German Conference on Multiagent Systems Technologies, MATES 2009, held in Hamburg, Germany in September 2009 - colocated with the 10th International Workshop on Computational Logic in Multi-Agent Systems (CLIMA X) and the 5th International Workshop on Modelling of Objects, Components, and Agents (MOCA 2009).

The 14 revised full papers, 10 short papers, and 5 exhibition papers presented together with one invited talk were carefully reviewed and selected from 44 submissions. The papers present and discuss the latest advances of research and development in the area of autonomous agents and multiagent systems ranging from theoretical and methodological issues to applications in various fields.

This book constitutes the refereed proceedings of the 5th German Conference on Multiagent Systems Technologies, MATES 2007, held in Leipzig, Germany, in September 2007, co-located with NetObjectDays (NODe 2007).

The 17 revised full papers presented were carefully reviewed and selected from 27 submissions. The papers are organized in topical sections on engineering multi-agent systems, multi-agent planning and learning, multi-agent communication, interaction, and coordination, multi-agent resource allocation, multi-agent planning and simulation, as well as trust and reputation.

The aim of the CEEMAS conference series is to provide a biennial forum for the presentation of multi-agent research and development results. With its p- ticular geographicalorientation towards Central and Eastern Europe, CEEMAS has become an internationally recognised event with participants from all over the world. After the successful CEEMAS conferences in St. Petersburg (1999), Cracow (2001) and Prague (2003), the 2005 CEEMAS conference takes place in Budapest. The programme committee of the conference series consists of est- lished researchers from the region and renowned international colleagues, sh- ing the prominent rank of CEEMAS among the leading events in multi-agent systems. In the very competitive ?eld of agent oriented conferences and workshops nowadays(suchasAAMAS, WI/IAT, EUMAS, CIA, MATES)thespecialpro?le of CEEMAS is that it is trying to bridge the gap between applied research achievements and theoretical research activities. Our ambition is to provide a forum for presenting theoretical research with an evident application potential, implemented application prototypes and their properties, as well as industrial case studies of successful (but also unsuccessful) agent technology deployments. This is why the CEEMAS proceedings volume provides a collection of research and application papers. The technical research paper section of the proceedings (see pages 11-499) contains pure research papers as well as research results in application settings while the application papers section (see pages 500-530) contains papers focused on application aspects. The goal is to demonstrate the real life value and commercial reality of multi-agent systems as well as to foster communication between academia and industry in this ?

The fourth internationalworkshop,"EngineeringSocietiesin the Agents World" (ESAW 2003) was a three-dayevent that took place at the end of October 2003. After previous events in Germany, the Czech Republic, and Spain, the workshop crossed the Channel, to be held at the premises of Imperial College, London. The steady increase in the variety of backgrounds of contributing sci- tists, fascinating new perspectives on the topics, and number of participants, bespeaks the success of the ESAW workshop series. Its idea was born in 1999 among members of the working group on "Communication, Coordination, and Collaboration" of the ?rst lease of life of the European Network of Excellence on Agent-Based Computing, AgentLink, out of a critical discussion about the general mindset of the agent community. At that time, we felt that proper c- siderationsofsystemicaspectsofagenttechnologydeployment, suchasackno- edgement of the importance of the social and environmental perspectives, were sorely missing: a de?ciency that we resolved should be addressed directly by a new forum.

This book constitutes the thoroughly refereed post-proceedings of the Third International Workshop on Engineering Societies in the Agents World, ESAW 2003, held in Madrid, Spain in September 2002. The 20 revised full papers presented were carefully selected from 35 submissions during two rounds of reviewing and improvement. The papers are organized in topical sections on views, models, engineering, and modeling and design.

This book presents 10 chapters on various aspects of intelligent information agents contributed by members of the respective AgentLink special interest group. The papers are organized in three parts on agent-based information systems, adaptive information agents, and coordination of information agents. Also included are a comprehensive introduction and surveys for each of the three parts.

This book constitutes the thoroughly refereed post-proceedings of the Second International Workshop on Engineering Societies in the Agents World, ESAW 2001, held in Prague, Czech Republic in July 2001. The 12 revised full papers presented together with a survey by the volume editors were carefully selected during two rounds of reviewing and improvement. The papers are organized in topical sections on foundations of engineering with agents, logics and languages for MAS engineering, and agent middleware and applications.

Progress in computer animation has gained such a speed that, before long, computer-generated human faces and figures on screen will be indistinguishable from those of real humans. The potential both for scripted films and real-time interaction with users is enormous. However, in order to cope with this potential, these faces and figures must be guided by autonomous personality agents. This carefully arranged volume presents the state of the art in research and development in making synthetic actors more autonomous. The papers describe the different approaches and solutions developed by computer animation specialists, computer scientists, experts in AI, psychologists and philosophers, from leading laboratories world-wide. Finally, a bibliography comprising more than 200 entries enable further study.

This book constitutes the proceedings of the 15th German Conference on Multiagent System Technologies, MATES 2017, held in Lepzig, Germany, in August 2017. The 17 full papers presented in this volume were carefully reviewed and selected from 24 submissions for inclusion in the proceedings. Over these 15 years, the MATES conference series has been aiming at the promotion of and the cross-fertilization between theory and application of intelligent agents and multi-agent systems.

The rich programme of ICIDS 2009, comprising invited talks, technical pres- tations and posters, demonstrations, and co-located post-conference workshops clearly underscores the event's status as premier international meeting in the domain. It thereby con?rms the decision taken by the Constituting Committee of the conference series to take the step forward: out of the national cocoons of its precursors, ICVS and TIDSE, and towards an itinerant platform re?ecting its global constituency. This move re?ects the desire and the will to take on the challenge to stay on the lookout, critically re?ect upon and integrate views and ideas,?ndingsandexperiences,andtopromoteinterdisciplinaryexchange,while ensuring overall coherence and maintaining a sense of direction. This is a signi?cant enterprise: The challenges sought are multifarious and must be addressed consistently at all levels. The desire to involve all research communitiesandstakeholdersmustbematchedbyacknowledgingthedi?erences in established practises and by providing suitable means of guidance and int- duction, exposition and direct interaction at the event itself and of lasting (and increasingly:living) documentation, of which the present proceedings are but an important part.
