This book constitutes the refereed proceedings of the two workshops held at the 14th International Conference on Principles and Practice of Multi-Agent Systems, PRIMA 2011, held in Wollongong, Australia, in November. The workshops were, Workshop on Agent Based Simulation for a Sustainable Society (ABSSS 2011) and International Workshop on Multi-Agent Smart Computing (MASmart 2011). The 8 papers presented were carefully reviewed and selected from various submissions. The papers cover topics from agent based simulation for a sustainable society and on multi-agent smart computing.

The volume aims at providing a comprehensive review of the diverse efforts covering the gap existing between the two main perspectives on the topic of ontologies for multi-agent systems. On the one hand, there is the knowledge modelling perspective; i.e. how ontologies should be modelled and represented in order to be effectively used in agent systems. On the other hand, there is the agent perspective; what kind of capabilities should be exhibited by an agent in order to make use of ontological knowledge and to perform efficient reasoning with it. Theory and experiences are emphasized as the volume collects the most significant papers of the AAMAS 2002 and AAMAS 2003 workshop on ontologies for agent systems, and the EKAW 2002 workshop on ontologies for multi-agent systems.

This book constitutes the thoroughly refereed post-conference proceedings of the International Workshop on Coordination, Organizations, Institutions, and Norms for Governance of Multi-Agent Systems, COIN 2017, co-located with AAMAS 2017, and the International Workshop on Coordination, Organizations, Institutions, Norms and Ethics for Governance of Multi-Agent Systems, COINE 2020, co-located with AAMAS 2020. The COIN 2017 workshop was held in Sao Paulo, Brazil, in May 2017 and the COINE 2020 workshop was held virtually, in May 2020. The 9 full papers and 1 short paper were carefully reviewed and selected from a total of 20 submissions for inclusion in this volume and cover the following topics: empirical applications of COINE technologies; emergence and social metrics; and conceptual frameworks and architectures.

This book constitutes the thoroughly refereed post-conference proceedings of the 12th International Workshops on Coordination, Organizations, Institutions and Norms in Agent Systems, COIN 2016. The workshop COIN@AAMAS 2016 was held in Singapore, Singapore, in May 2016, and the workshop COIN@ECAI 2016 was held in The Hague, The Netherlands, in August 2016. The 9 full papers were carefully reviewed and selected from 15 submissions for inclusion in this volume. They cover the following topics: Social Issues: The papers focus on the security of personal data, support for self-care for individuals with chronic conditions, analysis of the risk of information leakage in social networks, and an analysis of issues arising in the design of on-line environments whose participants are human and software. Teams: The papers consider different aspects of team working: what kinds of knowledge sharing best contribute to effective team performance and how to organize a tea m to function effectively in different kinds of scenarios. Rights and Values: The papers examine complementary issues that influence the effective design of normative systems, namely how to detect opportunism so that it may be discouraged, how individuals values influence (collective) decision-making processes and how rights and powers relate to value and conflict resolution in nested organizational structures.

This book constitutes the refereed proceedings of the 26th Australasian Joint Conference on Artificial Intelligence, AI 2013, held in Dunedin, New Zealand, in December 2013. The 35 revised full papers and 19 revised short papers presented were carefully reviewed and selected from 120 submissions. The papers are organized in topical sections as agents; AI applications; cognitive modelling; computer vision; constraint satisfaction, search and optimisation; evolutionary computation; game playing; knowledge representation and reasoning; machine learning and data mining; natural language processing and information retrieval; planning and scheduling.

This book constitutes the thoroughly reviewed joint post-conference proceedings of two international workshops on Coordination, Organization, Institutions and Norms in Agent Systems, COIN@AAMAS 2011, held in Taipei, Taiwan in May 2011 and COIN@WI-IAT 2011, held in Lyon, France in August 2011. The 12 revised full papers presented were carefully selected for presentations. The papers are organized in topical sections on agent coordination, norm-aware agent reasoning, as well as norm creation and enforcement.
