The aim of the symposium was to provide an international forum for scientificresearch into the technologies and applications of agent and multi-agent systems.Agent and multi-agent systems are related to the modern software which has longbeen recognized as a promising technology for constructing autonomous, complexand intelligent systems. A key development in the field of agent and multi-agentsystems has been the specification of agent communication languages andformalization of ontologies. Agent communication languages are intended to providestandard declarative mechanisms for agents to communicate knowledge and makerequests of each other, whereas ontologies are intended for conceptualization of theknowledge domain.
