Five years ago, with excitement and uncertainty, we witnessed the birth of PRIMA (Paci?c Rim International Workshop on Multi-Agents). The ?rst PRIMA in 1998 has now grown into PRIMA 2003, the 6th Paci?c Rim Inter- tional Workshop on Multi-Agents in Seoul, Korea. During a period of ?ve years, the notion of agent research has grown so much that we hear the term agent on a daily basis. Various ?elds such as business, the Web, software engineering, on-line games and such are now using the term agent as a placeholder, just like the term object is used in the object-oriented paradigm. On the other hand, the research area has extended toward real applications, such as the Semantic Web and ubiquitous computing. The themes of PRIMA 2003 re?ected the following trends: agent-based electronic commerce, auctions and markets agent architectures and their applications agent communication languages, dialog and interaction protocols agent ontologies agent programming languages, frameworks and toolkits agentcities agents and grid computing agents and peer computing agentsandtheSemanticWeb agents and Web services arti?cial social systems con?ict resolution and negotiation evaluation of multi-agent systems languages and techniques for describing (multi-)agent systems meta modeling and meta reasoning multi-agent planning and learning multi-agent systems and their applications social reasoning, agent modeling, and organization standards for agents and multi-agent systems teams and coalitions ubiquitous agents
