This volume contains papers selected for presentation at the 1st KES Symposium onAgent and Multi-Agent Systems – Technologies and Applications (KES-AMSTA2007), held in Wroclaw, Poland, May 31 – June 1, 2007. The symposium was organizedby the Institute of Information Science and Engineering, Wroclaw University ofTechnology, and KES International, as part of the KES Conference Series.The aim of the symposium was to provide an international forum for scientific researchin the technologies and applications of agent and multi-agent systems. Agentsand multi-agent systems are related to the modern software which has long been recognizedas a promising technology for constructing autonomous, complex and intelligentsystems. A key development in the field of agent and multi-agent systems hasbeen the specification of agent communication languages and formalization of ontologies.Agent communication languages are intended to provide standard declarativemechanisms for agents to communicate knowledge and make requests of eachother, whereas ontologies are intended for conceptualization of the knowledge domain.
