Abstract :
Service-oriented architectures enable services to be dynamically selected and integrated at runtime, thus enabling system flexibility and adaptiveness - autonomic attributes that are key for modern business needs. However, current techniques provide no support for actually making rational selections, which are key to accomplishing autonomic behavior. We develop a multiagent framework based on an ontology for QoS and a new model of trust. The agents form an ecosystem in which they help each other select services best matching their preferences. We evaluate by simulation the agents´ effectiveness in maintaining self-adjusting trust
