Abstract: The ability to share knowledge is a necessity for agents in order to achieve both group and individual goals. To grant this ability many researchers have assumed to not only establish a common language among agents but a complete common understanding of all the concepts the agents communicate about. But these assumptions are often too strong or unrealistic. In this paper we present a comprehensive study of performance of agents learning ontology concepts from peer agents. Our methodology allows agents that are not sharing a common ontology to establish common grounds on concepts known only to some of them, when these common grounds are needed by learning the concepts. Although the concepts learned by an agent are only compromises among the views of the other agents, the method nevertheless enhances the autonomy of agents using it substantially. The experimental evaluation shows that the learner agent performs better than or close to teacher agents when it is tested against the obj ects from the whole world. (More)
