Much research has been done on intelligent agent knowledge sharing through the use of common, pre-defined ontologies. However, several domains, including the World Wide Web, often precipitate intelligent agents selfishly inventing ontologies based on their utility for the task at hand. If such agents are able and willing to teach each other semantic concepts based on their individual ontologies, then the entire group of agents can accomplish their group and individual tasks more efficiently and effectively. We present our prototype DOGGIE (Distributed Ontology Gathering Group Integration Environment) which demonstrates how a group of agents with diverse Web ontologies can learn the location and translation of semantic concepts.
