Abstract
Introduces the SIMS system, an information mediator that provides access to heterogeneous data and knowledge bases by acting as a single information agent that can be instantiated to provide multiple agents. Considers critical aspects of any agent-based system: agent organization, knowledge of an agent, communication language and protocol, query processing and learning capabilities. Outlines features of the SIMS approach
