Multi-agent programming system on a workstation network

We propose a multi-agent programming system based on Prolog. In this system, a new concept called "field" is introduced. A field provides a knowledge base which is written in a form of Prolog program. An agent can "enter" into or "exit" from a field. Multiple agents can enter into one field, and the knowledge base of the field is shared by the agents. Therefore, agents in a field can communicate each other through the field. It is also possible for the agent to enter into multiple fields. A prototype programming system based on this model was built on a workstation network.
