<p>System and method for facilitating exchange on a computer network, such as the Internet. The system provides one or more context trees (11), with each tree (11) including two or more connected nodes (17), each node (17) being associated with one or more node objects (19). Associated with each node (17) is a blackboard for receiving and making available for reading, messages concerning the node object, a knowledge base containing information, facts, constraints and/or rules ('Rules') concerning the node object, and an inference engine providing at least one logical rule that can be used to infer a logical conclusion based on at least one Rule in the knowledge base. A tree (11) has a collection of at least two mobile intelligent agents (13) that are configured to facilitate exchange of information on a node object, between two agents or between a node and an agent (13). An agent (13) may migrate from a first node to a second node connected to the first node. An agent, by subscribing to the Rule of a node, is permitted to post a message on, and to read a message posted on, a blackboard for the subscribed node. The collection of agents has at least one tree agent that has knowledge of nodes that are directly connected to each node in the tree.</p> |
