The method involves providing an action attribute that can be attached to any node in the rule tree. The attribute is assigned to a node in the tree which provides an answer to a class question based on processing various other dependent nodes. When the answer is obtained, the action attribute then causes all other nodes in the rule base referencing the same class question to be set to the same answer. The user is therefore only requested to supply information as a last resort.Other References
