AT9-86-007 ABSTRACT A method for use in an expert system which selectively allows the system to avoid asking the user a question by providing the answer to that question based on related information that may have been previously attained in the system. 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 Dodes in she 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.
