Abstract:
A ripple down rules knowledge based system for generating an output conclusion in response to an input case, said system including a database arranged to receive and store a plurality of conclusions and a plurality of rules, each new conclusion added to the database being associated with a previously stored conclusion as a refinement of the previously stored conclusion and each new conclusion added to the database being associated with a rule, input means for facilitating input of a case, and output means for outputting at least one previously stored conclusion in response to the input case, said system being arranged such that when multiple identical conclusions are returned by the system in response to an input case and a new conclusion associated with the input case is added as a refinement of said identical conclusions, a list of cornerstone conflict cases associated with all of said identical conclusions is generated, and said system being arranged to receive an input rule indicative of a difference between the input case and the cornerstone conflict cases, and to associate the input rule with each of said identical conclusions.
