An apparatus and method for an expert knowledge system developmental tool 50 comprising a computer 52 with a structure for storing a knowledge base 54 and an inference engine 56 for inferring from the knowledge base 54. The knowledge base 54 defines a plurality of positive and negative rules 402,410, each rule having one or more antecedents 302 and one conclusion 328. The interference engine 56 includes structure 100 for storing a hypothesis list and structure 100 for selecting rules that have a conclusion which match each hypothesis and the negative of each hypothesis. Further, the inference engine 56 includes structure 116-150 for analyzing the selected rules 402, 410 with respect to each other in order to determine a value of each hypothesis, and structure 162-184 for analyzing the antecedent 302 of each rule to determine a value for each rule 402, 410.

An expert knowledge system development tool comprising a computer with means for storing a knowledge base and inference engine means for inferencing with respect to at least one hypothesis variable from said knowledge base storing means comprising: said knowledge base storing means including: means for defining a plurality of positive and negative rules wherein said rules defining means includes: (a) means for defining at least an antecedent variable for each of said rules and means for defining a conclusion variable for each of said rules; and said inference engine means including: (a) means for storing a hypothesis variable list containing said at least one hypothesis variable; (b) means for automatically selecting and ordering said rules stored in said knowledge base storing means to establish the structures of said rules into a rule tree by determining if any conclusion variable is also an antecedent variable; (c) means for selecting and sorting said rules ordered in said rule tree that have conclusion variables which match each hypothesis variable into one bundle and said rules that have conclusion variables which match the negative of each hypothesis variable into another bundle; and (d) means for analyzing the selected said rules with respect to one another for each bundle separately in order to determine a value for each hypothesis variable.
