  • System and method for building knowledge-based applications
    Patent number: 5276775
    Abstract: A method and system (10) associates a deductive reasoning system having a forward deductive reasoning portion (13), a backward deductive reasoning portion (15), and a frame template portion (18) with a constraint satisfaction system (12) within a unified framework (11). The unified framework (11) incorporates a truth maintenance system to maintain dependency between premises, rules, and consequences in the deductive reasoning system (13, 15, and 18) and between initial constraints and propagated constraints in constraint satisfaction system (12). The system (10) treats constraints as declarative statements in order to maintain logical dependency under the truth maintenance system of unified framework (11).
