为了提高归结方法处理带有不可比较性信息的能力,给出了四值格值命题逻辑系统上的语义归结原理,并证明了其可靠性和完备性,其上归结原理的研究为归结算法的实现提供了理论基础,从而为处理含有不可比真值的格值逻辑系统在智能推理系统中的实际应用提供了有力的支持。
For improving the efficiency of dealing with information with incomparability through resolution method,this paper investigated the semantic resolution method based on four-elements non-chain lattice-valued propositional logicis system L4P(X) and proved soundness theorem and completeness theorem of this resolution method.Resolution based on L4P(X)would be the theoretical foundation of resolution algorithm.Accordingly,this paper provided some supports for the application of intelligent reasoning system including incomparable elements based on lattice-valued logic.
