Abstract: Linguistic-values-based intelligent information processing is one of the most important research directions in artificial intelligence,and resolution-based automated reasoning has been extensively studied because of its easy implement on computer.For improving the efficiency of α-resolution principle in linguistic truth-valued lattice-valued logic,we applied the semantic resolution strategy to α-resolution and investigated the resolution-based automated reasoning methodin lattice-valued logic.Firstly,the equivalence of α-semantic resolution in linguistic truth-valued lattice-valued propositional logic LV(n×2)P(X) and the α-semantic resolution in corresponding resolution level for LnP(X) was given,and the effectiveness of α-semantic resolution method was illustrated through an example.Subsequently,the semantic resolution algorithm for this resolution was investigated,and sound theorem and weak complete theorem of this semantic resolution method were proved.
