The lattice-valued Turing machines and the lattice-valued type 0 grammars
Summary: \textit{Purpose.} The purpose of this paper is to study a class of the natural languages called the lattice-valued phrase structure languages, which can be generated by the lattice-valued type 0 grammars and recognized by the lattice-valued Turing machines. \textit{Design/Methodology/Approach.} From the characteristic of natural language, this paper puts forward a new concept of the l-valued Turing machine. It can be used to characterize recognition, natural language processing, and dynamic characteristics. \textit{Findings.} The mechanisms of both the generation of grammars for the lattice-valued type 0 grammar and the dynamic transformation of the lattice-valued Turing machines were given. \textit{Originality/Value.} This paper gives a new approach to study a class of natural languages by using lattice-valued logic theory.
