Abstract :
In this paper, we combine the concept of natural deduction and the concept of three-valued natural logic. In particular, we use a semantic definition of the concept of natural logic presented by N. Tomova. By using the correspondence analysis given by B. Kooi and A. Tamminga, we present a syntactical counterpart of the semantic definition in question, i.e. in this paper, three-valued natural logics are characterised by natural deduction systems.
