This paper presents a theoretical framework of nave fuzzy description logic which mainly includes the construction of nave membership function and the nave reasoning based on fuzzy description logic.The basic idea of construction of nave membership function is to simplify the values of membership in fuzzy sets,and fuzzy sets are considered in two ways,i.e.,their membership function refers to the degree of either the set membership or the symbolic index of the aggregation of elements.Besides,if problems need to be deepened,we improve the fuzzy set using the concept of type 2 or level 2 fuzzy sets in fuzzy set theory,and then transform it back to the ordinary fuzzy set.In this way we extend grades of membership in fuzzy sets and(or) come up with a new fuzzy set.In terms of nave reasoning,we use all operators in fuzzy set theory but do not emphasize their consistency in logic.Finally taking traditional Chinese medicine as an example,this paper illustrates that the nave fuzzy description logic plays an important role in expressing empirical theory which is different from Western scientific paradigm.
