| Abstract: | Concept lattice is a useful tool of knowledge representation.In this paper,we discuss the relations between the two operators of the concept knowledge systems based on the construction method.It is shown that the two operators can be determining by each other.Furthermore,the equivalent characteristics of the concept knowledge system are given.Finally,the relations between two concept knowledge systems are discussed. |
