| 中文摘要: |
| 概念格是知识表现的有力工具,在概念格基础上,利用构造方法,首先探讨概念知识系统上两个算子之间的关系。指出这两者之间可以相互导出,由此给出了概念知识系统的等价刻画,文中最后探讨两个概念知识系统的关系。 |
| 英文摘要: |
| 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. |
