信息系统中的知识距离与知识粗糙熵

Knowledge Distance and Rough Entropy in Information Systems

本文基于知识即划分的观点,证明了论域中所有知识构成一个距离空间,研究了知识距离空间中知识距离的一些性质,并应用知识距离度量信息系统中知识的粗糙熵。这些结果有利于更加深刻地分析信息系统中知识间的关系和知识的粗糙性。

In the present paper, based on the view of knowledge induced by partition, all knowledge in the universe constructs a metric space, and the properties of knowledge distance are studied. Moreover, the knowledge distance is used to measure rough entropy of knowledge. These results will be very helpful for analyzing the relationships among knowledge and the roughness of knowledge thoroughly in information systems.
