| Abstract: | Based on the theory of granular computing and from the viewpoint of information granularity , Knowledge-granular base in ordered information systems is defined in the paper .After studying its several proper-ties, this paper proposes the close-degree of knowledge-granular base, which is used to transform the problem of how to measure the similarity of knowledge into the problem of operations between granules in ordered information systems.Finally, an attribute reduction algorithm without core based on knowledge-granular base is presented , and this method is proved to be effective . |
