Abstract: his paper puts forward the concepts of one direction variation S-knowledge, granulation degree and filter degree of one direction variation S-knowledge. Using these concepts, we further discuss the characters of granulation degree and filter degree about one direction variation S-knowledge. In the end , this paper presents the first mining principle and filter principle about one direction variation S-knowledge.

Key words: Variation S-rough sets, Elementary transfer, One direction variation S-knowledge, Granulation degree of one direction variation S-knowledge, Filter degree of one direction variation S-knowledge
