Abstract:

This paper presents a model of data mining based on the rough set theory, from applying various reductive level algorithms on practical data to elicit ing the information set of each level,and gets a rule set eventually. Conclusions are acquired on matching according to a certain algorithm when reasoning and making decisions. Finally, a simulated example on how to create and apply this model is given.
