Rules Extracting Based On Data Mining Technology

Automation and intelligentization are the main goals of developing remote sensing and GIS. During the course of the development, this issue was faced with many difficulties and challenges, especially the need of real-time and dynamic analysis with great data. And now there is not a really model in self-motion discovery with semantic information. People cry for the effective, automatic and intelligent methods to analyze the great number of data and discover the information that people are interested in. In recent years, it has been a focus for some people to analyze the abundant, complicated and comprehensive data and discover the ruleOn the basis of the analysis above, the author investigated a new method in data mining in this thesis. In this thesis, the author first presented the background knowledge and thedevelopment about a new developing discipline—data mining(DM)and knowledgediscovery database(KDD),then the author generalized a great deal of methods about data mining. Among them, the author put an emphasis on the introduction of two theories about the method of data mining—rough set theory and cloud theory. Through contrast study, the author discovered that the two theories are interdependent and can be used together. Secondly, the paper offered an effective and plansible method in Data mining with the combination between Rough set theory and Cloud theory. That is, the basis data was pretreated by Cloud theory, the reduction data was obtained by Rough set theory, and the sort of decision-making in the knowledge was discovered, got the decision-making list. Finally, the indefinite method of Cloud theory was applied to the knowledge to express and deliver the indefinition of the knowledge and reasoning. This method can transform the qualitative data and quantitative data effectively, enhance the insight into knowledge discovery.Finally, the author analyzed the activity intensity of geofracture in XI'AN through this method, and obtained the subarea about the activity intensity of geofracture and extracted regulation extraction through Cloud theory. The result is basically corresponding with the reality, and t can be used by the expert as the foundation in making decisions.
