Application of Quotient Space Theory in Cases Organization

People who are not familiar with data mining algorithms canpsilat use general data mining systems, because these data mining systems must rely on experts to give the algorithm to operate data mining. To make more people can use data mining systems conveniently; data mining system based on Case Based Reasoning was put forward in the paper. In this system, cases were organized under fuzzy quotient space model instead of traditional case index tree. Quotient space theory can divide orient universe into different grain size world, when retrieving case, it doesnpsilat need to compare with all the cases in case base like index tree, which can improve retrieval efficiency and accurate rate. Experiment indicates the average effect was improved by 51.81 percent; it will become higher if the case base becomes bigger.
