abstract:this paper investigated data mining through combining global model constructing and local pattern mining, especially studied global data mining based on local information. on the basis of the process of data mining,it divided this problem into three phases, including improving the efficiency of mining using granular representation, improving the interpretation of local mining using global model, improving the efficiency and accuracy of global mining. and the paper reviewed these three problems respectively. finally, the paper summarized and also pointed out some future works.......
