Based On Decision Tree Classification Algorithm

With the extensive application of Data Warehouse, it's more and more important to get correlative knowledge or rule from data, so there are all kinds of technologies about Data Mining (DM) to be put forward in the latest decades in order to solve this problem. This paper introduces some knowledge and algorithm about DM in details at first, then expatiating the classifying based on decision tree, especially explaining the ID3 algorithm and it's extended algorithm-C5.0; at the same time importing the classified algorithm based on attribute to be compared with the decision tree; At last, there is a realization that making use of C5.0 to classify the vehicle administration in the Logistics decision-making system.
