The paper introduces a balanced coefficient to improve the veracity of C4.5 algorithm. It can be fixed by decision maker according to priori intellectual and domain intellectual. It harmonized the information gain-ratio of each attributes artificially in specific environment. The classification is more veracious and rational by the decision tree made from the improved algorithm. And compared the improved algorithm to C4.5 algorithm by analyzing examples, to prove the efficiency of the improved algorithm.
