摘要
决策树是归纳学习和数据挖掘的重要方法,该文对c4.5算法、决策树的构建和剪枝进行了介绍,然后将C4.5算法应用于信息检索结果分类中,实现了检索结果的分层分类处理。
Decision tree inductive learning and data mining is an important method.In this paper,c4.5 algorithm,decision tree construction and pruning were introduced.Then C4.5 algorithm is applied to the results of classification in information retrieval,search results to achieve a hierarchical classification.
