摘要
采用数据挖掘技术中的决策树方法,进行收视数据分析.收集大量的调查问卷作为待挖掘的样本,利用决策树经典算法C4.5,对样本集中的样本进行学习,构造出一棵决策树.对决策树进行分析,得出电视收视分析相关的知识和规律,作为节目编制等的决策依据.
This thesis uses decision tree to analyze data for TV Station.Firstly a questionnaire is designed to allow the audiences to fill out and the surveys are the samples which are to be excavated.This thesis makes use of classical decision tree algorithm-C4.5,and constructs a decision tree from the sample set.By analyzing of the decision tree,the factors which can influence the TV ratings are got,and make programs reasonably.
