Intelligent data mining method and system based on big data

The invention provides an intelligent data mining method and system based on big data, and the method comprises the steps: selecting theme keywords in an existing big database, and carrying out the permutation and combination of the keywords to construct a keyword screening channel; screening and separating the big data through a keyword screening channel to obtain a mining database conforming to the keyword channel; performing data preprocessing on the mining database to obtain mining data with concentrated density; and performing linear regression calculation on the mining data with concentrated density through keywords and other high-frequency words to obtain a data mining result, so as to solve the problem that the data mining accuracy and efficiency are reduced due to excessive data volume in a big data environment, and solve the problem that the data mining is limited by themes and fields. 本发明提出了一种基于大数据的智能数据挖掘方法及系统，在现有的大数据库中选择主题关键词，将关键词进行排列组合构建关键词筛选通道；将大数据通过关键词筛选通道进行筛选分离，获取符合关键词通道的挖掘数据库；对挖掘数据库进行数据预处理，获取
