Research On Special Subject Mining Of News In News Database Based On CNML

With the rapid development of journalism in China, it has become a developmental direction that news information resources of efficiently organized and increasingly rich management, and active expansion of the application of news technology. The research on special subject mining of news in news database which is based on CNML just makes use of the data mining technology, promoting the development of news intelligence and making actively exploration of the new model of news production. The paper focuses on the making process of special subject in press area, making analysis and research on the news database system based on CNML through data mining technology, and building the fundamental mining process model. Besides, through corresponding algorithm analysis, it clearly shows the basic process of intelligent production of news special subject through examples, and obtaining concrete research achievements: design and practise a set of practical method of special subject production based on CNML news database; explore successfully the way of using mathematical model(AHP) to evaluate news information efficiently.
