Study on the Improvement of TFIDF Algorithm in Data Mining

Abstract

In order to remedy the defects of traditional methods in the data mining, improving the data mining effect. The paper proposed the improved TFIDF algorithm and applied to the data mining based on the analysis of the flaw and the insufficiency in simple calculation method, minimum value calculation method and the traditional TFIDF algorithm. The paper proved that the improved TFIDF algorithm is better than other traditional methods more scientific, more advantages and practical value based on four data mining results are compared and evaluated.
