Improvement and Application of TF * IDF Algorithm

  • Conference paper

Part of the book series: Lecture Notes in Computer Science ((LNISA,volume 7030))

Abstract

The traditional TF-IDF probability model is a relatively simple formula. For a few words which are commonly used and not stop words in a paper,it is lack of better differentiate and is not suitable for many specific cases, such as news advertising service module, about extraction of key words of the article, according to the deficiencies and the demand of news advertising service module, on the basis of the original algorithm, presents a new probability model——MTF-IDF, it greatly improves the accuracy of news information data retrieval.
