 In order to resolve the disadvantages of traditional TFIDF in text filtering, the authors propose a text information filtering algorithm based on feature extraction. This paper briefly analyses the text information filtering principles and processes, and then focuses on the design and realization of information filtering algorithm. Experimental results show that the new approach significantly outperforms the traditional information filtering method.

Key wordsInformation extraction      Information filtering      Text feature extraction      TF-IDF
