Abstract

Abstract: A method of improved feature extraction based on synonymous was proposed. The method collected synonyms in the text as a set, adjustment the weights of synonyms in the set and related words based on TF-IDF,and combined synonyms through the similarity.The experimental results display that the new method improves the accuracy of feature extraction.

Key words: feature extraction, TF-IDF, synonymous, hownet, co-occurrence
