This article improves the algorithm of term weighting in automated text classification. The traditional TFIDF algorithm is a common method that is used to measure term weighting in text classification However, the algorithm does not take the distribution of terms in inter-class. In order to solve the problem, variance which describes the distribution of terms in inter-class and intra-class is used to revise TFIDF algorithm. This article mainly researched about the construction of LFHW term sets and new approaches to term weighting, These new approaches are also applied to the hierarchical classification system Compared with traditional TFIDF algorithm the results of simulation experiment have demonstrated that the improved TFIDF algorithm can get better classification results
