• Abstract:Abstract Feature weighting algorithm is a key step in feature extraction. In this paper，according to two classifications situation of web page theme, we improved the traditional feature item weighting method of TF-IDF. On the basis of this, We give a new linear feature weighting algorithm based on the feature’s position information and the information it contained. Experimental results show that this algorithm has higher the theme web page recall rate and precision rate than the traditional method TF-IDF in the theme web page filtering.
