Abstract

In this paper, on the basis of traditional TF-IDF algorithm, new and improved method is proposed. By adding the position weight coefficient and weight coefficients of word class, it can calculate the words which rely on high term frequency evenly. Experimental results showed that, the improved algorithm on the precision and recall rate are good, and it makes the selection of key collection reflect the document content orientation better.
