Based on analysis of the classic algorithm of eliminating the duplicates, his article raises an improved algorithm for judging web page text repetition. The new algorithm runs the elimination process on the basis of webpage contents which are used as the vector characteristics in the comparison with the webpages´ approximation, and analyzes how to capture the web page´s theme.
