【Abstract】 In recent years, with the search engine technology and the network data mining technology development, how to find the useful information from the search engine query log becomes an important research direction. This paper discusses the excellences and the disadvantages of the clustering algorithm proposed by Beeferman and the improved algorithm which is proposed by Chan. A new improved algorithm based on the user profile of the Webpage is proposed that can weaken the influence of the noises data. And the simulation experiment proves that the new algorithm is better than the Beeferman algorithm and the Chan algorithm.更多还原
