| Abstract: | Reprinting websites and blogs produces a great deal redundant WebPages.To improve search efficiency and user satisfaction,the near-Duplicate WebPages Detection based on Concept and Semantic network(DWDCS) is proposed.In the course of developing a near-duplicate detection system for a multi-billion pages repository,this paper makes two research contributions.First,the key concept is extracted,instead of the keyphrase,to build Small Word Network(SWN).This not only reduces the complexity of the semantic networ... |
