Abstract
The development of the internet and exponential growth of network information produce a large number of duplicated pages on the network, reducing the retrieval of recall and precision and affecting the retrieval efficiency. The accuracy of the web, therefore, influences the quality of search engine. On the basis of the structural text description, this paper proposes an improved eliminating repetitive algorithm method, which is based on MD5 of Near-replicas. It proves that the method has a good effect on improving the recall and the precision through experiment.
