【Abstract】 In this paper, the page block based Web archive collecting and storing approach is proposed. The algorithms of layout-based page partition, extracting topic from block, version comparison and incremental storage implementation are introduced in detail. The prototype system is implemented and tested to verify the proposed approach. Theoretics and experiments show that, the proposed approach adapts the Web archive management well, and provides a valuable data resource to the Web archive based query, search, data mining and knowledge discovering applications.更多还原
