摘要

PROBLEM TO BE SOLVED: To find out a proper mirror site group and to enhance the processing efficiency. SOLUTION: A page which forms a top page of a Web site is estimated from a large Web page group (S1), a site group is determined from the top page estimated for the Web page group and a page linked thereto (S2), and sites having a size of a fixed value or more of the site group are selected as a processing object (S3). A file of site characteristic elements (information for link character strings, anchor character strings and internal/external links possessed by the sites) is formed (S4). Site pairs having the same characteristic element are selected as mirror site candidates (S5), and a mirror site pair is detected from the similarity of the mirror site candidate pairs (S6).
