....of duplicates and near duplicates has been estimated at 30 to 45 [1, 8] The principal reason for duplication on the Web is the systematic replication of content across distinct hosts, a phenomenon known as mirroring. It is estimated that at least 10 of the hosts on the WWW are mirrored [2, 4]. Duplication has both positive and negative aspects. On one hand the redundancy makes retrieval easier: if a search engine has missed one copy, maybe it has the other; or if one page has become unavailable, maybe a replica can be retrieved. On the other hand, from the point of view of search ....

....to a query is a nuisance. The principal reason for duplication on the Web is the systematic replication of content across distinct hosts, a phenomenon known as mirroring (These notions are defined more precisely below. It is estimated that at least 10 of the hosts on the WWW are mirrored [2, 12]. The aim of this paper is to present and evaluate algorithms for detecting mirroring on the WWW in an information retrieval framework. We start with some definitions. Each document on the WWW has a unique name called the Universal Resource Locator (URL) The URL consists of three disjoint parts, ....
