Detecting near-duplicates for automatically forming thematical text collections on the basis of web documents

Approaches to detecting near-duplicates appearing in thematic text collections accumulated automatically on the basis of text documents obtained from the Internet are discussed. The paper is focused on various modifications of shingle algorithm since it allows comparing a large number of texts quickly and without any preprocessing. The latter is particularly important when forming collections of raw texts.

Key Words
text collection, text comparing, shingle algorithm, near-duplicate, web documents, web resources
