Abstract
A method for efficiently grouping electronic documents that are likely textual near-duplicates includes processing first and second electronic documents to determine respective sets of character sequence counts. The processing includes, for each document, (1) identifying non-contiguous character sequences expressed within the document text, with each character sequence corresponding to a different starting position within the text and including at least a first character at the respective starting position and a second character at a pre-defined offset from the respective starting position, and (2) determining character sequence counts for each unique character sequence within the identified character sequences. The method also includes generating one or more similarity metrics, at least by comparing the sets of character sequence counts determined for the first and second electronic documents. The method may also include assigning, based on the similarity metric(s), the second electronic document to a same document group as the first electronic document.
