Abstract
Reliable identification of highly similar documents allows such documents to be treated as identical for purposes of document analysis. Identification of highly similar documents can be based on a composite hash value or other value for which the likelihood of two documents having the same value is high if and only if the documents have a high degree of similarity. Prior to performing content based analysis, the composite hash value for the current document is determined and compared to composite hash values of previously analyzed documents. If a match is found, the results of the analysis of the previous document can be applied to the current document. If no match is found, the current document is analyzed.
