Abstract
Systems and methods are disclosed for performing duplicate document analyses to identify texturally identical or similar documents, which may be electronic documents stored within an electronic discovery platform. A process is described which includes representing each of the documents, including a target document, as a relatively large n-tuple vector and also as a relatively small m-tuple vector, performing a series of one-dimensional searches on the set of m-tuple vectors to identify a set of documents which are near-duplicates to the target document, and then filtering the near set of near duplicate documents based upon the distance of their n-tuple vectors from that of the target document.
