ABSTRACT:
A system, method and computer program product for identifying near and exact-duplicate documents in a document collection, including for each document in the collection, reading textual content from the document; filtering the textual content based on user settings; determining N most frequent words from the filtered textual content of the document; performing a quorum search of the N most frequent words in the document with a threshold M; and sorting results from the quorum search based on relevancy. Based on the values of N and M near and exact-duplicate documents are identified in the document collection.
