Abstract
A computer-implemented method is disclosed. The method includes obtaining a candidate pair of a plurality of digitally stored documents from a document database. The method automatically computes relative positional differences between each digitally stored document of the candidate pair. The method compares the relative positional differences with a similarity function to form a difference similarity vector for the candidate pair. The difference similarity vector includes components corresponding to each relative positional difference. The method aggregates the components of the difference similarity vector to determine a final score for the candidate pair. The method determines a document-level similarity metric from the final score. The method determines whether the document-level similarity metric is above a threshold value and then classifies the candidate pair based on determining that the document-level similarity metric is above the threshold value to de-duplicate the plurality of digitally stored documents in the candidate pair.
