Abstract
A method for document similarity analysis. The method includes obtaining a document to be archived, obtaining indexing terms for the document to be archived, and identifying document categories similar to the document to be archived, based on indexing terms and corresponding term frequencies. The method further includes making a determination that a weakly similar document category exists and based on the determination: generating a new document category and registering the document in the new document category, and registering the document in the weakly similar document category.
