A DOCUMENT CACHE REPLACEMENT POLICY FOR AUTOMATICALLY GENERATING GROUPS OF DOCUMENT BASED ON SIMILARITY OF CONTENT

A document storage management system and method that manages the storage of documents based upon the similarity of the content of the documents. Groups of documents are created based upon the similarity of the contents of the documents. Those groups are displayed to the user in a ranked list of selectable groups to permit selection of a group or document. The storage of the selected group or document is then managed by, for example, deleting, compressing, or copying. The displayed list may be ranked based upon a least recently used policy, the relevance to a predetermined topic, the size of the group, the radius of the group based upon the maximum distance of any document from the group centroid, the number of documents in the group and any other combination of parameters.
