I have 1000 unsorted, untagged bookmarks that I want to upload to a service and have it automatically and intelligently tag all of the bookmarks by the category they best fit with. I could then adjust it later. But it seems the bookmark services just suggest tags. Does any bookmark fully automate everything from one upload? I looked at Xmarks.com, Delicious.com, Diigo.com and Springpad.com, but didn't notice this ability.  Update: Delicious can tag bookmarks, but only of sites that have already been tagged by its users. Is there any service that uses more extensive data to get more accurate tagging? 
Is there any bookmarking service that can automatically sort all my bookmarks?
