1. Motivation

• What are Bookmarks?
  • Personal repository of URLs, saved for re-visit

• Large repositories require structuring facilities:
  • Early browsers: flat list
  • Advanced browsers: directory tree, drag-and-drop GUI

• Manual URL organization is difficult
  • too many bookmarks to classify at once
    • Legacy, Import, Search results, Procrastination

  • lack of informativeness of title, URL
