  2. 2. INTRODUCTION <ul><li>It is a method for Internet users to store, organize, search, and manage bookmarks of web pages on the Internet . </li></ul><ul><li>These bookmarks are usually public, and can be saved privately, shared only with specified people or groups. </li></ul><ul><li>Most social bookmark services encourage users to organize their bookmarks with informal tags . </li></ul>
