Social Bookmarking Social Bookmarking Presentation Transcript

  • SOCIAL BOOKMARKING BY: Phaneendra K Kolli.
  • INTRODUCTION
    • It is a method for Internet users to store, organize, search, and manage bookmarks of web pages on the Internet .
    • These bookmarks are usually public, and can be saved privately, shared only with specified people or groups.
    • Most social bookmark services encourage users to organize their bookmarks with informal tags .
  • HISTORY
    • The concept of shared online bookmarks dates back to April 1996 .
    • They provided folders for organizing bookmarks, and some services automatically sorted bookmarks into folders .
    • Some included browser buttons for saving bookmarks and enabled users to email their bookmarks to others .
  • SOCIAL BOOKMARKING SITES
    • del.icio.us
    • Digg
    • StumbleUpon
  • Del.icio.us
    • Del.icio.us uses a non-hierarchical keyword categorization system in which users can tag each of their bookmarks with a number of freely chosen keywords .
    • Del.icio.us has a "hotlist" on its home page and "popular" and "recent" pages, which help to make the website a conveyor of internet memes and trends.
    • All bookmarks posted to Del.icio.us are publicly viewable by default, although users can mark specific bookmarks as private .
  • Digg
    • Digg combines social bookmarking, blogging, and syndication with a form of non-hierarchical, democratic editorial control.
    • News stories and websites are submitted by users, and then promoted to the front page through a user-based ranking system.
    • Once a story has received enough "diggs", it appears on Digg's front page.
  • Stumbleupon.
    • StumbleUpon is a web browser plugin that allows its users to discover and rate webpages .
    • StumbleUpon chooses which new webpage to display based on the user's ratings of previous pages .
    • Users can rate, or choose not to rate, any webpage with a thumbs up or thumbs down, and clicking the Stumble button .
  • Advantages
    • For users, social bookmarking can be useful as a way to access a consolidated set of bookmarks from various computers, organize large numbers of bookmarks, and share bookmarks with contacts.
    • All classification of Internet resources is done by human beings, who understand the content of the resource.
    • Getting resources from others in our discipline.
  • Disadvantages
    • Mistagging due to spelling errors and tags that can have more than one meaning .
    • Social bookmarking can also be susceptible to corruption and collusion.
    • Spammers have started bookmarking the same web page multiple times and/or tagging each page of their web site using a lot of popular tags, obliging developers to constantly adjust their security system to overcome abuses.
