  • - Most pages that are bookmarked have been modified between 1 and 100 days
  • Clockwise starting in upper left-hand corner: RSS (Really Simple Syndication);Technorati; Twitter;
  • Public (3) Social bookmarking websites are more user-friendly and popular than NIAID, thus making it a comfortable venue for exploration Both (1) Tagging is done by human beings, who understand the content; as opposed to software which algorithmically attempts to determine meaning Private (1) Can rank a resource based on how many times it has been bookmarked by users, which may be a more useful metric b/c (a) it shows popularity (b) bookmarking is a purposeful action, so accidental clicking is reduced
  • Both (1) no standard set of keywords (i.e. no controlled vocabulary), no standard for the structure of tags (e.g., singular vs. plural, capitalization, etc.), spelling errors, tags that could have more than one meaning, synonym/antonym confusion, unorthodox and personalized tag schemata from some users ,Acronyms present ambiguity ,here is no synonym control in the system; tags have seemingly have similar intended meanings ( Eg. “mac,” “macintosh,” and “apple” all being used to describe materials related to Apple Macintosh computers) (2) eg. a site might be labeled as both cheese and cheddar, with no mechanism that might indicate that cheddar is a sub-class of cheese Private (1) Traditionally, OCGR has used a hierarchy; also, it will be harder to “reorganize” data
  • - A network bundle is a way to organize friends

Social bookmarking Social bookmarking Presentation Transcript

  • Embracing Web 2.0: Social Bookmarking A study by Ida Rosenthal Source: http://www.frontiernet.net/
  • The Web 2.0 Movement
    • Web 2.0 is the second generation of web development and web design with a focus on:
        • communication
        • information sharing
        • collaboration
        • user-centered design
        • two-way interactions
  • What is Social Bookmarking (SB)?
    • SB is a method for users to store , organize , and search , bookmarks of web pages on the Internet
        • Most social bookmarking services allow users to organize bookmarks with informal metadata, usually called tags
  • What kind of info can we find?
    • Social bookmarking URLs are full of new and fresh information
    • Delicious has little redundancy in page info for ~50% of URLs and high redundancy for ~20%
    • Tags are pretty accurate
        • % of Tags Users Found Irrelevant:  7%
        • % of Tags Users Found Subjective:  <5%
  • Who ’s Who in Social Bookmarking Digg.com Considered the #1 SB website 1 1 &quot;Top 20 Social Bookmarking Sites| June 2009.&quot; The eBusiness Knowledgebase . June 2009. EBizMBA. 15 June 2009 < http://www.ebizMBA.com/articles/social-bookmarking >. 2 Arrington, Michael. &quot;Feature Overview of Delicious 2.0.&quot; TechCrunch . Sept. 2007. 16 June 2009 <http://www.techcrunch.com/2007/09/06/exclusive-screen-shots-and-featureoverview-of delicious-20-preview/>. 3 The eBusiness Knowledgebase Flickr.com Primarily hosts image and video content Delicious.com Has more than five million users and 150 million bookmarked URLs 2 ; it ’s the 6 th most popular SB website. 3 Stumbleupon.com Personalized recommendation engine; “channel-surfing” Reddit.com Like Digg, allows users to rank links, causing them to become more/less popular Diigo.com Allows users to highlight web pages, attach sticky notes & share annotations
  • The Tragedy of Ma.gnolia
    • Ma.gnolia.com was a popular SB website that launched in 2006
        • Largest rival to Digg and Delicious
    • Owners maintained the hosting themselves
    • Lost half a terabyte of data
        • Lost most primary files and backup too
        • Data corruption
    • closed early 2009 w/ plans to reopen late 2009
  • Advantages Public Both Private (w/n OCGR) 1. Ppl can find & bookmark web pages that haven ’t been noticed by automated computer programs 1. More intuitive ( “human touch”) 1. Information gathered from rankings  useful web metric 2. allows for exploration and more browsing 2. automatically generates “related” tags 2. Consolidates bookmarks from various computers and share bookmarks with contacts 3. Makes users more comfortable with content 3. allows users to quickly share news about events in real time 3. search engines will discover the link to the page each time it is posted at one of the social bookmarking sites
  • Disadvantages Public Both Private (w/n OCGR) (1) spammers have started bookmarking the same web page multiple times a lot of (unrelated) popular tags (1) mistagging errors can be extensive (1) no mechanism to indicate hierarchical relationships between tags (2) SB can be distracting and confusing (2) no mechanism to indicate hierarchical relationships between tags (2) Catch-22: You cannot get the links if people can't find you, and people can't find you without the links.
  • What Isn ’t Gonna Work?
    • Some SB sites don ’t meet OCGR’s needs on a public or private level:
    • examines technology-related topics
    • similar design to Digg, but not as user-friendly
    • “ channel-surfing”
    • more for entertainment and random discovery
    • does not support articles or documents
    • exclusively photographs and images
  • Let ’s “Digg” In!
    • Cornerstone function: Voting stories up and down
      • “ digging” and “burying”, respectively
      • Very user-friendly  most popular SB website
    • only the most “Dugg” stories appear on the front page
    • Allows user to easily identify information as an article, video, or picture
    • No tags
    • Allows for the user to add friends to a network
      • Cannot organize friends into smaller clusters
      • Difficult to organize personal bookmarks
  • It ’s Delicious (.com)!
    • Previously known as del.icio.us
      • five million users & 150 M bookmarked URLs
    • has a &quot;hotlist&quot; on its home page
      • additional &quot;popular&quot; and &quot;recent&quot; pages help make the site a conveyor of internet trends
    • Allows for the user to add friends to a network; also allows network bundles (smaller groups)
    • Allows “tag bundles” to organize a group of tags
      • Eg. &quot;cats&quot;, &quot;dogs&quot; and &quot;fish&quot; tags may all be put into a bundle called &quot;pets ”
    • &quot;Diigo&quot; is an abbreviation for &quot;Digest of Internet Information, Groups and Other stuff “
    • Similar to Delicious with several extra features:
      • Allows users to highlight sections, attach sticky notes & share these annotations
        • private, public, or viewable only by members of a certain group
      • Group tag dictionary to enforce tagging consistency
      • A group administrator can define a set of recommended tags to help make tagging consistent
    • Smallest amount of users
  • Recommendation
    • Digg is best for public use because it has the largest amount of users
    • Delicious is the best combination of both public and private use, though it doesn ’t fully meet the needs of either
    • Diigo is best for private use and collaborative efforts within OCGR
  • Questions? Thank You.
