  • 1. Collaborative Tagging
  • 2. Agenda
    • Introduction
    • Taxonomy
    • Folksonomy
    • Tagging in Folksonomy
    • Visualizing Folksonomy
    • Folksonomy and Semantic Web
    • Metadata and Semantic Web
    • Folksonomy Advantages
    • Folksonomy Disadvantages
    • Conclusion
  • 3. Taxonomy
    • One of the most common strategies for organizing content
    • Only admin / authorized person can add / edit categorize the content
    • Use of taxonomy is not possible in websites with user generated content
    • Content is constantly changing and its not possible to have a standalone taxonomy
    • No single party can enforce taxonomy in whole user community
      • Example, Wordpress blog categories.
      • To overcome the disadvantages in Taxonomy, Folksonomy introduced.
  • 4. Folksonomy
    • Folksonomy became popular in 2004
    • Folksonomy is a characteristic of web 2.0
    • Folksonomy = Collective Tagging = Tagging = Social Tagging = Social Indexing = Collaborative Tagging
    • Folksonomy
    • Online => Delicious Offline => Library Records
    • Folksonomy => Folk + Taxonomy
      • Folks => Done by people
      • Taxonomy => Classification of item into groups
  • 5. Tagging in Folksonomy
    • TAG
    • Tag is simply a freely chosen set of textual keywords.
    • Tags not created but specialists and created by users
    • Tag can be categorized with any word that defines a relationship between the online resource and a concept in the user's mind
    • Any number of words might be chosen, some of which are obvious representations, others making less sense outside the tag author's context.
    Resources Users Tags
  • 6. Visualizing Folksonomy
    • Tag cloud – Way to visualize tag in a Folksonomy.
    • Tag clouds represents by size, number of times the tag applied to single item and quality of content.
    • Tag clouds are interactive
    • Tags are hyperlinks thus allows users to drill down on the data.
    • Delicious is the first bookmarking site to introduce tagging concept.
  • 7. Folksonomy and Semantic Web
    • Folksonomy intended to make a body of information increasingly easy to search, discover, and navigate over time
    • Folksonomy hold a key in developing semantic web and information retrieval system.
    • Web content searchable through machine readable meta datas. Not sure every web authors have added metadata in their pages.
    • Time consuming to learn and use
    • How SE Categorize content in WEB
    • <meta name=&quot;keywords&quot; content=&quot;computing, computer software, computer&quot;>
    • <meta name=&quot;description&quot; content=&quot;Cheap widgets for sale&quot;>
    • <meta name=&quot;author&quot; content=“Mercy Livingstone&quot;>
  • 8. Metadata and Semantic Web
    • Examples of Metadata for Book
      • Title
      • Author
      • Date of Publication
      • Subject
      • Unique Indentifier (International Standard Book Number)
      • Number of pages
      • Language of text
  • 9. Metadata and Semantic Web
    • Example of Metadata for Audio
      • Album Name
      • Song title
      • Year
      • Composer
      • Contributing Author
      • Track Number
      • Album Artist
    • People also use “Dublin Core” metadata which consists of standard 15 metadata.
  • 10. Folksonomy Advantages
    • To provide additional keywords to help search engines and tag services add up your keyword counts and classify your post content.
    • To provide additional navigation on your site, like an index reference, helping the user find related post content.
    • Cheap, easy way to classify web content
    • Capable to adapt to user style
    • Scalability – easy for everyone use
    • Reflects user's vocabulary
    • Help machine to retrieve best information in the web.(If done with accuracy)
  • 11. Folksonomy Disadvantages
    • Polisemy - Same tag with different meaning
        • Ex, Chicken, Windows
    • Synonyms – Different tags with same meaning
        • Ex, Mate,Friend; Ocean, Sea
    • Plural Vs Singular
    • Acronym and Abbreviations
    • No spaces allowed (only single word)
    • Language Barrier
    • Organized by amateur
    • Anti-spam measure is tough
  • 12. Conclusion
    • Web is infinite, can’t rely on experts to classify things
    • Its upto end users to contribute
    • Single tag is not going to speak the language. The number of increase in tag that matters. Ex. Flickr
    • Some extend taxonomy also can’t be ruled out. Ex. Library Catalogue.
    • We have to capitalize on the benefits of both the systems.
    • University of Pennsylvania adopted Penn Tagg
    • Beyond the partnership with Taxonomy, Folksonomy moves forward in future classifying web towards creating semantic web.
