    • Agenda
      • Introduction
      • Taxonomy
      • Folksonomy
      • Tagging in Folksonomy
      • Visualizing Folksonomy
      • Folksonomy and Semantic Web
      • Metadata and Semantic Web
      • Folksonomy Advantages
      • Folksonomy Disadvantages
      • Conclusion
    • 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.
    • 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
    • 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
    • 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.
    • 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;>
    • 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
    • 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.
    • 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)
    • 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
    • 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.
    • Thank you
